Media-Aware Distributed Scheduling Over Wireless Body Sensor Networks

Distributed scheduling for hybrid media flows over wireless body sensor network faces three technical challenges: constrained communication channel, random node placement and strict transmission latency. In this paper, the authors study this problem by jointly considering the above three challenges to achieve the minimum media distortion and optimal network resource utilization. At first, they construct a general flow transmission model according to network's transmission mechanism, as well as media-aware flow's characteristics. Then, a distributed scheduling scheme is proposed based on dynamic network resource update.
