The Impact of Propagation Models in the Performance of Ad Hoc Routing Protocols for Urban VANET

Different researches for Intelligent Transportation System evaluated the performance of Ad hoc routing protocols for vehicular networks. Nevertheless, most of them are not realistic for vehicular network neither for urban environment, limiting their results accuracy. The aim of this paper is to compare the performance impact of ad hoc routing protocols (e.g. AODV, DSR, DYMO and OLSR), under different propagation models (Free Space, Two Ray Ground, Nakagami and Log Normal) in a real urban map. The evaluated metrics were the Packet Delivery Rate and the End-to-End Delay under Omnet++ and SUMO simulators. The contribution of this work concerns the configuration and evaluation of a real vehicular scenario in a urban environment to be the basis of future researchers, to help them to know how will be the response of routing protocols applied in different propagation model.
