Abstract

In this paper, one of the most important issues supporting real-time QoS in wireless sensor networks is discussed, which is fundamentally a challenging problem. A novel MAC protocol based on dynamic priority scheduling is proposed for wireless sensor networks, whose packets competes media with a dynamic priority. Two different platforms based experiment projects including detailed hardware and software designs are designed to evaluate the proposed MAC protocol. Experiment results indicate that our proposal is more effective than hard real-time scheduling in resource-limited wireless sensor networks.
