Priority Node-Based Congestion Control Algorithm for Wireless Sensor Networks

In order to ease congestion phenomenon in the case of limited resources of nodes, this paper presents an adaptive congestion control algorithm based on the node´s priority. The proposed algorithm confirms prioritization according to the degree of congestion situation, and then adaptively chooses its probability of accessing channel in order to quickly relieve the congestion in this region. Experimental simulation results indicate that the algorithm can quickly and effectively to relieve the congestion and improve performance of network.
