Wireless sensor networks (WSNs) are getting in a wide range of applications, such as mart homes, military surveillance, habitat monitoring, and precision agriculture. Sensor node placement is the most challenging problem in wireless sensor network due to the limited battery power. For critical applications, sensor node placement in efficient way is necessary to monitor the event precisely, which alternatively achieve balance energy depletion and extend the network lifetime. In multi-hop transmission, nodes lies in sink vicinity have heavier traffic loads which deplete their energy quickly; this leads to energy holes around the sink, which ends network lifetime. However, most of sensor nodes have enough residual energy in network. This paper presents corona based sensor node deployment strategies and their effect on residual energy has been showed. Simulation result shows residual energy of each corona during network lifetime.
