| 摘 要： | 认知无线电网络中的节点具有动态频谱接入的特点,进而产生可用频谱的不规则性,这与传统无线多跳网络有很大不同,从而导致了认知无线电网络路由面临新的挑战.在介绍认知无线电网络路由的特点之后,对路由协议进行了初步分类.然后着重分析了目前认知无线电网络较为重要的路由协议的主要机制,详细比较了路由协议的主要类别和特点,最后总结了好的认知无线电网络路由协议的特点,并对未来发展趋势进行了初步展望.

| Abstract: | Nodes in cognitive radio networks are characterized by dynamic spectrum access,which results in spectrum heterogeneity.Routing in cognitive radio networks is confronted with new challenges,given that the differences between cognitive radio networks and traditional multi-hop wireless networks.After describing the characteristics of routing in cognitive radio networks,the classification standards for routing protocols are presented.Then the key mechanisms of the existing representative routing protocols are a... |
