| 摘 要： | 针对无线传感器网络LEACH协议在簇头选择、簇头与Sink通信方面存在的不足,以均衡能耗和节省能量为出发点,提出对LEACH协议的改进方案.假设协议中的簇头只能在路由节点中产生,感知节点只能就近成为簇成员,选举出的簇头之间需要再进行分簇,远离Sink的簇头作为靠近Sink的簇头的簇成员.仿真实验结果证明,改进后的协议有效地延长了网络的生命周期.

| Abstract: | For the weakness of LEACH in selecting cluster head and communicating between cluster heads and Sink,improved LEACH is put forward,in order to balance energy consumption and save energy.It is assumed that cluster heads only can be generated among routing nodes,and sensing nodes become cluster members of the nearest cluster head.Meanwhile,routings among cluster heads should be formed in a way,that the cluster head far away from Sink need to be a cluster member of the one close to Sink.The simulation results show that the improved LEACH prolongs the lifetime of network. |
