Performance of DSR Algorithm in VANETs

Abstract

Due to the low cost and wide availability of some mobile communication devices, wireless networks, such as Mobile Ad Hoc Networks (MANETs), can be built easily, affordable, and without the need of a physical infrastructure in a variety of scenarios and applications. For instance, when connecting vehicles on a road, these networks are called Vehicular Ad Hoc Networks (VANETs). The aim of this paper is to evaluate the Dynamic Source Routing (DSR)algorithm for VANETs. This study highlights the conditions necessary for packet transmission to devices that are not directly connected. Also, it is considered a scenario with distributed devices on a two-lane road, the use and the best disposition of relay poles, the required radio setting, and the use of different channels to increase network throughput. In addition, the shadowing propagation model is used. Index Terms-ad hoc, routing, DSR.
