WSN LEACH based protocols: A structural analysis

Abstract

The Researchers and the actual users had given much attention to Wireless sensor networks (WSNs). The energy utilization in these wireless sensor networks is very important task that increases the lifetime of the sensor network. In WSNs the researchers had explored numerous new protocols by considering the energy utilization as crucial task. Although, we have so many WSN protocols, but the importance is given to clustering based hierarchal routing protocols because of their better scalability. The sensor nodes are generally battery-powered devices, the important task in WSN is to reduce the energy consumption of nodes so that the life time of the network can be increased. Among the all present energy efficient Sensor networks protocols, the most common is LEACH. All other protocols are developed by taking the LEACH as reference. In this paper, we had analyzed the various LEACH Based protocols.
