WBANs for live sport monitoring : an experimental approach, early results and perspectives

Abstract : In this paper we present a simple Body Area Network (BAN) platform that was built to monitor the performance of a marathon athlete all along the race, meeting real-time and QoS constraints, under good transmission conditions. Data collected during the event (packet loss, signal strength) allowed us to obtain a primary knowledge about the behavior of the radio transmissions between the different links in the network. The results of this experiment and the important disparities observed between the links point out the need to improve the transmission strategy.
