In wireless sensor networks, the energy of the sensor nodes is limited. Due to the battery driven nature of the wireless sensor networks, the efficient utilization of power is essential. Deployment of sensor node in wireless sensor network is also important issue. If nodes are not properly deployed, a dense network will lead more number of packet collision and traffic jamming. If nodes are not well deployed then the authors cannot get proper information. Energy efficiency of wireless sensor network also depends on deployment of sensor nodes in network area.
