【摘要】为了均衡无线传感器网络的节点能耗,增强网络稳定性,设计并实现了一种基于分区的能耗均衡路由协议.该协议设计了一种优化的分区算法,将节点基于分区划分而形成簇,解决了先前协议中簇的个数和分布的随机性问题;在选举簇首时,综合考虑了节点剩余能量、簇内节点能耗均衡、簇内部总能耗三个方面,采用三级簇首选择机制,选择的簇首既能均衡节点能耗,又可以降低簇群总能量消耗;在数据转发时,普通节点选择距离最近的簇首,在不超过通信距离阀值时,簇首可以隔层选择下一跳簇首,有利于缓解无线传感器网络的"热区效应".仿真结果表明:相比MEET和DREEM-ME路由协议,该协议能更好地均衡节点能耗、增强网络稳定性、改善网络服务质量.%An energy-consumption balancing routing protocol based on regions is proposed to balance the energy consumption of wireless sensor network and enhance the network stability. The protocol designs an optimized region-divided algorithm which divides sensor nodes into clusters based on the regions to solve the random problem of clus-
ters'number and distribution in previous protocols. In selecting clusters,a three-level selectional mechanism of clus-ter heads is adopted after taking consideration the factors of the residual energy of sensor nodes,the cluster topology and the internal total energy consumption of cluster. In forwarding the data,general nodes can choose the nearest cluster head
which can select the next hop one in a two-upper level within the threshold of communication distance. Simulation results
suggest,compared with DREEM-ME and MEET protocols,the proposed protocol can better bal-ance the nodes'energy consumption,enhance the network stability and improve the quality of network service.
