A Systematic Approach for Congestion Control in Wireless Ad Hoc Network Using Opnet
Transmission Control Protocol (TCP) is a reliable, end-to-end transport protocol, which is most widely used for data services and is very efficient for wired networks. However, experiments and research showed that TCP's congestion control algorithm performs very poorly over Wireless Ad Hoc Networks with degraded throughputs and severe unfairness among flows. In this paper, a deep study has been conducted in order to study the factors that cause congestion in an ad hoc wireless network. The authors' main focus in this report has been to simulate and study the effect of change in topology and number of users on network congestion.
