无线传感器网络LEACH协议的改进及仿真

The Improvement and Simulation of Wireless Sensor Network LEACH Protocol

随着网络的发展,无线传感器网络逐渐被应用于社会的各个方面。鉴于无线传感器具有能量有限性的特点,从硬件方面进行改进有一定的难度,所以就引出了无线传感器网络的路由协议,找到一个好的路由算法来延长无线传感器网络的生命周期。本文介绍了最典型的分簇路由协议LEACH协议及在LEACH路由协议算法缺点的基础上进行了改进的算法LEACH-C协议算法。从对两种路由协议的仿真结果来看,改进后的算法能够使各传感器节点的能量得到均衡,网络的负荷也相应得到了均衡,从而延长网络的生命周期。

With the development of the network, the wireless sensor network has been gradually applied to all aspects of the society.In view of the characteristics of energy limited of the wireless sensor, to improve hardware has certain difficulty.So it leads to a wireless sensor network routing protocol, which is finding a good routing algorithm to prolong the life cycle of wireless sensor network.This pa-per introduces the typical clustering routing protocol LEACH agreement and the improved algorithm LEACH-C protocol on the basis of overcoming shortcomings of LEACH.Judging from the simulation results of two kinds of routing protocol, the improved algorithm can balance the energy of each sensor, balance the network load and prolong the life cycle of the network.
