Wireless sensor networking is a network of wireless sensor nodes deployed in an area. Wireless Sensor Network (WSN) system is built on an IEEE 802.15.4 wireless mesh network. The wireless sensor network consists of the sensor nodes. A WSN is a wireless network using sensors to cooperatively monitor physical or environmental conditions such as humidity, pressure, temperature, sound and vibration. The reduction of energy overhead is a major challenge in wireless sensor networks. The idea of development of wireless sensor networks was initially motivated by military applications.
