Wireless sensor network (WSN) plays a major role in the modern world. It is a useful technology for sending and receiving data from several parts of the system using mini sensor nodes that are distributed over a wide area. These nodes are capable of performing several data operations like sensing the environment, gathering, processing the data and other operations. They receive the essential energy for performing these processes from the batteries embedded in these nodes. In many applications, the sensor nodes are small equipped with a small size battery of little energy. It is very important to reduce energy consumption and to make the lifetime of the network as long as possible. For this purpose, the Low Energy Adaptive Clustering Hierarchy (LEACH) routing protocol has been developed. In this paper, a modified model of LEACH protocol is developed to further reduce energy consumption and consequently, increasing the lifetime of the network.
