ABSTRACT
Wireless Sensor Network is a new branch of networking which has been widely used in multiple applications like area monitoring, agriculture, environmental monitoring etc. Different applications require different parameters like network topology, energy constraint, number of nodes, location of base station etc. Based on the features of nodes with limited battery life, people have done deep research in order to prolong the network life time. With the assumption putted in LEACH, a new Protocol has been proposed in this paper in which base station is kept mobile. The base station is moving in a to and fro motion, initially the node is kept far away from nodes then for each 100 round the base station increments from its position and reaches in between sensor nodes. For next 100 rounds it starts positioning to its original position. The simulation is done in MATLAB and found that the lifetime is improved in comparison with original LEACH.
