Performance Evaluation of TCP Reno and Vegas over different routing protocols for MANETs

In this paper, we investigate the effects of node's mobility on the throughput of TCP variants such as Reno and Vegas. Reno views the packet loss as signal of network congestion, while Vegas uses the difference in the expected and actual throughput rates as network congestion indicator. Simulation results from the implementation of different simulation scenarios using NS-2 over different routing protocol such as, Ad hoc On-demand Distance Vector (AODV) and Distance Sequence Distance Vector (DSDV) show the performance of TCP variants (Reno, Vegas) over AODV is better than DSDV.
