Congestion has been considered as one of the basic issues in networks. The ultimate motto of congestion control remains very same for also type of communication networks. But the workings of congestion control techniques differ with respect to communication technologies. The difference between congestion avoidance and congestion control are explained. Congestion avoidance schemes like choke packet, probe packet, increase in cost, piggyback and acknowledgement schemes are studied in this paper. Efficiency, responsiveness, convergence, fairness, robustness and simplicity are discussed as a part of performance metrics. Importance of decision function, increase and decrease algorithms are discussed as congestion avoidance schemes. These schemes are demonstrated with shared paths, heterogeneous routers, and different workloads of data. The main goal of this paper is to make an overview of the existing congestion control techniques for constrained environment and propose a need for the development of new flexible technique. It has addressed all restrictions set by the environment and at the same time be generic enough.Read More
