Coexistence improvement of wearable body area network (WBAN) in medical environment

Wireless body area network (WBAN) witness an upward interest in several domain. Mainly, the medical domain takes advantages from the health service facility, the high flexibility and the mobility. However, interferences from coexisting wireless networks may lose critical informations and greatly affect on network reliability. In this paper, we are conducting to improve coexistence between WBAN based IEEE 802.15.4 protocol and WIFI. We adopt multi-hop routing to ensure reliability, connectivity and battery life. Then we investigate different effects of transmit power, transmission frequency and packet size on WBAN performances under heavy and real interferences circumstances. We propose a well suited model and simple adaptive algorithm which adjust dynamically its parameters with received performances indicators.
