Inter-vehicle communication (IVC) and its diverse application possibilities are experiencing growing interest both in research and industry. The dissemination of active safety messages generated by context-sensitive applications in Vehicular Ad Hoc Networks (VANETs) promises to improve passenger safety and comfort. A key challenge in such a scenario is to design an efficient broadcast protocol that...
This paper focuses on the characterization of vehicle mobility in vehicular ad hoc networks (VANETs). The performance of vehicle mobility in terms of link available time and the number of inter-vehicle link changes for maintaining active links in VANET is analyzed using both the handover and random moving models. The theoretical analysis is verified by simulation experiments. The numerical results...
Communications through road side units in Vehicular Ad hoc Networks (VANETs) can be used to track the location of vehicles, which makes serious threat on users' privacy. In this paper, we propose and evaluate a novel location privacy enhancement protocol for VANETs. Firstly, we propose an Anonymous Online Service Access (AOSA) protocol. Secondly, we analytically evaluate the anonymity and the unlinkability...
