Wireless sensor network is the latest area of research which is continuously becoming the hotspot topic due its wide range of applications where infrastructure based network are not feasible.But since the nodes of WSN are limited in battery so it is necessary to have proper routing protocols for saving energy and hence nowadays protocols using clusters are getting more concern by many researchers. In this paper, we have compared two cluster based routing protocols viz. LEACH and I-LEACH. Simulation results in terms various lifetime metrics(dead nodes,alive nodes, throughput of the network) are carried out and proved that I-LEACH always outperforms in comparison to LEACH.
