چکیده
Wireless Body Area Networks (WBANs) have recently emerged as a solution to enable effective location-aware applications. The rapid mobility of nodes is the most specific problem of this kind of networks and it is not well considered when designing MAC protocols. In this paper, we consider a WBAN using a typical TDMA-based Medium Access Control (MAC) protocol and an Impulse Radio Ultra Wideband (IR-UWB) physical layer defined by the standard IEEE802.15.6. We investigate the impact of mobility on the Motion Capture applications. The Root Mean Square Error (RMSE) of the estimated positions is analyzed according to different scheduling strategies at MAC layer under a real human mobility model. Our results show that an effective scheduling scheme leads to prioritize the own node position estimation. Finally, we propose to extend the study with a realistic human body channel.
