A Wireless Sensor Network consists of large number of sensor nodes possessing the ability of sensing, computing and transmitting data from the harsh environment. The sensor node closer to the sink has to forward the data of the farther nodes along with its own. As a result of which the nodes lying near to the sink gets depleted in terms of energy than the other nodes which are lying farther from the sink. It results in network isolation or results in HOT SPOT problem.
