An Overview on Wireless Body Area Networks

Wireless body Area Network is the interconnection of multiple nodes that are located in or around the surface of the body which is capable of wireless communication. Wireless body Area Network involves various monitoring application environment, warfare, agriculture, military and health care. The sensor nodes are usually light weight, low cost, low power consuming intelligence devices which are capable of sensing, computing, communicating with each other wirelessly. This review gives a clear overview about the functions of WBAN. The main operation of protocols, transmitter and receiver of IEEE 802.15.6 are deeply examined and studied in this work. This survey paper provides quick summary about the sensor design, applications, power efficiency, energy conservation, communication protocols and security issues in WBAN.
