An Adaptive Routing Mechanism for Wireless Body Area Network (WBAN)

Deploying bio-sensors on a human body to measure various biological signals of the body, to form a Wireless Body Area Network (WBAN). WBAN enables an efficient way to continuously monitor all the biological parameters of the body, even brain activities through implanted/body-worn devices. Wireless body sensors are a key technology for unobtrusive health monitoring. Automatically forming a wireless network comprising all sensors attached to the same body is challenging. Reliable communication between the sensors placed on various parts of the body is an important aspect. There is a necessity of a well designed communication for intra WBAN. This  paper  investigates the two  different network  topologies used for communication in Intra WBAN , star topology  and  multi-hop approach , then  proposes a new adaptive routing mechanism that automatically adapts the topology according to the connectivity  status of the network. Finally it evaluates the energy consumed by the Routing Mechanisms in WBAN. The simulations are carried out by Network Simulator 2.
