Performance Parameter Analysis of Congestion Control in Wireless Sensor Networks

Congestion control has been witnessed as most pervasive problem in the literature for design and development of Wireless Sensor Networks(WSNs). The most obvious reason of congestion occurrence in WSNs is resource constraints in terms of information processing, storage space, transmission bandwidth and most importantly power supply. To cope effectively with this problem, researchers need to model energy-aware protocols and algorithms along with taking into account different networking parameters such as throughput, reliability, fairness, packet loss ratio, etc. to ensure quality of service. In this research article, we have provided a comprehensive analysis of performance parameters considered by researchers and programmers while designing congestion control algorithms in wireless sensor networks, and their effect on the performance of algorithms. Unlike past studies we have not only considered classical approaches but also analyzed novel soft computing based approaches. It is logical intellection to take a holistic view and study the performance metrics of both the approaches of congestion control so that it would be useful for improving algorithms and further directions in the field of WSNs.
