| 摘 要： | LEACH是无线传感器网络(Wireless Sensor Network,WSN)中一种经典的分层式路由协议,在此基础上通过对LEACH成簇算法及簇间路由的改进,提出了一种新的均衡能量消耗分簇路由协议。该协议在无线传感器网络成簇过程中充分考虑了传感器节点的能量状态,同时簇首向基站的通信采用基于能量的簇间路由。理论分析及仿真结果表明,改进的协议能够均衡传感器节点的能量消耗,有效地延长网络寿命。

| Abstract: | LEACH(Low-Energy Adaptive Clustering Hierarchy) is a classic hierarchical routing protocol for wireless sensor networks.In this paper,we propose a new energy-balanced clustering protocol,which gives full consideration to sensor nodes' energy state in the clustering process and improves both the clustering scheme and inter-cluster routing of LEACH.Both theoretical analysis and simulation results show that our new protocol can balance the nodes' energy consumption and extend the network lifetime effectively. |
