Time multiplexing-star shape body sensor network for sports applications

Health and sport applications have been a flourishing area for deploying Wireless Body Area Networks (WBAN) as this technology can provide a real time feedback which is important for the user, coaches, doctors and the viewing public. This paper presents the wireless channel reliability and efficiency for time multiplexing and star shape body area network operating on 2.45GHz with a data rate of 1Mbps. The network employs sensor locations on both arms and legs of the human participant to sense and send acceleration data during the course of running. The results show a tradeoff between the channel occupancy and traffic generated to provide high channel reliability for the body network.
