Congestion is always a critical area to be tackled to prevent hindrance in successful communication between networks. Sharing of critical information is the foremost responsibility of assorted components of network. Due to sudden occurrence of congestion, all nodes in the Wireless sensor network have to work hard and more in retransmitting data packets to base station through intermediate sensor nodes due to their huge loss. Extreme energy consumption is also there which degrades all over performance and sometimes showing concomitant effects like packet loss in network. So, this congestion needs to be avoided to prevent network failure by improved design of Wireless sensor Network and making use of different congestion protocols as per the application in which it is required. In this paper, we will compare different congestion detection and control algorithms on the basis of protocols and parameters incorporate by them in their Wireless Sensor Network’s topology to handle congestions.
