A systematic classification of routing in vehicular ad hoc networks

Abstract

Vehicle ad hoc network (VANET) is a promising aspect in intelligent transportation system (ITS) which is getting considerable attention from researchers. In this vehicles formulate a self-organized network with an aim to provide better traffic safety as well as enhance the travelling comfort for the commuters. VANET does not depend upon fixed infrastructure. In contrast to MANETs, the node positions in VANETs keep on changing very rapidly thus it becomes a big challenge to route the information to its destination. In this paper we have surveyed different aspects highlighting architecture, applications, communication technologies, routing protocols, mobility models & simulating tools of VANETs. Finally some research gaps are listed which if addressed can result in an improved overall driving experience.
