The applications of sensor networks are getting critical and important particularly in strategic, applications such as corresponding target detection, surveillance, and target localization. To accomplish target detection and localization data from more then three sensors which receive signals from moving targets, measure RSSI, and translate RSSI into the distance between sensor and target. All this process involves more sensor and energy consumption, where as the energy is a critical resource in wireless sensor networks and network lifetime needs to be long-drawn-out through the use of energy-conscious sensing strategies during system operations.
