Comparative performance evaluation of routing algorithms in IEEE 802.11 Ad Hoc networks

In this paper we examine the behavior of ad hoc networks through simulations, using different routing protocols and various topologies. We examine the difference in performance, using a CBR application, with packets of different size through a variety of topologies, showing that the way nodes are placed in a network has an impact in networks performance. We show that the choice of routing protocol plays an important role on network´s performance. We also quantify node mobility effects, by looking into both static and fully mobile configurations. Our paper presents a systematic analysis of a variety of different ad hoc network topologies in terms of node placement, node mobility and routing protocols through several simulated scenarios.
