Abstract

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, Efficient HRTC the basic design of HRTC is based on the fact that the conditions in WSNs are possible to change then and there. It is possible for a densely deployed network to initially exist, but after some time this to transform into a network full of routing holes or disconnected parts either due to network issues, like heavy traffic. In either case, the target of this work is to find a solution that maximizes the efficiency of the network in terms of throughput and lifetime, using effectively the available network resources. The application this congestion control methods is to reduce the congestion completely. Hence, we propose a hybrid algorithm that aims to exhibit only the positive advantage of both individual methods. In this algorithm, when a node faces congestion, it attempts to inform the source node from which it receives packets with the lowest data rate, to suppress its data rate. To achieve this, it transmits a BPM to the source. We choose to limit the transmission of the source node with the lowest data rate because we prefer to keep serving the nodes with higher data rate(s) in order to affect throughput the least. When BPM receives the source node it lower its data rate. In this paper there are three algorithms called traffic control (TC), resource control (RC) and advanced hybrid technique. These three parameters/ algorithms are used to control congestion in a wireless sensor networks.
