Performance Analysis of TCP for Various Mobile ADHOC Routing Protocol

In this paper the performance of the TCP over different Mobile Ad-hoc Routing Protocols is evaluated by using the network simulator (NS2). The routing protocols used in the simulations are Ad-hoc On Demand Distance Vector Routing protocol (AODV), Dynamic Source Routing protocol (DSR) and Destination Sequenced Distance Vector routing protocol (DSDV). The DSDV is a table driven algorithm. DSR is source routing algorithm i.e. source appends the complete route for the packet to reach the destination in the packet’s header. AODV is an on demand routing protocol. To analyze the performance of TCP over routing protocols MANET the TCP through put and TCP window size are obtained from simulations. The simulations are performed for the three routing protocols (i.e. AODV, DSDV and DSR) for the different mobility rates. By comparing the TCP throughput and TCP window size for different routing protocols at different mobility rates, the performance of the TCP for different mobile Ad-hoc Routing protocols is evaluated.
