What is Resource Scheduling Based on Priority Ladders for Multiple Performance Requirements in Wireless Body Area Networks about?

Media access control (MAC) plays a pivotal role in ensuring proper operation in wireless body area networks (WBANs). However, current solutions still cannot satisfy multiple requirements of such networks. In this article, we propose a priority ladders-based resource scheduling (PLRS) scheme to satisfy these requirements. First, we design a multiple-level priority division approach, which is based on the health parameters and the monitored data type of the patient. Unlike only two priorities of nodes in other schemes, there are four priorities in our solution. This priority division does not only match the practical situation, but also leads to more fairness among different nodes. Furthermore, we devise a ladders-based timeslot allocation method, in which time slots of nodes are increased round by round based on the priority ladders of nodes. This reduces the difference of the number of time slots between disparate nodes with close priorities, and accordingly enhances the fairness of nodes. In addition, we develop an interval-based transmission sequence design approach, in which nodes use the allocated time slots in dispersed multiple intervals rather than a continuous time span in
