Network of large number of sensor nodes can be used for military surveillance, habitat monitoring, vehicle tracking and infrastructure monitoring. Extending the lifetime of the wireless sensor network has been aimed by several research efforts. Distributed networks provide a viable solution to increase the lifetime of WSN. It does not assign the heavy task to a single node, which otherwise can result in the loss of connectivity, fast depletion of the battery of the single node and reallocation of the tasks. Task allocation in WSN play a major role in extending the lifetime.
