The research of WSN routing algorithm based on cluster head reappointment and multiple sink nodes

为延缓传感器网络寿命,减少网络能量消耗,通过分析LEACH路由算法的不足,提出一种基于簇首连任机制和多汇聚(sink)节点的无线传感器路由算法.即在成簇阶段采用一个簇首在多轮中连续担任簇首的机制,以减少每轮因选簇首而耗费的能量;在数据传输阶段使用多个sink节点接收簇首发来的信息,以降低通信中的能量消耗.仿真实验结果表明,该算法能有效延长网络生命周期且减少网络能量消耗.

According to the analysis of the disadvantages of LEACH algorithm,the wireless sensor network clustering algorithm based on cluster head reappointment and multiple sink nodes was presented to prolong the network lifetime and reduce energy consumption.This paper uses cluster head reappointment technology in the network clustering stage can avoid to select cluster head nodes frequently that consumes energy.The proposed algorithm uses multiple sink nodes in wireless sensor network to receive the messages from the cluster heads and then reduce the energy consumption in communication.The simulation result indicates that the proposed algorithm is very energy-efficient,and it can prolong the lifetime of the sensor network and reduce the energy consumption of the network.
