Interest in vehicular ad hoc networks (VANETs) has grown over the last few years, particularly in the context of emerging intelligent transportation systems (ITS). Vehicular ad hoc networks (VANETs) are highly mobile wireless networks that are designed to support vehicular safety, traffic monitoring, and other commercial applications. However, efficient routing in VANETs remains challenging for...

Vehicular ad-hoc networks (VANETs) have been gained importance for the inter-vehicle communication that supports local communication between vehicles without any expensive infrastructure and considerable configuration efforts. How to provide light-weight and scalable location management service which facilitates geographic routing in VANETs remains a fundamental issue. In this paper we will pre...

Sybil attacks have become a serious threat as they can affect the functionality of VANETs (Vehicular Ad Hoc Networks). This paper presents a method for detecting such attacks in VANETs based on distributed data fusion. An algorithm has been developed in order to build distributed confidence over the network under the belief function framework. Our approach has been validated by simulation.

A Vehicular Ad-Hoc Networks (VANETs) are technology that uses moving cars as nodes in a network to create a mobile network. VANET turns every participating car into a wireless router, allowing cars of each other to connect and create a network with a wide range. VANETs are developed for enhancing the driving safety and comfort of automotive users. The VANETs can provide wide variety of services...

Vehicular ad hoc networks (VANETs) have attracted much attention over the last few years. VANETs own several significant characteristics, such as the high-rate changing topology led by velocity of vehicles, time-and-location critical safety applications, and Global Positioning System (GPS) devices. In VANETs, as vehicle movement is usually restricted in just bidirectional movements along the ro...

Vehicular Ad-hoc network consists of wireless mobile nodes which form a temporary network having no centralized infrastructure. VANETs have dynamic topology because of higher node mobility. VANETs provide benefits like road safety, security etc of vehicles etc Therefore, reliable and efficient routing is one of the main challenges in VANETs. Many improved routing algorithms have been implemente...

In this paper we discuss misbehavior detection for vehicular ad-hoc networks (VANETs), a special case of cyber-physical systems (CPSs). We evaluate the suitability of existing PKI approaches for insider misbehavior detection and propose a classification for novel detection schemes. Cyber-physical systems (CPSs) are digital systems that are closely embedded into the physical world with which the...

The successful deployment of vehicular ad hoc networks (VANETs) has to overcome the serious security threats which impair the operation of different vehicular applications. This paper presents the vulnerabilities of vehicular ad hoc networks and analyzes some of the security problems inherent in VANETs and also presents proposed solutions to overcome some of the vulnerabilities and security pro...

Privacy and security are very important in vehicular ad hoc networks (VANETs). VANETs are negatively affected by any malicious user’s behaviors, such as bogus information and replay attacks on the disseminated messages. Among various security threats, privacy preservation is one of the new challenges of protecting users’ private information. Existing authentication protocols to secure VANETs ra...
