Feedback Congestion Control Protocol for Wireless Sensor Networks: A Review

We have put forward some new ideas and congestion restriction algorithm for sensor networks based on feedback restriction, which will be known as Feedback Congestion Control (FBCC). This algo has been planned by making full use of linear discrete time control concept. A feedback control system is set up between parent and children node. The FBCC discover the beginning of congestion by using queue distance. An active steady control plan selects appropriate incoming traffic which is forced by the new active scheme. Encircled-loop stability of the proposed hop-by-hop congestion control is given by the Lyapunov-based approach. Simulation final conclusion show that the FBCC restricts congestion and makes better performance over Congestion Detection and Avoidance (CODA). The results of simulations proves FBCC can avoid and makes Congestion less severe and has fairly good effects of reliability, less energy consumption and high throughout.
