【摘要】合理使用节点的有限能量是无线传感器网络的关键技术之一,在LEACH 协议及其一般改进协议基础上,提出了一种新的改进算法.该算法通过等间隔分层和层中分簇方式来平衡节点间的能量消耗,选择簇首时综合考虑了节点的能量及到基站的距离,给出了具体的簇首选举算法,并在簇首的数据发送中引进了单跳和多跳相结合的路由协议.仿真结果表明,新的改进算法相对原有算法有明显改进,极大地延长了网络寿命.%The energy efficiency is key question which should be solved in the wireless sensor network. A new methods is introduced based on LEACH. The methods generate clusters by static hierarchical and dynamic parti tion. The residual energy and the position of the sensor node are considered as the parameter to optimize the process of cluster-head selection, and a modified multi-hop approaches is also introduced to the communication between clusterhead and BS. The simulation results show that the new strategy of cluster-head selection can improve the life time of sensors and networks.
