An Analytical Study of LEACH Routing Protocol for Wireless Sensor Network

The use of low power sensor nodes to collect useful sensing information effectively is critical for any wireless sensor network (WSN) application to last longer. To increase network lifetime, energy consumption is considered as one of an essential performance metric. Most of the current proposed routing protocols proposed to reduce the amount of energy consumed and to increase the network lifetime. The common pioneer hierarchical routing protocol for wsn such as Low Energy Adaptive Cluster Hierarchical Routing (LEACH) is also proposed to improve the energy efficiency of WSN. LEACH is a cluster based routing protocol in which sensor nodes are combined together to form separate clusters and every cluster has a leader node named cluster head (CH). In this paper, we have done the analytical study of LEACH protocol to identify to what extent LEACH protocol can perform in terms of average energy consumption and packet loss for different data rate.
