A Vehicular Ad-Hoc Network (VANET) is categorized as a Mobile Ad-Hoc Network (MANET) which delivers wireless network servies with an aim to improve road safety and enhance driving comfort. Diverse applications of Vehicular Ad-Hoc Networks such as infotainment, road safety and public safety have made VANETs as a notable and emerging area of research and development. As of now, numerous vehicular...

Vehicular ad hoc networks (VANETs) have attracted a lot of attention over the last few years. VANETs are being used to improve road safety .Many forms of attacks against VANETs have emerged recently that attempt to compromise the security of such networks. Such security attacks on VANETs may lead to catastrophic results such as the loss of lives or loss of revenue for those valueadded services....

Vehicle handover from one road-side unit to another is a common phenomenon in vehicular ad-hoc networks (VANETs). Authenticating vehicles effectively is the key to success of VANETs. Recently, Li and Liu proposed a lightweight identity authentication protocol for VANETs, which was claimed to integrate efficiency and security. However, in this paper, we show that their protocol is vulnerable to ...

Mobile Ad Hoc Network and Vehicular AdHoc Networks are emerging area for research and development. VANETs are subclass of MANETs. But unlike MANETs it does not have battery constraints and have high mobility. Unicast and Multicast protocols in MANETs and VANETs use broadcasting to provide important control and route establishment. Possible applications of VANETs relying on broadcast for sharing...

In Vehicular Ad hoc Networks (VANETs) the mobility of the nodes is the main concern. This mobility of nodes makes the route unstable and unreliable for the information exchange and communication between two nodes in the network. To enhance the performance and throughput of the VANETs, routes between nodes must be reliable and stable. In this paper, we study the significance of path duration and...

Vehicular ad hoc networks (VANETs) is a promising emerging technology that enables a wide range of appealing applications in road safety, traffic management, and passengers and driver comfort. The deployment of VANETs to enable vehicular Internet-based services and mobile data offloading is also envisioned to be a promising solution for the great demand of mobile Internet access. However, devel...

-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 veh...

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...
