Abstract

Abstract: A fundamental obstacle to deploy large scale VANET is the insufficient network throughput and large data packet delay when route hops and network scale increase due to the limited spectrum. Channel assignment has been an active research area due to the development of VANET. This paper presents an in-depth survey of some channel assignment approaches. The key design issues for multi-channel VANET are identified, laying down the fundamentation for discussion. A classification about channel assignment is presented. The future research directions and key technology are discussed at length.

Key words: vehicular ad hoc networks, multi-interface multi-channel, spectrum allocation
