        A Proxy Acknowledgement Mechanism for TCP Variants in Mobile Ad Hoc Networks

        Oo, May Zin,Othman, Mazliza,O'Farrell, Timothy The Korea Institute of Information and Commucation 2016 Journal of communications and networks Vol.18 No.2

        A sequence number checking technique is proposed to improve the performance of TCP connections in mobile ad hoc networks. While a TCP connection is initialized, a routing protocol takes the responsibility for checking the hop count between a source and destination pair. If the hop count is greater than a predefined value, the routing protocol decides to use a proxy node. The responsibility of a proxy node is to check the correctness of data packets and inform the missing packets by sending an acknowledgement from a proxy node to the source node. By doing so, the source node is able to retransmit any missing packet in advance without waiting until an end-to-end acknowledgement is received from the destination. Simulation results show that the proposed mechanism is able to increase throughput up to 55% in static network and decrease routing overhead up to 95%in mobile network.
