TCP Performance through Simulation and Testbed in Multi-Hop Mobile Ad hoc Network

When a packet is sent through wireless network it can be lost due to either environmental noise or due to congestion in the network. Traditional TCP protocols do not perform well in the wireless network because they were designed for wired networks with the assumption that the transmission medium is quite reliable. This often results in TCP's failure in distinguishing the cause of the packet loss as most of these problems hinder the throughput of the TCP connections in wireless networks. The work has been carried out to test the window size, packet size and path length of Multi-Hop Ad hoc Network, the TCP performance in a straight line, multi hop ad-hoc networks in two ways: the first one network simulator ns-2 and second one practical testbed, and the results that were obtained from both the models were compared and analyzed.
