LEACH无线传感器网络中增加协作传输的能耗研究
摘要
针对LEACH分簇路由协议存在簇间能耗不均的不足
利用分集增益消除多径衰落的特点
将协同通信的思想应用于无线传感器网络
解决无线传感器网络中LEACH协议下的簇间能耗不均衡问题。仿真结果证明:当节点间距离大于阈值距离时
协作传输可以有效地降低节点的能耗
从而均衡了整个网络的能耗。
Abstract
Aiming at the shortcomings of unbalanced energy consumption among clusters in LEACH
cooperative transmission
whose advantage is that diversity gain can relieve the effect of the multipath fading
is adopted to solve the problem of unbalanced energy consumption among clusters in wireless sensor networks.Simulation results prove that when distance between nodes is larger than threshold
cooperative transmission can reduce energy consumption of the nodes effectively
which balances the energy consumption of the whole networks.
