摘要:

为了降低节点能量消耗,延长网络生存周期,提出一种基于混沌粒子群算法(Chaotic Particle Swarm Optimization, CPSO)的无线传感器网路由协议。该协议改进了LEACH(Low Energy
Adaptive Clustering Hierarchy)协议的簇头选择机制,考虑节点剩余能量、簇头到基站(Based Station)的距离等因素,通过混沌粒子群算法对簇头选举进行优化。簇头选举后,通过多跳算法对簇头到
基站的通信方式进行优化。仿真结果表明,与传统的LEACH协议比较,新协议能减少能量消耗,延长网络寿命。

Abstract:

In order to reduce the energy consumption of nodes and prolong the lifetime of wireless sensor networks (WSN), a routing protocol based on CPSO is proposed. The
protocol improves the cluster-head selection mechanism based on the Low Energy Adaptive Clustering Hierarchy (LEACH), it considers some factors like nodes’ residual energy,
distance to base station. It optimizes cluster-head selection by CPSO and then optimizes the communication between base station and cluster-head by multi-hop algorithm. The
simulation results show that the new protocol can save energy and prolong the lifetime of WSN compared with the LEACH.
