Past few decades have witnessed large increase in number of vehicles on roads due to which the traffic safety needs have also become complex and hence necessary to be taken care of. Vehicular ad hoc networks (VANETs) are becoming an asset for achieving all these goals. VANETs provide applications like driver assistance, passenger comfort and vehicle safety. Apart from its general characteristic...

Vehicular Ad-hoc Networks (VANETs) have been gaining significant attention from the research community due to their increasing importance for building an intelligent transportation system. The characteristics of VANETs, such as high mobility, network partitioning, intermittent connectivity and obstacles in city environments, make routing a challenging task. Due to these characteristics of VANET...

--Vehicular Ad Hoc Networks (VANETs) have grown out of the need to support the growing number of wireless products that can now be used in vehicles. These products include remote keyless entry devices, personal digital assistants (PDAs), laptops and mobile telephones. As mobile wireless devices and networks become increasingly important, the demand for Vehicle-to-Vehicle (V2V) and Vehicle toRoa...

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...
