Recent advances in wireless sensor networks have settled into an important part of one's everyday life and gained attention from both the research community and actual users. In wireless sensor networks energy alertness is an essential consideration & it explored to many new protocols specifically designed for sensor networks. Most of rank, given to hierarchical routing protocols based on clustering because of scalability. In this paper the authors analyze the routing challenges & design issues involved in the wireless sensor networks and present the overall working of leach protocol and its simulation.
