REDUCING INTERFERENCES IN VANETS?

By Admin on

VEHICULAR AD-HOC NETWORK

                                  Vehicular ad hoc networks (VANETs) are a subclass of MANETs that is expected to have a key role in the intelligent transportation systems of the future. VANETs provide vehicle-to-vehicle and vehicle-to-roadside communication in order to support safety and comfort applications. Despite being a subclass of MANETs, VANETs have fundamentally different behavior. This paper presents a scheme consisting of a media access control protocol and a clusteringalgorithm designed to reduce interferences in VANETs. Our scheme, which is intended for safety applications in highway environments, employs dynamic multihop clustering, allows better utilization of network resources, and improves network performance.


REDUCING INTERFERENCES IN VANETS

Vehicular ad hoc networks (VANETs) are a class of wireless networks that is expected to have a key role in the intelligent transportation systems of the future. Already in recent years, the U.S. Federal Communications Commission and the European Telecommunications Standards Institute have allocated spectrum for such systems, and an IEEE communications standard for them is under development. VANETs provide vehicle-to-vehicle and vehicle-to-roadside communication in order to support two main types of applications: safety applications such as road-hazard notification and sending emergency messages from an accident site, and comfort applications such as advertisements, parking space availability, traffic estimation, and traffic-jam notifications.
