The area of mobile ad hoc networking has gained widespread interest of the network research community in recent years because of the ability of the MANETs to provide truly distributed and decentralized communication facility on ad hoc basis. But due to the bandwidth constrained links and limited transmission range of the mobile nodes, MANETs suffer from the inability to cover a wider network area. 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. We have analyzed the performance differentials on the basis of three QOS parameters – packet delivery fraction, average end-to-end delay and normalized routing load under varying pause time with different number of sources.
