Abstract

In this paper we describe a ns based simulation analysis of TCP performance over a hybrid network with first link as a wireless link. The latter choice is for understanding performance issues with better clarity. The effect of wireless errors on different TCP parameters resulted into end to end performance degradation of TCP is investigated. Based on the analysis of the basic MAC loss recovery mechanism, we are able to show impact of delay introduced by MAC loss recovery over the performance of TCP. With increased MAC loss recovery duration TCP is unable to conceive maximum of available bandwidth over a network. In addition, it also describe that adaption in CWND will improve the performance of wireless networks. All above simulation results clearly show a) scope for improving MAC loss recovery and b) requirement of tuning between TCP and MAC loss recovery, particularly for retransmission mechanism.
