Modified LEACH Algorithm for Prolongation Network Lifetime in Wireless Sensor Network

Wireless sensor network (WSNs) composed from a large number of sensor node with the ability to sense and process data in the physical world in a timely manner. The sensor nodes contain a battery constraint which limit the network lifetime. Due to energy constraints, the deployment of WSNs will required advance techniques to maintain the network lifetime. A clustering based routing algorithm called Low-Energy Adaptive Clustering Hierarchy (LEACH) was proposed as a solution for power consumption. This paper studies LEACH protocol, but some modification needed because of deficiencies in LEACH protocol. Simulation result shows that modified LEACH algorithm prolong the network lifetime.
