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 paper, we propose to improve SEP by fuzzy logic (SEP-FL). We show by simulation in MATLAB that the proposed method increases the stability period and decreases the instability of the sensor network compared with LEACH, LEACH-FL and SEP taki

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
