Mobile Ad hoc Network (MANET) in the form of wireless local area networks is becoming a common platform for communication among internet users. As compared with wired networks, the rate of random packet loss due to wireless channel errors or node mobility is very high in MANET. Misinterpretation of random packet loss as a loss due to congestion by TCP causes significant degradation in the performance (i.e. aggregate throughput) of the network. Numerous solutions are proposed in literature, but they either are cross layer solution or focused on specific issues of TCP. In order to improve the efficiency of TCP in dynamic mobile ad hoc network, we proposed a new energy efficient, end-to-end, layered, transport layer solution. The solution, referenced as “Proposed-TCP”, can identity packet loss due to congestion, wireless channel error and route failure, by using multiple end-to-end metrics. The solution can manage the incipient congestion in the network also. The solution is implemented and simulated in Network Simulator (NS2) for Gauss-Markov and Manhattan-Grid mobility models. The simulation results are collected carefully and compared with the results of TCP Reno, TCP Santa Cruz, and ADTCP. The simulation results show that the proposed solution outperforms TCP Reno, TCP Santa Cruz, and ADTCP by producing better performance in terms of throughput and fairness.
