Abstract
In a Mobile Ad Hoc Network (MANET), temporary link failures and route changes happen frequently. With the assumption that all packet losses are due to congestion, TCP performs poorly in such an environment. Most of the research performed for improving TCP performance over MANET requires feedback from the network or the lower layer. Moreover, several attempts have been proposed for a layered TCP improvement. Yet, their percentage enhancements are not satisfactory. In this paper, we explore a new approach to improve TCP performance. This approach depends on beginning transmission as soon as route reestablishment is done after route failure. To do this we propose an adaptive backoff strategy with decreasing congestion window and slow start threshold values when we receive acknowledgement from the receiver. The simulation results showed that this approach had achieved an average performance improvement of 17%. Moreover, the proposed technique does not require feedback from the network or the lower layers.
