Vehicle Ad Hoc Network (VANET): Safety Benefits and Security Challenges

Abstract

The promise of safe driving, intelligent traffic system, early warning signals for motorists that could minimize road mishaps, increase road conditions advisement, and provision of better in-transit communication, inter-vehicle communication, and road-vehicle communication are some of the hallmark of vehicle ad hoc network (VANET). Conversely, the network’s challenges lie on its capacity for information system confidentiality (the prevention of unauthorized disclosure), integrity (the prevention of the unauthorized modification), availability (the prevention of unauthorized suppression of data or resources), stable communication in the presence of highly mobile nodes, and privacy concerns. This paper explored the network’s characteristics, architecture, application, communication patterns, security concerns, as well as identification of current development direction of the technology.
