摘要
无线传感器网络的路由协议是无线传感器网络研究的关键技术,在延长网络寿命,减少节点能耗方面有着重要的作用。提出一种基于LAC的改进分簇路由协议。该协议中,对LAC的簇头选择机制进行了改进,考虑了节点的能量和连通性。同时,对于LAC中的处于同一区域的节点,根据节点的分布形成不同大小的簇,使得簇头的负载更均匀,从而延长网络的生存时间。仿真结果显示:本协议能更好地延长网络的寿命。
In wireless sensor networks, routing protocol is the key technique, and plays an important role in prolonging network lifetime and reducing energy consumption. The improved clustered routing protocol based on LAC is proposed. In this protocol, the cluster head selection algorithm in LAC is improved for wireless sensor networks in terms of energy and connectedness. Meanwhile, the different clusters are generated in the same area by the node distribution. It may make the cluster heads load balancing to improve the network lifetime. Simulation results show that the protocol can improve the network lifetime.
