基于地理位置划分的无线传感器网络分簇算法

A Clustering Algorithm of Wireless Sensor Network Based on Geographical Division

利用分簇算法延长无线传感器网络的生命周期是一个研究热点。基于经典的LEACH路由算法,提出了改进:主要体现在对节点地理位置的划分和在成簇过程中考虑传感器节点的剩余能量以及簇头与非簇头之间的距离。最后用Matlab对LEACH算法和改进后的算法进行仿真,证实了改进后的算法在网络生存时间上比LEACH算法有了很大提高。

Using clustering algorithm to prolong the lifetime of wireless sensor network is an important issue. We propose an improvement about the classical LEACH. In the division of geography position and the clustering process the remaining energy of sensor nodes and the distance between head node and normal nodes are considered. At last we use the Matlab to simulate the classical LEACH and the improved algorithm. The results of the simulation prove that the lifetime of the improved algorithm is better.
