In Vehicular Ad hoc Networks (VANETs), access control and authentication are crucial security services for both vehicle to vehicle (V2V) and vehicle to infrastructure (V2I) communications. On the other hand, services provided by VANETs would be reduced if the vehicle private data are misused and the privacy is not protected. In this paper, we investigate the secure access control with authentication...
Recently, Visible Light Communication (VLC) has been proposed as a low-cost and low-complexity technology for vehicular communications. In this paper, we propose a vehicular network architecture that enables wireless Infrastructure-to-Vehicle (I2V) and Vehicle-to-Vehicle (V2V) communication to provide value added services. The wireless communication technique chosen to enable the data transmission...
Vehicle Ad-Hoc Network (VANET) applications are proposed in the literature to provide a certain degree of Quality of Service (QoS) to vehicles. Nevertheless, VANET experiences high mobility, dynamic topology and propagation irregularity. These characteristics make the QoS requirements in VANET a challenging issue. In this paper, we propose a novel VANET architecture along with quality of service metrics...
Services provided by vehicular Adhoc Networks (VANETs) would be impaired if faced to sybil attacks, by which malicious vehicles claim multiple identities at the same time. The prevention of these attacks, which could occur in or out of the Road Side Units (RSUs) coverage, is challenging, as it should meet a compromise between the ability to identify the real identity of the malicious vehicle, and...
Several solutions were proposed to address VoIP security and quality of service in mobile wireless networks. However, the two aspects were approached by the literature independently of each other. The issue becomes more important to address in the context of vehicular adhoc networks where vehicles are highly mobile and the SIP handover procedure may exhibit several security vulnerabilities. This paper...
A Vehicular Ad-Hoc Network (VANET) is a form of Mobile ad-hoc network, to provide communications among nearby vehicles and between vehicles and nearby fixed roadside equipment. The key operation in VANETs is the broadcast of messages. Its main goal is to improve safety and comfort for passengers, but it can also be used for commercial applications. In this latter case, it will be necessary to motivate...
