介绍WSN中非常重要的一种协议LEACH以及它的演化版本LEACH-C，是该领域的奠基性文章。-WSN introduce a very important LEACH protocol, as well as its evolution version of LEACH-C, are the foundation of the field article.

In our work we extend the LEACH s cluster head selection algorithm in WSN based on different node characteristics like, density, centrality and energy. This paper focuses on increasing the lifetime of wireless sensor networks.

this ppt describes the implementation procedure of leach protocol using matlab.
