Abstract: In wireless sensors networks (WSN), huge number of nodes are deployed randomly in area for analysing the environment conditions at that time like temperature, light, earthquake, humidity, sound etc. & transmit their sensed or measured data to sink nodes by means of multi hopping data transmission process. The sensor nodes relay on limited battery life where as sink nodes are always rich power because they are connected at back end network. During the data transmission, the sensor nodes which are closer to sink nodes use up their energy earlier than the nodes which are away because they relay more data packets. It means some sensor nodes are burn out and some are alive. This cause to energy imbalance in between the sensor nodes, and leads to connectivity holes and coverage holes, and finally there is whole network failure.
