【摘要】 无线传感器中路由协议的选择制约着网络寿命,选择一个好的路由协议可以有效地延长网络的生存时间。根据层次型拓扑控制的分簇机制所提出的LEACH协议有效地延长了网络的生存时间,但是它在能量均衡上还存在问题。目前学术界也提出了许多的改进方法,本文是基于LEACH协议所存在的不足,在选簇上做了改进,提出新的N-LEACH协议,优化传感器节点的能量均衡,并通过Matlab进行仿真。仿真结果表明,改进的选簇算法有效地延长了网络的生存时间。更多还原

【Abstract】 Select one routing protocol in the wireless sensor network can determine the lifetime of the network,choose a suitable routing protocol can prolong the lifetime of the network.As we know the Leach protocol which is based on the clustering algorithm is effectively prolong the lifetime of the network,but it still exist some problem on energy balance.Now many improvwd mathods has been proposed.This paper is based on Leach algorithm’s defects,change the algorithm on the selecting clusters,and propose a new LEACH protocol-N-LEACH,then use the Matlab for simulation.The resault promits that the clustering algorithm is effectively prolong the lifetime of the network.更多还原
