ABSTRACT

We describe a variant of TCP (Tahoe, Vegas), TCP is most widely used transport protocol in both wired and wireless networks. In mobile ad hoc networks, the topology changes frequently due to mobile nodes, this leads to significant packet losses and network throughput degradation. This is due to the fact that TCP fails to distinguish the path failure and network congestion. In this paper, the performances of TCP over different routing (DSR, AODV and DSDV) protocols in ad hoc networks was studied by simulation experiments and results are reported.
