To ensure fair bandwidth sharing between multiple sources sharing the same link congestion control is an essential mechanism at the transport layer to regulate traffic flows for bandwidth consumption. Congestion control is the main factor in maintaining the QoS for the wireless sensors networks. WSN are the ad hoc networks which once deployed in a particular environment to monitor specific physical phenomena are very difficult to maintain the QoS requirement throughout the network life time. So, very sophisticated and adaptive algorithms are needed to maintain the QoS requirement of the network.
