Performance Evaluation of TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) over Destination Sequence Distance Vector (DSDV) for Random Waypoint Mobility Model

A mobile Ad-hoc network (MANET) is a collection of wireless nodes aimed at information exchange and resource sharing. The Destination Sequence Distance Vector (DSDV) a well-known and widely used protocol for MANETs. This paper presents the comparative performance analysis of TCP and UDP (two transport layer protocols) over DSDV in a Mobile Ad hoc Network. Three performance metrics: throughput, end-to-end delay and packet loss parameters are used to evaluate the performance of TCP and UDP. A number of topology parameters are varied including node density, node speed and pause time. Simulations are performed using ns-2 which show that in general TCP traffic outperforms UDP traffic for DSDV. UDP flows perform better in the case of dense networks with little or no mobility. TCP flows perform better for high mobility scenarios.
