Wireless communication protocol based on EDF for wireless body sensor networks

Abstract

This paper presents a wireless communication protocol based on the Earliest Deadline First policy for wireless body sensor networks. This work advances a previous effort by proposing using an implicit Earliest Deadline First policy to guarantee real-time communication by optimizing network traffic flow, although this strategy may imply using the totality of bandwidth resources. The proposed protocol uses a slotted time-triggered medium access transmission control that is collision-free, even in the presence of hidden nodes. The protocol has been analytically modeled using Colored Petri Networks and Simulated in OPNET.
