Understanding the Mobility Model of Wireless Body Sensor Networks

Mobility pattern plays an important role in designing the wireless body sensor networks (WBSN) and also would affect the performance of WBSN in health care application. This paper is the first attempt to investigate the mobility model in WBSN based on the existing mobility models in wireless data networks and ad hoc networks. We first briefly review the existing mobility models in related research areas such as wireless ad hoc network and cellular networks. Further, we propose a dedicated mobility model for wireless body sensor networks by concentrating on the unique characteristics of WBSN and finally study the effects of mobility on the performance of WBSN by simulation experiments
