A congestion control protocol for wireless sensor networks

Abstract

In Wireless Sensor Networks (WSNs), the congestion can increase the ratio of packet loss and reduce of the network throughput. In this paper, I study on the congestion problem between child and parent nodes in WSN, which typically faces of low power and resource constraint devices. I use game theory strategy to design a parent-change procedure which decides how nodes changing their next hop node to mitigate the effect of network congestion. The simulation results show that the protocol can achieve improvement in packet loss rate and throughput.
