摘要：Vehicular ad-hoc network (VANET) is an integral component of intelligent transportation systems. Due to continuous movement of vehicles, network formation and de?formation is very frequent. Furthermore, for safety applications, we wish to create the communication without any delay or collision. Therefore, communication among the vehicles is even more challenging. D-LAR (Directional– Location Aided Routing) is one of the position based routing protocol which works efficiently in VANETs. We want to analyze the performance of D-LAR protocol in a city traffic scenario. To do a quality performance evaluation, extensive simulations has been done in realistic environment created with SUMOatraffic simulator and NS-2 network simulator. The performance of D-LAR protocol has been compared with LAR on various metrics like routing overhead, packet delivery ratio and delay.
