无线传感器网络中的LEACH算法分析与设计

Analysis and Design of LEACH Algorithm for Wireless Sensor Network

在分析了经典的LEACH分簇路由算法,以及基于LEACH算法基础上的几种经典的改进算法后,针对小规模无线测距网络的特点,在传输数据量较少、簇首节点无需进行大量数据融合的情况下,对LEACH算法进行改进,增加了节点与基站直接通信的个数,减少了多跳累加误差对测距的影响。使用MATLAB软件进行仿真,理论与实验仿真表明,本文提出的改进算法能够延长整个网络的生存时间,减少了一些不必要的能量浪费。

This paper analyzes the classic LEACH algorithm, and some classic clustering algorithms based on LEACH. Aiming at the small wireless sensor network, the data in the network is not much. Cluster head node doesn＇t need to fusion the data in the network. In this case, the LEACH algorithm is improved, the number of nodes with direct communication with base station is increased, and the accumulate error caused by multi-hops is reduced. Using MATLAB software, theoretical analysis and simulation results show it extends the network alive time, reducing some unnecessary energy waste.
