WSN中一种基于LEACH的协同通信算法的研究

近年来,协同通信在无线传感器网络中取得了很大的应用,重点分析和研究了一种基于低功耗自适应集簇分层型协议（LEACH）的协同通信算法;在该算法中,通过选择合适的协同节点来发送数据可以有效的减少簇头节点的能量消耗,并且与多跳传输相比,又节省了路由更新耗费的能量,实验仿真证明基于LEACH的协同算法（LEACH-COOP）在能量消耗上与LEACH和基于LEACH的簇头多跳算法（LEACH-MH）相比表现出了更优的性能。

A Cooperative Communication Algorithm Bsaed on LEACH in WSN

Recently,Cooperative communicative achieves wide application in WSN（wireless sensor network）.This paper analyzes a cooperative communication algorithm based on LEACH（Low Energy Adaptive Clustering Hierarchy）.This algorithm,by selecting the proper cooperative nodes for data sending,could effectively reduce the energy consumption of cluster head nodes.As compared with the multi-hop transmission,it could also save the energy sonsumption of routing updates.Simulation experiments indicates that LEACH-COOP（cooperation algorithm based on LEACH） are better than LEACH and LEACH-MH（cluster head multi-hop algorithm based on LEACH） in energy consumption.
