HRTC: A Hybrid Algorithm for Efficient Congestion Control in Wireless Sensor Networks

As applications in Wireless Sensor Networks (WSNs) are evolving, congestion control remains an open and, in several cases, a critical problem. A lot of research has been performed on this issue and two general approaches seem to be the most prominent for its solution: traffic control and resource control. Each of these two methods present specific advantages and disadvantages under different scenarios. In this paper we present HRTC, a dynamic scheme capable of bridging these two methods for congestion control and provide the best solution, based on the prevalent network conditions.
