| 摘 要： | LEACH协议是无线传感器网络中经典的分簇算法,但LEACH协议中簇首是随机产生的,存在簇首分布不均、网络拓扑和能量消耗不均衡的问题.基于此提出的LEACH-ER算法采用动态的簇首选举机制,将代表簇首间地理位置的RSSI信息和节点剩余能量引入选举权值,以均衡能量消耗和优化簇首分布.仿真结果表明,与LEACH算法相比,LEACH-ER算法有效地均衡了节点能耗,提高了能量利用率,从而大大地延长了网络寿命.

| Abstract: | LEACH Protocol is a classic clustering algorithm for Wireless Sensor Networks.In this protocol,cluster heads was randomly generated,which bring about several problems such as cluster heads uneven distribution and Energy consumption imbalance.This article proposes an improved algorithm named LEACH-ER,which aims at improving the existence problems mentioned above and makes out a prioritization scheme.Dynamic and multiple Electoral mechanism are adopted,LEACH-ER combines the RSSI information between cluster he... |
