Recently, security and privacy have been one of the main concerns that impedes the development of vehicular ad hoc networks (VANETs). In this paper, we put forward an access control with authentication scheme for disseminated messages in VANETs. In the scheme, we integrate pseudonym with identity based signature (IBS) which could not only authenticate the messages in vehicular communication, bu...

Proper selection of a simulator for VANETs is a serious task. Due consideration has to be given to the requirements for modeling the behaviour of networking protocols and mobility of vehicles. Both macro and micro aspects are important for evaluation of the traffic behaviour. Macro aspects are road conditions and infrastructure, while micro aspects constitute individual behaviour such as drivin...

----------------------------------------------------------------------ABSTRACT--------------------------------------------------------------Vehicular Ad-hoc Networks (VANETs) have been recently attracting an increasing attention from both research and industry communities. VANETs are currently deployed on a large scale, research in this area is mostly simulation based. Mobility models or the mo...

Vehicular Ad hoc NETworks (VANETs) have emerged as a platform to support intelligent inter-vehicle communication and improve traffic safety and performance. The road-constrained, high mobility of vehicles, their unbounded power source, and the emergence of roadside wireless infrastructures make VANETs a challenging research topic. A key to the development of protocols for inter-vehicle communic...

Due to the development of communication and other related technologies, vehicular ad hoc networks (VANET) have been experiencing a rapid development in the recent years. Clustering has been proved an effective way to manage the wireless resource, control the network topology, and simplify the routing in VANETs. However, it is difficult to construct stable clusters in VANETs, because of the high...

Vehicular ad-hoc networks (VANETs) offer a large number of new potential applications without relying on significant infrastructure. Many of these applications benefit from multi-hop relaying of information, thus requiring a routing protocol. Characteristics unique to VANETs (such as high mobility and the need for geographical addressing) make many conventional ad hoc routing protocols unsuitab...

Vehicular Ad Hoc Network (VANET) is a subgroup of mobile ad hoc network (MANET). It is an emerging new technology to exchange information between vehicles to vehicles. VANETs are considered as one of the most noticeable technologies for improving the efficiency and safety of transportation systems. VANET mainly used to exchange traffic information between the vehicles and prevent accident. In V...

VANETs are the vehicular networks used to connect the vehicles together to share their information with each other in the cluster. The hackers are used to attack VANETs with various means of attacks. Many security techniques are used to mitigate the risks caused by the attacks to cause ill-effects to the traffic movement on the roads. VANETs are also being used for the automatically driven vehi...

Vehicular Ad Hoc Networks (VANETs) are considered as a special case of mobile Ad Hoc Networks (MANETs) and are recently gaining a great attention from the research community. The need for improved road safety, traffic efficiency and direct communication along with the great complexity in routing, makes VANETs a highly challenging field.. Routing in VANETs has to adapt to special characteristics...
