摘要
针对无线传感器网络中的能耗不均衡问题,提出一种基于天牛须搜索算法的负载均衡分簇路由协议算法(LEACH-BAS)。该算法引入候选簇首选举机制,使用天牛须搜索算法对簇首分布进行搜索优化,形成合理分簇。此外,在簇间路由通信时,考虑剩余能量因子和传输能耗因子来选择中继节点。仿真结果表明,LEACH-BAS算法的网络生命周期相比LEACH、EAMMH、LEACH-GA和LEACH-PSO算法分别延长了39%、22%、15%和8%。LEACH-BAS算法应用在WSN监测场景,能有效解决WSN中能量不足的问题,优化簇首节点分布,降低节点能耗,有效地延长网络生命周期。
In order to address the issue of the energy consumption unbalance in wireless sensor networks,an energy-efficient clustering routing algorithm based on beetle antennae search(BAS)for loading balance(LEACH-BAS)is proposed.The candidate cluster head election mechanism is optimized by the beetle antennae search algorithm to form a reasonable cluster.In addition,When routing data packet between cluster heads and the sink,the algorithm comprehensively considers the residual energy factor and the transmission energy factor to select the relay node.Simulation results show that LEACH-BAS exceeds the network lifetime of LEACH,EAMMH,LEACH-GA and LEACH- PSO by nearly 39%,22%,15% and 8% respectively.The LEACH-BAS algorithm is applied to the WSN monitoring scenario,which can efficiently solve the insufficient energy in WSN ,optimize cluster head distribution,reduce node energy consumption and significantly prolong the network life.
