Wireless sensor networks have turn out to be an explorative area of research since last few years, due to energy constraints of sensors. Reduction of energy is a vital part of the research in this field. Congestion control is a key problem in mobile ad-hoc and sensor networks. In case of congestion system require more power to deliver data. Congestion leads to transmission delay, packet loss, and wastes time and energy for congestion recovery. This congestion leads to indiscriminate dropping of data, i.e. data of high importance might be dropped while others of less importance are delivered.
