Abstract
Providing real-time data delivery in wireless sensor networks is a challenging research problem. In this paper we propose a centralized control plane incorporating the timed token protocol in the MAC layer for providing real-time data delivery in wireless sensor networks. In this approach hard real time guarantee is provided by a dynamic ring structure, where high priority stations have more chance of admittance and stations with low priority can be removed from the ring. Soft real time guarantee is provided by using proactive wireless routing protocol (DSDV) for path finding and maintenance, timely delivery of data is done through a prior bandwidth reservation. Simulation results show that the proposed control plane and bandwidth reservation ensures higher priority traffic more bandwidth than lower priority traffic and guarantees real-time data delivery.
