Comparative Performance Analysis of DSDV and AODV Routing Protocols in MANET using NS2

A Mobile Ad hoc NETwork (MANET) is a kind of wireless ad-hoc network, and is a self configuring network of mobile routers (and associated hosts) connected by wireless links – the union of which forms an arbitrary topology. The routers are free to move randomly and organize themselves arbitrarily, thus the network's wireless topology may change rapidly and unpredictably. Such a network may operate in a standalone fashion, or may be connected to the larger Internet. There are various routing protocols available for MANETs. The most popular ones are DSR, AODV and DSDV. This paper examines two routing protocols for mobile ad hoc networks– the Destination Sequenced Distance Vector (DSDV), the table- driven protocol and the Ad hoc On- Demand Distance Vector routing (AODV), an On –Demand protocol and evaluates both protocols based on packet delivery ratio, Jitter, and control overhead while varying number of nodes and mobility speed. It is seen  that AODV indicating its highest efficiency and performance under high mobility than DSDV, and the performance of TCP and UDP packets with respect to the Jitter, Control Overhead and PDR, and the performance of AODV is better than DSDV routing protocol for real time applications from the simulation results. A network simulator-2 (NS-2) called MobiREAL simulator has been designed and developed for performance evaluation of AODV and DSDV routing protocol in this paper.  The simulation result analysis verifies the DSDV and AODV routing protocol performances.
