Investigation on End-to-End Congestion Control Algorithm in Multi-Hop Ad-Hoc Network

A multi-hop wireless network forms a formidable solution to overcome spectrum deficit and coverage issues in wireless conditions. As wireless internet remains crucial in connecting people from remote locations, a vast chunk of web traffic relies solely on Transmission Control Protocol (TCP) to deliver packets between end systems. In the paper, an initiative is made to analyze the traffic stability under a multi-hop wireless link. TCP manages congestion by adjusting the transmission window size. In this regard, two diverse end-to-end traffic or congestion control algorithms, i.e., linear and concave-based window growth patterns, are subjected to evolution in mobility, traffic, and error rate conditions. The traffic performance of the wireless network is measured with these algorithms using Network Simulator-3 (NS-3).
