Most licensed bands of the radio frequency spectrum today are underutilized. The research in cognitive radio (CR) technologies seeks to achieve intelligent dynamic spectrum access, hence higher throughput and more efficient spectrum utilization. It may also enable the co-existence of different wireless technologies, which can drive the development of diverse future applications. Vehicular ad hoc networks (VANETs) have many important applications in transportation, such as vehicle safety, automated tolling, enhanced navigation, traffic management, and in mobile information and entertainment (infotainment) services such as in-car Internet access, mobile office, collaborative expedition, and location-based services. This has stirred intense interest from both government and industry sectors. Both CR networks and VANETs are emerging wireless technologies. Each possesses unique characteristics and poses unique challenges. To realize the great potential, significant advances in virtually every protocol layer from the physical up to the application layers within the end-to-end communication paradigm are required.

当今无线电频谱的大多数许可频带未得到充分利用。认知无线电（CR）技术的研究目标是实现智能的动态频谱接入，从而获得更高的吞吐量和更有效的频谱利用率。它还可以实现不同无线技术的共存，从而推动未来各种应用的发展。车载自组织网络在交通运输领域有着重要的应用，如车辆安全、自动收费、增强导航、交通管理等，在移动的信息和娱乐服务领域也有着重要的应用，如车载互联网接入、移动的办公、协作探险和基于位置的服务等。 这引起了政府和工业部门的强烈兴趣。CR网络和VANESTO都是新兴的无线技术。每一个都有其独特的特点，并提出了独特的挑战。为了实现巨大的潜力，需要在端到端通信范例中从物理层到应用层的几乎每个协议层都取得重大进展。
