摘　　要：为解决网络能量瓶颈问题,将一对多无线可充电传感器网络(Wireless rechargeable sensor networks,WRSNs)划分成多个正六边形充电簇,分析基于Flooding(洪泛)路由协议和Gossiping路由协议下充电簇内的存活节点数和剩余能量的变化情况,以及2种协议对充电簇能耗均衡度的影响.仿真结果表明:与Flooding协议相比,Gossiping协议能够减少充电簇内的死亡节点数,减缓充电簇剩余能量的下降,延长网络寿命,但能耗均衡度低;适合传统WSNs的路由协议不一定适合WRSNs;针对基于分簇的一对多WRSNs,为改善充电簇的能耗均衡度,可以从设计新的路由协议或构建合适的充电簇两方面着手进行.In order to solve network energy bottlenecks problem,the one to multiple charging wireless rechargeable sensor networks(WRSNs)is divided into multiple regular hexagonal charging clusters.Based on Flooding routing protocol and Gossiping routing protocol,the changes of the number of surviving nodes and residual energy in the charging cluster are analyzed,and the effects of the two protocols on the energy consumption balance of the charging cluster are discussed.The simulation results show that compared with Flooding protocol,Gossiping protocol can reduce the number of dead nodes,slow down the decrease of residual energy in the charging cluster,and prolong the network life,but the energy consumption balance is low-the routing protocol suitable for traditional WSNs is not suitable for WRSNs.Therefore,for cluster-based one-to-many WRSNs.In order to improve the energy consumption balance of the charging cluster,designing a new routing protocol or constructing suitable charging clusters should be considered.
