Abstract

In the multiple-event WSNs, each event has different importance and most of the congestions are caused by the burst events with high importance. Therefore, the priority-based congestion control algorithm is required to WSNs. Most of the existing algorithms to control the congestions of the WSNs do not consider the priorities of the events. In addition, the existing algorithms rely on the rate control of source nodes using the backpressure mechanism but it is not efficient for the dynamic applications (ex. Tracking application). Therefore, we proposed a new algorithm that uses the queue state management and duty-cycle adjustment. This new algorithm tries to prevent the congestion previously and adjusts the duty-cycle to guarantee the reliability of the important events. The simulation results show that the proposed algorithm performs better than the existing algorithm in both of the static case and dynamic case.
