Vehicular ad hoc networks (VANETs) are getting a lot of consideration these days due to the various applications and possible benefits they offer for their future users. Safety information exchange allows important applications, such as the alerting drivers during crossroads traversing and track merging, and thus, plays an important role in VANET applications. In a VANET, vehicles will depend o...

VANET (Vehicular Ad Hoc Network) is actually an important field for the development of a variety of services. In VANET charging and billing of services could not be enabled in the same way as in classical mobile and fix networks and MANET (Mobile Ad Hoc Network) because of the characteristics of such network namely the high speed of nodes, frequent disconnection between nodes, rapidly changing ...

In comparison to other communication networks, Vehicular Ad-hoc Networks (VANETs) have unique requirements with respect to applications, types of communication, self-organization and other issues. In order to meet these requirements, the structuring of functionalities into protocols and their interaction must be re-thought. The traditional approach of decomposition of functionality into protoco...

Several approaches can be identified in the domain of vehicular ad hoc networks (VANET). Internet Protocol version 6 (IPv6) networking and non-IP geographical networking can each fulfill a subset of the application requirements. In general, a combination of both techniques is proposed to meet all of the application requirements. In this case, packets of one VANET routing protocol are encapsulat...

Vehicular Ad Hoc Network (VANET) allows vehicles to exchange information about road and traffic conditions through wireless communications. Nevertheless, providing reliable and authenticated information without violating the user's privacy seems contradictory. In this paper, we propose an Anonymous Announcement System especially designed for Electric Vehicle (EV) in VANETs to achieve the aforem...

This paper initiates the study of scaling laws for vehicular ad hoc networks (VANET)s. It provides a general framework to study VANETs. The fundamental capacity limits of these networks are investigated and we show how the road geometry affects this capacity. The VANET capacity is calculated for different road structures. The need for new capacity metrics is discussed. These results are obtaine...

A Vehicular Ad hoc NETwork (VANET) is a type of mobile Peer-To-Peer wireless network that allows providing communication among nearby vehicles and between vehicles and nearby fixed roadside equipment. The lack of centralized infrastructure, high node mobility and increasing number of vehicles in VANETs result in several problems discussed in this paper, such as interrupting connections, difficu...

Vehicular adhoc networks (VANETs) are the important subset of mobile ad-hoc network (MANET) application which uses set of smart vehicles on road in the form of mobile nodes. The VANET provides the benefits of road safety and travellers comfort while protecting driver’s privacy from different types of attacks perpetrated by adversaries. In the forthcoming, it is usual that have vehicles which gr...

The need to have Intelligent Vehicle System has paved the way for the rapid emergence of Vehicular Adhoc Networks (VANET) which allows communication to take place between the vehicles. The effective implementation of VANET, a sub class of mobile adhoc networks, depends upon the routing protocols used which behave differently under different environments. This paper attempts to study the behavio...

A Vehicular Ad hoc Network (VANET) is a type of wireless ad hoc network that facilitates ubiquitous connectivity between vehicles in the absence of fixed infrastructure. Beaconing approaches is an important research challenge in high mobility vehicular networks with enabling safety applications. In this article, we perform a survey and a comparative study of state-of-the-art adaptive beaconing ...
