Congestion Aware Fair Data Delivery in Wireless Multimedia Sensor Networks

In this paper we present a novel energy efficient congestion control scheme for Wireless Multimedia Sensor Network called, CFD (Congestion aware Fair Data delivery). In our proposed CFD mechanism both node level and link level congestions are detected. It ensures fairness of each packet when packet drops happens due to congestion. To avoid congestion a fair rate allocation mechanism is also proposed. CFD has been evaluated extensively using simulations, and the results have shown that CFD provides a better performance with minimum delay than those of existing approaches.
