Abstract
Mobile Ad-hoc Network (MANET) is a collection of mobile nodes which can self-organize freely and dynamically into arbitrary and temporary network topologies. Mobile nodes in ad-hoc networks can dynamically establish routes among themselves by means of a routing protocol. Therefore, selection of an appropriate routing protocol is an integral part of establishing a MANET. Apart from the choice of routing protocol, nodes present in the network (node density) and their level of mobility (node mobility) also affect the performance of the network. In this paper, we have studied and analyzed the impact of variations in node velocity and node density combined with the choice of routing protocol, on network performance. We have selected Destination-Sequenced Distance Vector (DSDV) which is a proactive routing protocol, and Dynamic Source Routing (DSR) which is a reactive routing protocol, for our study. The network performance is measured in terms of Packet Delivery Ratio (PDR), End-to-End Delay and Throughput. The simulations are carried out in NS2.34.
