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.

in this file, modified leach is there. Inwhich cluster head not directly send data to base station. instead of it, it send data to nearer node of cluster which is also nearer to base station. so it save clster head energy and this way extend the life
