Robust Communication in Vehicular Ad Hoc Networks

The primary goal of VANET is to provide road safety measures where information about vehicle’s current speed, location coordinates passed with or without the development of infrastructure. This paper proposes an enhancement scheme of Pseudonym management with better privacy scheme. The pseudonym design focus on privacy among network participants. The major limitation of these vehicular ad hoc n...

With growing interest in using cognitive radio (CR) technology in wireless communication systems for vehicles, it is envisioned that future vehicles will be CR-enabled. This paper discusses CR technologies for vehicular networks aimed at improving vehicular communication efficiency. CR for vehicular networks has the potential of becoming a killer CR application in the future due to a huge consu...

Data dissemination or diffusion service is the process of distributing a certain amount of information to the users such as vehicle drivers or mobile users especially in wireless networks. It also plays a significant role in numerous applications of Vehicular Ad hoc Networks (VANETs). Data Dissemination problem has been addressed by many researchers so far in many contexts. This paper presents ...

The performance of VANET remains optimum within thousand meters and after that due to high packet loss rate communication among vehicles is not feasible. Finding optimal path is a typical task for dynamic protocols. The research objective is to study some of the important QOS metrics in VANET & vehicular traffic management solutions to improve overall safety of traffic. Keywords— Vehicular Ad h...

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)...

The successful introduction of vehicular communication has to posses the design of robust security architecture that should be able to cope with security threats. Ad hoc networks are a new wireless networking paradigm for mobile hosts. Vehicular networks are likely to become the most relevant form of mobile ad hoc networks. . In this paper, we have discussed the various suggested security archi...

Vehicular ad hoc network is the emerging technology for current research trend. And In Vehicular ad hoc network The Broadcast is a frequently used method in Inter-Vehicle Communication (IVC) Systems. Possible applications relying on broadcast include sharing emergency, traffic, weather, and road data among vehicles, and delivering advertisements and announcements. It provides important control ...

The successful dissemination of emergency messages in vehicular ad hoc networks can make a difference between life and death. To achieve the life-saving goals, emergency message dissemination needs timely and lossless medium access in vehicular ad hoc networks. Although in the literature there are existing medium access control (MAC) protocols that support priority medium access, these protocol...

Inter Vehicle Communication (IVC) has become a major topic during the last few years. Within the FleetNet project a novel mobile ad hoc network will be developed – based on the UMTS Terrestrial Radio Access Time Division Duplex (UTRA TDD) air-interface – to interconnect vehicles and roadside gateways via a mobile Internet. In this paper we focus on the impacts of vehicular traffic dynamics on p...
