摘　　要：认知Ad Hoc网络是一种特殊的无线网络,与传统的无线Ad Hoc网络不同,它需要考虑主用户与认知用户的接入优先级问题,因此传统的路由技术不适用于认知Ad Hoc网络。简单介绍了认知Ad Hoc网络的架构,列举了传统Ad Hoc无线网络的路由算法并分析它们的缺点。为了适应认知Ad Hoc网络的特点,基于不同的参数指标,研究人员提出了一系列高效的算法,将重点分析这些路由算法。Cognitive Ad Hoc network, as a special kind of wireless network, is different from traditional Ad Hoc network, and for this network the access priority problem of primary and cognitive users must be con- sidered, thus the traditional routing algorithm is not applicable to the cognitive Ad Hoc network. This pa- per gives a brief introduction of its infrastructure, describes the routing algorithm of traditional Ad Hoc wireless network and analyzes its shortcomings. For adaptability to the characteristics of Ad Hoc wireless network, a series of efficient algorithms based on various parameters are proposed, with emphasis on the a- nalysis and description of these routing algorithms.
