Meru Wireless LAN解决方案快速部署指南说明书
DEPLOYMENT BRIEFWi-Fi Solution for Small K-12 School (< 25 AP)OVERVIEWFor more information, visit .technology in our Channel Layering design, we are able to add capacity to the wireless network in such areas. Each deployed channel is a contiguous layer throughout the area, allowing the ability to create multiple virtual cells to handle the high density.Based on internal testing and the assumption that K-12 schools will have a mix of single-, dual-, and three-stream clients, along with a wide variety of application use including streaming music, high-definition video, and other web traffic, we have designed the following chart to assist in choosing how manychannels to deploy in a high-density area.• When configuring channel layers, co-locate APs in a “pod” approximately 7–10 feet apart.• Turn on load balancing to evenly distribute usage across all access points.OUTSIDE AREASWith mobility being a key functionality in K-12 environments, many schools require coverage outside the classroom in hallways, quad areas, and outdoor sports areas.• If the outside requirement is for coverage only, a site survey is recommended to determine the placement of APs and the antenna types.• If the outside requirement will include high density, determine how many APs are needed based on the estimated device count for the specified area.• Determine which external antenna best fits the environment. Many schools install the APs inside a building, but mount external antennas on the outside of the building.THE WIRELESS NETWORK INFRASTRUCTUREThe following equipment is recommended for a K-12 school with fewer than 25 APs• MC1550 controller• AP832 802.11ac access point• Identity ManagerCONFIGURE YOUR WIRELESS NETWORKSK-12 schools require a minimum of three wireless networks: for students, staff, and guests. The authentication for these three networkswill vary based on the school’s security policy. It is recommended that staff and student networks utilize 802.1X authentication with Active Directory integration. Guest authentication can be given through a sponsor or a self-register captive portal process.To access the controller, open up a web browser and enter the IP address or DNS name in the URL box. For the quickest configuration, navigate to the Wizards tab on the left menu bar.• Validate the initial controller setup configuration, including IP address, subnet, gateway, country code, time zone, and system date/ time• Upload the license file to activate access points• View and validate current APs connected to the controller• Start scanning the environment to allow the controller to determine the best channel to use• To create the three recommended wireless networks (Guest, Student, Staff), click the Add button and enter the SSID name, security mode, and VLAN IP information• Review the controller configuration, then save it• Be sure to install an SSL certificate on the controller• Once the APs are connected to the controller, devices will be able to connect to Wi-FiINTEGRATE IDM WITH THE CONTROLLERMeru Identity Manager (IDM) gives you the ability to easily manage guest users and allow quick BYOD onboarding. The Smart Connect feature dramatically reduces IT workload by enabling students and teachers to access the secure wireless network with just a few quick steps.IDM also offers a RADIUS feature that allows 802.1x authentication for schools that may not have an external RADIUS server. The tracking and reporting capabilities in IDM are also extremely beneficial in ensuring appropriate use of your school’s wireless network.Once the initial setup of IDM is complete:• Add the controller as a RADIUS client. Meru IDM automatically configures the controller to begin communicating with IDM. (On the controller, be sure to add the firewall filter ID created during the automated configuration process for the “Guest” security profile.) • Configure Guest Connect by customizing the sponsor portal settings for guest management access.• Configure Smart Connect profiles and policies to allow automatic BYOD onboarding for students and staff.Meru Networks 894 Ross Drive, Sunnyvale, CA 94089T +1.408.215.5300F +1.408.215.5301E *************************For more information about Meru Networks, visit or email your questions to:*************************Meru Networks | Copyright © 2013 Meru Networks, Inc.

Bonjour is the protocol used by these Apple products to communicate with other devices limited to the same Layer 2 network. This can pose a problem because most schools have multiple VLANs distributed throughout their campus. Bonjour Service Control allows the communication of Bonjour services across multiple VLANs by controlling service discovery and advertisement and by using flexible policy management based on service type, location, and user groups.For example, with Service Control enabled, a teacher’s wireless IPad on VLAN 10 can communicate with a wired Apple TV connected to a projector on VLAN 50. At the same time, you can prohibit student iPads on VLAN 20 from connecting to the projector with Service Control policy management.To configure this feature, enable Service Control in the Meru controller’s global settings:•Define how the services will be discovered using a wired gateway list •Specify the types of services that may be discovered •Define the locations based on APs • Create Service Control policies based on user groups, services, and locationSUMMARYWith Meru, you have the tools you need to provide an uninterrupted learning experience with anywhere, anytime Wi-Fi access for students, teachers, and guests. A Meru network:•Is simple to deploy and expand •Speeds onboarding with automated provisioning and guest management •Is easy to manage centrally, requiring a minimum of support •Gives you visibility into what your students are doing on the network • Provides smooth roaming, reliable connectivity, and predictable performance, even in high-density environments。
谈谈对广告的看法英语作文
My Perspective on AdvertisingAdvertising, a ubiquitous aspect of modern society, plays a pivotal role in shaping our consumer behaviors and cultural landscape. It is a powerful tool that has the ability to persuade, entertain, and inform. However, my view on advertising is complex, encompassing both its positive and negative impacts.On the positive side, advertising serves as a medium of communication, connecting businesses with potential customers. It introduces new products and services, educating the public about their existence, features, and benefits. This, in turn, encourages competition among businesses, leading to innovation and better quality products. Additionally, advertising can be a source of creativity and art, with its visuals and messaging often pushing the boundaries of traditional advertising techniques.However, the negative aspects of advertising cannot be ignored. Its persuasive nature can sometimes lead to unethical practices, such as exaggeration or misrepresentation of products. This can mislead consumers, leading to dissatisfaction and disappointment. Moreover, advertising often promotes a consumerist culture, encouraging individuals to constantly purchase new items, which can be environmentally unsustainable and psychologically unhealthy.Furthermore, the excessive presence of advertising in our daily lives can be intrusive and annoying. From TV screens to online platforms, it is hard to escape the constant bombardment of ads. This can lead to a feeling of being overwhelmed and disconnected from the real world.In conclusion, my view on advertising is that it is a double-edged sword. While it serves as avaluable tool for businesses and can be a source of creativity, it also has the potential to mislead, encourage consumerism, and invade our personal spaces. Therefore, it is crucial for both advertisers and consumers to be mindful of its impacts and use it responsibly.。
《世纪商务英语》翻译讲义Advertisements
《世纪商务英语》翻译讲义AdvertisementsUnit 7 Advertisements1.Adverting is a way of bringing information to the public for the purpose of selling a product, a service, an idea, or an event. The information is transmitted by means of the printed word or even the air. It may be presented as a simple statement of fact, or, as is more frequently the case, it may be offered in colorful or even emotional language. All advertising is intended to stimulate people to do some specific thing, such as buying a product, ordering a service, joining an organization, attending a meeting, or thinking sympathetically about a situation. Each advertising is paid for by a person, a group, an organization, or a business enterprise seeking to advance his or its goals.Consumer advertising can be directed to different parts of a market. For example, producers advertise through magazines and radio and television programs that appeal to the portion of the market they wish to reach. A cereal manufacturer would schedule commercials for television cartoon shows in order to make children aware of a product. A tire maker would use air ads during sporting events to appeal to the adult male audience.Trade advertising is aimed at middlemen of all kinds. Trade ads try to persuade wholesalers and retailers to stock specific goods. Industrial advertising is directed to producers of manufactured goods. Agricultural advertising goes to the agricultural producers. Professional advertising is aimed at people such as doctors, teachers and architects, who recommend products but do not purchase them directly./doc/a6dbcee8dd3383c4bb4cd2fa.html nguage features(1)Verbs, adjs, pronouns, coinageNestle Ice Cream: Take time to indulge!

广告英语四级作文The Power of Advertising。
Advertising is a powerful tool that can influence and persuade people to buy certain products or services. It is a form of communication that aims to inform and persuade potential customers about a particular product or service. Advertising is everywhere in our daily lives, from billboards on the streets to commercials on television and social media. It plays a significant role in shaping consumer behavior and influencing their purchasing decisions.One of the main purposes of advertising is to create brand awareness and build a positive image for a product or service. Through creative and persuasive messaging, advertisers can capture the attention of their target audience and convey the benefits and features of their products. This can help to differentiate a brand from its competitors and create a strong brand identity in the mindsof consumers. For example, a well-crafted advertising campaign can make a product seem more desirable and attractive, leading consumers to choose it over other similar products.In addition to creating brand awareness, advertising also serves as a means of providing information to consumers. Advertisements often highlight the key features and benefits of a product, as well as any promotions or special offers that may be available. This can help consumers make informed decisions about their purchases and choose products that best meet their needs and preferences. For example, a car advertisement may highlight the fuel efficiency, safety features, and advanced technology of a particular model, helping consumers understand the value of the product and why they should consider purchasing it.Furthermore, advertising has the power to shape consumer behavior and influence their purchasing decisions. Through strategic messaging and emotional appeals, advertisers can create a sense of urgency and desire for their products. For example, a limited-time offer or acompelling narrative in an advertisement can motivate consumers to take action and make a purchase. This can lead to increased sales and revenue for businesses, as well as a loyal customer base that trusts and values the products being advertised.However, it is important to note that advertising can also have negative effects on consumers. For example, misleading or deceptive advertising can lead to false expectations and dissatisfaction among consumers. Additionally, excessive advertising can be intrusive and annoying, leading to a negative perception of the brand and its products. It is essential for advertisers to be ethical and responsible in their messaging and ensure that they are providing accurate and truthful information to consumers.In conclusion, advertising is a powerful tool that can influence and persuade consumers to buy certain products or services. It plays a significant role in creating brand awareness, providing information to consumers, and shaping consumer behavior. However, it is important for advertisers to use their power responsibly and ethically to ensure thatthey are providing value to consumers and building trust in their brands. By doing so, advertising can be a positive force that benefits both businesses and consumers.。

如何改善服务态度英语作文
As a high school student who has had the pleasure of interacting with various service providers, Ive observed a wide range of attitudes that can significantly impact the customer experience. In this essay, I will share my insights on how to improve service attitudes and create a positive environment for both customers and service providers.First and foremost, empathy is the cornerstone of excellent service. Its essential for service providers to put themselves in the customers shoes and understand their needs and expectations. When I visited a local bookstore, the staff member who greeted me was genuinely interested in helping me find the book I was looking for. She asked about my preferences and even recommended a few titles that I hadnt considered. This personal touch made me feel valued and appreciated.Secondly, active listening is a crucial skill for service providers. Customers appreciate when their concerns are heard and addressed. For instance, during a recent visit to a restaurant, I noticed that the waiter listened attentively to our order and made sure to clarify any special requests. This attention to detail ensured that our dining experience was enjoyable and met our expectations.Moreover, maintaining a positive and friendly demeanor can go a long way in enhancing the service experience. A smile, a warm greeting, or a simple conversation can create a welcoming atmosphere. I recall visiting a coffee shop where the barista greeted me with a smile and engaged in a friendly chat while preparing my drink. This interaction brightened my day and made me feel more than just another customer.In addition to these interpersonal skills, service providers should also strive for continuous improvement in their knowledge and expertise. Being wellinformed about the products or services they offer can help build trust and credibility with customers. For example, when I needed assistance with a technical issue at a computer store, the salespersons indepth knowledge of the products and their features helped me make an informed decision.Another aspect to consider is the importance of flexibility and adaptability in service delivery. Customers appreciate when service providers are willing to go the extra mile to accommodate their needs. I once had a memorable experience at a hotel where the staff arranged a special birthday surprise for my friend, even though it was not part of their standard offerings. This gesture demonstrated their commitment to customer satisfaction.Furthermore, timely and effective communication is vital in managing customer expectations and addressing any issues that may arise. For instance, when I ordered a product online, the seller kept me updated on the delivery status and promptly responded to my inquiries. This transparency helped alleviate any concerns and built trust between the seller and me.Lastly, feedback is an invaluable tool for service providers to identify areas of improvement and enhance their service quality. Encouraging customers to share their experiences and suggestions can lead to meaningful changes that benefit both the service providers and their customers. I have noticed that businesses that actively seek and implement customerfeedback tend to have a more satisfied and loyal customer base.In conclusion, improving service attitudes involves a combination of empathy, active listening, a positive demeanor, continuous learning, flexibility, effective communication, and valuing customer feedback. By incorporating these elements, service providers can create a memorable and satisfying experience for their customers, fostering longterm relationships and a positive reputation in the marketplace. As a high school student, Ive seen the difference that a positive service attitude can make, and I believe that these principles can be applied across various industries to enhance the overall customer experience.。

advertisements AdvertisementsIntroductionAdvertisements play a crucial role in our daily lives, constantly bombarding us with messages aimed at persuading us to buy products, support causes, or adopt a certain lifestyle. They are ubiquitous, appearing on television, radio, billboards, and even our smartphones. This document takes a closer look at advertisements, exploring their purpose, techniques used, and the impact they have on consumers.Purpose of AdvertisementsAdvertisements are primarily created to influence consumer behavior. The ultimate goal is to persuade people to purchase products or services and build brand loyalty. Advertisements aim to communicate the benefits and features of a specific product or service to potential buyers. They also serve as a way for companies to differentiate themselves from their competitors and create a unique brand identity.Advertising TechniquesTo captivate consumers' attention and persuade them to take action, advertisers employ a variety of techniques. These techniques are designed to trigger emotional responses, create a desire for the product or service, and ultimately drive sales. Some common advertising techniques include:1. Emotional appeal: Advertisements often tap into consumers' emotions, using storytelling, relatable characters, or sentimental music to create a connection with the audience. By evoking emotions such as joy, nostalgia, or even fear, marketers can make a lasting impression.2. Celebrity endorsement: Many advertisements feature celebrities who lend their credibility and popularity to a product or brand. By associating with a well-known figure, companies hope to leverage the celebrity's influence to boost sales and enhance the brand's image.3. Humor: Advertisements that make people laugh are more likely to be remembered. Humor can be an effectivetechnique for creating a positive association with a product or service, making it more relatable and engaging.4. Fear appeal: Some advertisements tap into consumers' fears or insecurities to drive action. By highlighting potential negative consequences or problems, marketers aim to create a sense of urgency and convince consumers that their product or service can provide a solution.Impact on ConsumersAdvertisements have a significant impact on consumers' attitudes, behaviors, and purchasing decisions. While some advertisements can inform and educate, others can manipulate and deceive. The persuasive power of advertisements can create both positive and negative outcomes for consumers.Positive impacts include:1. Awareness and information: Advertisements inform consumers about new products, services, and innovations in the market. They provide necessary information that allows potential buyers to make informed decisions.2. Entertainment value: Well-crafted advertisements can be entertaining and enjoyable to watch or listen to. They enhance the overall media experience and create a positive association with the brand.3. Social influence: Advertisements often reflect societal trends and values. They can shape consumer beliefs, attitudes, and behaviors by promoting social issues, diversity, and inclusivity.Negative impacts include:1. Manipulation and deception: Some advertisements use misleading tactics to manipulate consumers into making unnecessary purchases or believing false claims. This can lead to buyer's remorse and dissatisfaction.2. Unrealistic expectations: Advertisements often feature models and celebrities who represent an idealized image of beauty or success. This can create unrealistic expectations and contribute to low self-esteem and body image issues.3. Consumerism and materialism: Advertisements often encourage constant consumption and the pursuit of material possessions. This can contribute to a culture of materialism, where individuals prioritize the accumulation of goods over personal well-being and relationships.ConclusionAdvertisements have become an integral part of modern society, shaping our attitudes, behaviors, and purchasing decisions. While they serve the purpose of informing and persuading, it is important for consumers to approach advertisements critically and discerningly. By understanding the techniques used and the potential impact on our lives, we can make more informed choices and develop a healthier relationship with advertising.。

对广告的看法英语作文
对广告的看法英语作文In today's world, advertising is ubiquitous, infiltrating every aspect of our lives. It is a powerful tool that businesses use to promote their products and services, and it has become an integral part of our consumer culture. Here are my thoughts on the subject.Firstly, advertising plays a crucial role in informing consumers about new products and services. It helps to create awareness and educate the public about the benefits and features of various offerings. Without advertisements, it would be challenging for consumers to stay updated with the latest innovations and market trends.Secondly, advertising can be a source of inspiration and creativity. Many advertisements are designed with artistic flair and innovative storytelling that can captivate and entertain the audience. They often use humor, emotion, and visual appeal to make a lasting impression, which can be appreciated as a form of art.However, there are also downsides to advertising. One of the most significant concerns is the promotion of materialism and consumerism. Advertisements can sometimes encourage people to buy things they do not need, leading to overconsumption and a focus on material possessions rather than personal growth and well-being.Moreover, the ethics of advertising can be questionable. Some ads may use manipulative tactics to persuade consumers, such as creating a sense of urgency or fear. There are also instances where advertisements can be misleading or contain false claims, which can misinform and deceive the public.Another issue is the invasion of privacy that comes with targeted advertising. With the rise of digital marketing, companies collect data on consumer behavior to deliver personalized ads. While this can be seen as a way to provide relevant content, it also raises concerns about how personal information is used and protected.In conclusion, advertising is a double-edged sword. It serves as an essential medium for businesses to reach potential customers and can be a source of creativity and inspiration. However, it also has the potential to promote negative values and raise ethical and privacy concerns. As consumers, it is crucial to be aware of these aspects and make informed decisions about the products and services we choose to support.。

Service Advertisement and Discovery in Mobile Ad hocNetworksLiang ChengLaboratory Of Networking Group (LONGLAB, )Department of Computer Science and Engineering, Lehigh University19 Memorial Drive West, Bethlehem, PA 18015+1 610 758 5941cheng@ABSTRACTService advertisement and discovery is an important component for ad hoc communications and collaboration in ubiquitous computing environments. In this paper, a lightweight service advertisement and discovery protocol for MANET (Mobile Ad hoc NETworks) based on ODMRP (On-Demand Multicast Routing Protocol) is presented. Its service advertisement and discovery information is piggybacked in ODMRP routing control packets. Thus the implementation workload and resource consumption are lightweight as long as mobile devices in MANET support multicast routing functionality. The protocol avoids excessive traffic overhead of periodic advertisements since only updated service advertisements are distributed and the service query/reply mechanism in the pull model is used. Moreover, the pull model deals with mobility in MANET because the advertised and registered service can be obsolete after a certain period of time due to the mobility of either the server or client devices.KeywordsService advertisement and discovery, mobile ad hoc networksINTRODUCTIONA service is an entity that can be used by a person, a software program, or another service. It may be a computation, storage, a communication channel to another user, a software filter, a hardware device, or another user. Service advertisement and discovery is an important component for ad hoc communications and collaboration in ubiquitous computing environments since it enables communication and collaboration entities to provide services to peers and to be aware of and use the available services from peers. In this paper, service discovery is an interchangeable terminology to the service advertisement and discovery.Related WorkThe topic of service advertisement and discovery has been extensively researched in technologies such as Jini [1] and the service location protocol [2].JiniThe Jini technology infrastructure and programming model are built to enable services to be offered and found in networking environment. These services take advantage of Jini technology to announce their presence to other services and users, to discover each other, and to make calls to each other. In this paper, the focus is the service advertisement and discovery in Jini technology, which includes a trio of protocols called discovery, join, and lookup.A pair of these protocols, discovery/join, fulfills the service advertisement functionality. It occurs when a device is plugged in. The discovery protocol is used when a service looks for a lookup server with which to register. The join protocol is used when a service has located a lookup server and wishes to join it. The lookup protocol is used when a client or user needs to locate and invoke a service described by its interface type (written in the Java programming language) and possibly, other attributes.Figure 1. Jini processes of discovery/join/lookup. Figure 1 outlines the discovery/join/lookup processes in Jini. The discovery/join is the process of adding a service to a Jini system. A service provider, e.g., a device or software, is the originator of a service. First, the service provider locates a lookup server by multicasting a requeston the local network for any lookup server to identify itself (discovery in Figure 1). Then, a service object for the service is loaded into the lookup server (join in Figure 1), which contains a Java programming language interface for the service including the methods that users and applications will invoke to execute the service, along with any other descriptive attributes. The service is now ready to be looked up and used.A client locates an appropriate service by its type, i.e., by its interface written in the Java programming language, along with descriptive attributes that are used in a user interface for the lookup server. Then the service object is loaded into the client to be invoked.Service Location ProtocolService Location Protocol (SLP) establishes a framework for service discovery using three types of agents that operate on behalf of network-based software: (i ) Service Agents (SA) advertise the location and attributes on behalf of services, (ii ) Directory Agents (DA) aggregate service information, and (iii ) User Agents (UA) perform service discovery on behalf of client software.Figure 2. Methods of service discovery in SLP.Figure 2 illustrates active and passive methods for service discovery in SLP. In active discovery, UAs and SAs multicast SLP requests to the network. In passive discovery, DAs multicast advertisements for their services and continue to do this periodically in case any UAs or SAs have failed to receive the initial advertisement. SLP has two modes of operation: (i ) when a DA is present, it collects all service information advertised by SAs, and UAs unicast their requests to the DA, and (ii ) in the absence of a DA, UAs repeatedly multicast the same requests they would have unicast to a DA. SAs listen for these multicast requests and unicast responses to the UAs if it has advertised the requested service.DiscussionThe Jini discovery architecture is similar to that of SLP. Jini agents discover the existence of a Jini Lookup Server, which collects service advertisements in a manneranalogous to DAs in SLP. Jini agents then request services on behalf of client software by communicating with the Lookup Server. Unlike SLP, however, where DAs are optional, Jini requires the presence of one or more Lookup Servers.The above service discovery approaches encounter overhead problem when they are applied to mobile ad hoc networks (MANET) because they were not designed for mobile ad hoc networks by considering that MANET has dynamic network topology. They have to send explicit multicast packets for service discovery frequently in addition to the multicast control packets. This wastes precious bandwidth and battery resources, and causes extra traffic in MANET. In this paper, a lightweight protocol for service discovery in MANET is presented, which is based on On-Demand Multicast Routing Protocol (ODMRP). Section 2 presents the new service advertisement and discovery protocol in terms of bootstrapping mechanism in the push model and the query/reply mechanism in the pull model, based on the ODMRP, to achieve lightweight service discovery and deal with device mobility. Section 3 discusses the protocol performance and concludes this paper with future work.SERVICE DISCOVERY IN MANETIn this research, service advertisement and discovery addresses how network devices discover what types of services exist in the network. Multicast is used for service discovery in MANET because of (i ) the broadcast nature of wireless communication environment, (ii ) the infrastructureless feature of MANET, and (iii ) the one-to-many character of service advertisement and discovery. Since multicast protocols are not as well established and supported in infrastructure-less networking environment as in infrastructured networks, multicast protocols for MANET are studied first.Multicast Protocol for MANETSeveral multicast protocols have been proposed to support multicast in mobile ad hoc networks. A performance-comparison study of multicast protocols for MANET in a common realistic simulation environment is reported in [3]. It provides quantitative performance analysis of five protocols with different characteristics: adhoc multicast routing (AMRoute) [4], on-demand multicast routing protocol (ODMRP) [5], ad hoc multicast routing protocol utilizing increasing id-numbers (AMRIS) [6], core-assisted mesh protocol (CAMP) [7], and flooding.According to the research results, ODMRP is very effective and efficient in most simulation scenarios comparing to other multicasting routing protocols in MANET. Thus, in this research, ODMRP is chosen to support service discovery in MANET. Based on the ODMRP, both push and pull models are implemented for service discovery in MANET considering service mobility and network-resource saving. One approach is the bootstrapping mechanism in the push model. The other is the query/reply mechanism in the pull model. Assume that all protocols are IP based.Bootstrapping Mechanism in the Push ModelEvery mobile device that provides a service, which is called a server, multicasts an advertisement in MANET. Each server and its possible consumers make a multicast group. The advertisement includes the service name, the server's unicast address/port pair, and the protocol type that a client should use to request the service. Table 1 illustrates the advertisement format. Table 2 shows the combination of an ODMRP join query packet header with the service advertisement, where the “Reserved” field specifies whether a service advertisement is attached. The multicast group IP address for the service is the IP address of the multicast group that consists the server and its possible consumers.Table 1. Format of Service Advertisement1 byte 1 byte 1 byte 1byteType Option Field Time to Live Service PortServer Address (in unicast form)Service Name (ID)Protocol Type ReservedOptional FieldsType: 0x01 as service advertisement.Service Port: The port number of the service pointOption Field: 0, no optional information1, optional fields at the endServer Address: The unicast IP address of the serverService Name: The index or the name of the serviceTime to Live: Geographical scope the service covers interms of the number of hopsProtocol Type: Protocol type that the server and clients use Reserved: 0, ignored on receptionOptional Fields: Service description for multi-level servicesTable 2. Revised ODMRP Join Query Packet Header1 byte 1 byte 1 byte 1byteType Reserved Time to Live Hop Count Multicast Group IP Address for the Service Other Fields in ODMRP Join Query Packet HeaderService AdvertisementAny mobile device with applications interested in this service stores the advertisement in its local service registry, and sends a service awareness reply subject to resource limitations. A join reply packet is used without any attachment because it already provides sufficient information as a service awareness reply. Table 3 highlights the necessary fields in the join reply packet as a service awareness reply, where the “Reserved” field specifies whether a packet is a service awareness reply. The multicast group IP address for the service is the IP address of the multicast group, which consists the server and its possible consumers.Table 3. Format of ODMRP Join Reply Packet as a ServiceAwareness Reply1 byte 1 byte 1 byte 1byteType CountRF ReservedMulticast Group IP Address for the ServiceOther Fields in ODMRP Join Reply PacketSender IP Address (in unicast form)Other Fields in ODMRP Join Reply PacketOnce some clients send back service awareness replies, the server sends its updated service advertisements by piggyback in ODMRP join query packets. Otherwise it will wait for explicit queries from clients and reply back in the pull model, which is illustrated in the following section. Query/Reply Mechanism in the Pull ModelAssume that services have well-known service names, such as "printing" or "address book", and corresponding unique service IDs.Once a device or an application needs a service, it first gets the service ID and then sends a query to a well-known multicast address, which corresponds to the service query multicast group, asking about the existence of the service. The service query multicast group consists of servers and devices that support the service query/reply mechanism.The format of the service query message is the same as that of the service advertisement, which is illustrated in Table 1. However, the content is different: (i) the “Type” field is set to 0x02 as service query, (ii) the “Option” field is 0, and (iii) the “Service Name” is the service ID of the queried service. Since it is also piggybacked in an ODMRP join query packet, correspondingly, the “Reserved” field in Table 2 specifies whether a service query is attached. Moreover the Multicast Group IP Address field is set to the well-known multicast address for service queries.The format of the reply message for a service query is also the same as that of the service advertisement illustrated in Table 1. When a device receives a service query, if it supports the service query/reply mechanism, it waits for a random time to check whether there is already a reply message with latest information that has been issued by a device. If affirmative, it ignores the service query message.Otherwise, it fills in the blank fields such as Time to Live, Server Address, Service Port, Protocol Type, and/or the Option Field(s), if such information is available locally, and sends the reply message. The server always replies to the service query message with the updated service information. The random timer may suppress multiple reply copies being sent at the same time to save bandwidth. CONCLUSIONSBased on the ODMRP (On-Demand Multicast Routing Protocol), a lightweight service advertisement and discovery protocol is designed for ad hoc communications and collaboration in ubiquitous computing environments. Its service discovery information is piggybacked in the ODMRP routing control packets. Therefore the implementation workload and resource consumption are lightweight as long as the mobile devices support multicast routing functionality in mobile ad hoc networking environment.Moreover this implementation avoids excessive traffic overhead of periodic advertisements since only updated service advertisements are distributed and the service query/reply mechanism in the pull model is used. Furthermore the pull model deals with mobility in the network because the advertised and registered service can be obsolete after a certain period of time due to the mobility of either the server or client devices.Future WorkIt is observed that existing multicast protocols, either with tree configuration or mesh configuration such as ODMRP, has not considered the signal-to-noise ratio (SNR) of the wireless communication link. In fact, in MANET, minimum-hop design without considering SNR information is not always desirable. For example, if the minimum-hop path includes a “weak” link, illustrated in Figure 3, then data transmitted along this path may incur a significant amount of packet loss. Moreover, computing minimum-hop paths when a certain link is marginal (i.e., oscillating between the up and down states) will lead to route oscillation. The subsequent out-of-order arrival of packets of a particular session at the destination node results in inefficiencies in certain higher-layer protocols [8]. In the scenario of this research, the service discovery in MANET, especially when we consider service invocation using mobile objects, would suffer from the "weak link" and the route oscillation. Thus we will study an SNR-based ODMRP (SODMRP) in MANET for ad hoc communications and collaboration in ubiquitous computing environments.Figure 3. Min-hop path vs. quality-link path REFERENCES1.W. K.
