In WSN, usually tens or thousands of sensor nodes are deployed, scattered way in an area with one or more sinks. Moreover, for achieving reliability and load balancing, several multipath routing protocols have been proposed. But the limitation of these protocols is traffic overhead. Thus the occurrence of congestion in this situation is more likely. The situation becomes worse when congestion occurs in multiple paths. In order to achieve the desired rate of heterogeneous traffic by the sink the congestion control over multiple paths is indispensable.
