Abstract: Mobile Multi-hop Ad Hoc Networks are collections of mobile nodes connected together over a wireless medium. These nodes can freely and dynamically self-organize into arbitrary and temporary, ad-hoc network topologies, allowing people and devices to seamlessly internetwork in areas with no pre-existing communication infrastructure. It is, however, possible to combine an infrastructure-less ad hoc network with a fixed one to form a hybrid network which can cover a wider area with the advantage of having less fixed infrastructure. Due to the hybrid nature of these networks, routing is considered a challenging task. Several routing protocols have been proposed and tested under various traffic conditions. However, the simulations of such routing protocols usually do not consider the hybrid network scenario. In this work we have carried out a systematic simulation based performance analysis of the two prominent routing protocols: Destination Sequenced Distance Vector Routing (DSDV) and Dynamic Source Routing (DSR) protocols in the hybrid networking environment using NS2. The performance of the DSDV is better than the performance of the DSR routing protocol. To compare the performance of DSDV and DSR routing protocol, the simulation results were analyzed by graphical manner and trace file based on Quality of Service (QOS) metrics: such as , packet delivery fraction, average end-to-end delay and normalized routing load under varying pause time with different number of sources.
