Performance evaluation of topology based routing protocols for VANETs in urban scenarios

Vehicular Ad hoc NETworks (VANETs) are self-organizing ad hoc networks that are specifically designed for communication among vehicles. Although routing protocols have already been analyzed and compared in the past for Mobile Ad hoc Networks (MANETs), simulations and comparisons of routing protocols for VANETs have almost always been done considering random motions with non-urban specific parameters. This paper studies the performance of Ad hoc On-Demand Distance Vector (AODV), Destination Sequenced Distance Vector (DSDV) and Dynamic Source Routing (DSR) which are popular routing protocols for routing among vehicular nodes in VANETs. The effects of urban motions on the simulation parameters, their consequences on routing performance are compared between the three protocols in this study.
