have edited this new book to reflect the present and future challenges in wireless technologies for vehicular ad hoc networks. New technologies are being developed for vehicular ad hoc networks, and these networks provide an efficient method for today's complex vehicle communications. Emerging vehicular ad hoc networks in the forms of Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I)...

Mobile ad-hoc networks (MANETs) have a decentralized nature that makes them suitable for variety of applications [...]

Sybil attack is a security threat wherein an attacker creates and uses multiple counterfeit identities risking trust and functionality of a peer-to-peer system. Sybil attack in vehicular ad hoc networks is an emergent threat to the services and security of the system. In the highly dynamic environment of vehicular ad hoc networks, due to mobility and density of nodes, it is challenging to detec...

Vehicular Ad Hoc Networks (VANETs) have become an emerging area of wireless ad hoc networks in the last years. They facilitate ubiquitous connectivity between vehicles through Vehicle-to-Vehicle (V2V) or Vehicle-to-Roadside (V2R) and Roadside-to-Vehicle (R2V) communications. VANETs aim to improve the safety of passengers and traffic flow, reduce pollution to the environment and enable in-vehicl...

In a Vehicular Ad-hoc Network (VANET), the amount of interference from neighboring nodes to a communication link is governed by the vehicle density dynamics in vicinity and transmission probabilities of terminals. It is obvious that vehicles are distributed non-homogeneously along a road segment due to traffic controls and speed limits at different portions of the road. The common assumption of...

The rapid increase of vehicular traffic and congestion on the highways began hampering the safe and efficient movement of traffic. Consequently, year by year, we see the ascending rate of car accidents and casualties in most of the countries. Therefore, exploiting the new technologies, e.g. wireless sensor networks, is required as a solution of reduction of these saddening and reprehensible sta...

The Vehicular Ad-Hoc Network, or VANET, is an expertise that usages moving cars as nodes in a network to generate a moveable network. VANET turns each contributing car into a wireless router or node, permitting cars roughly 100 to 300 meters of each other to associate and, consecutively, form a network with an extensive range. Since vehicular ad hoc networks require the transmission of the safe...

A vehicular ad-hoc network (VANET) is an autonomous and self-configuring network of mobile hosts connected by wireless links. It is a highly dynamic network and has harsh channel conditions. Cluster-based MAC scheme in VANET is needed to overcome the lack of specialized hardware for infrastructure and the mobility to support network stability and channel utilization. This work presents a MAC al...

VANET (Vehicular Ad hoc Network) is an emerging research area, focused on providing vehicle to vehicle and vehicle to infrastructure communication. It is becoming a reality, by the investments of car manufacturers and Public Transport Authorities. Soon many essential vehicle network components will be in place, paving the way to multitude opportunities for other vehicular network applications. ...

Vehicular communication is considered to be a backbone for many critical safety applications. In order to achieve a better implementation of any vehicular communication scenario, an efficient, accurate and reliable simulator is essential. Various open source and commercial simulating tools are available for this purpose. One of the key issues in this regard is the selection of a reliable simula...
