摘　　要：为了提高车载自组网的性能和频谱利用率,多接口动态频谱分配技术成为车载自组网的研究热点。介绍了车载自组网动态频谱分配算法的关键设计基础,对多接口多信道网络技术的发展现状进行了分类阐述,对车载自组网动态频谱分配技术的研究进行了展望。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.
