Hop count and delay analysis of D-LAR protocol for VANET

摘要

Vehicular ad-hoc network (VANET) is an integral component of intelligent transportation systems (ITS). Due to frequent speed variations of vehicles, network formation and deformation 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. Its performance has been compared with LAR protocol for various metrics like routing overhead and delay. To do a quality performance evaluation, extensive simulations has been done in realistic environment created with SUMO a traffic simulator and NS-2 network simulator.
