SCALABILITY PROBLEM AND ITS SOLUTION IN VEHICULAR AD-HOC NETWORKS

Abstract

The field of inter-vehicular communications (IVC, also known as vehicle-to-vehicle communications, V2V, or vehicular ad hoc networks, VANETs) has been gaining momentum in recent years. Numerous emerging communications applications are unique to the vehicular setting. These applications include safety applications that will make driving safer, mobile commerce, and roadside information services that can intelligently inform drivers about congestion, businesses, and services in the vicinity of the vehicle, as well as other types of locally relevant news. These emerging services are not well supported by the limited communication options available on cars today. Appropriately, the growing importance of IVC has been recognized by governments, corporations, and the academic community. IVC is recognized as an important component of intelligent transport systems (ITS) in various national ITS plans. As such, governments have allocated spectrum for IVC and similar applications (e.g., various con...
