认知无线电网络被设计为机会主义地利用授权频带。为了部署认知无线电网络，节点需要执行邻居发现过程，以便实现网络中的通信和连接。邻居发现不仅有助于在认知无线电网络中的成功和有效的通信，但也提供了解决方案，大多数其他传统的无线网络的问题，如八卦或广播的消息，全球公共控制信道分配等。在本文中，我们提供了一个调查传统的无线网络和认知无线电网络的邻居发现。在这个角度来看，我们首先提供的邻居发现的基础知识和功能，以及从传统的无线网络向认知无线电网络移动时所面临的挑战，为了更好地理解认知无线电网络中的邻居发现铺平了道路。我们提供了详细的分类在传统的无线网络和认知无线电网络中的邻居发现协议。最后，公开的问题，挑战和未来的研究方向已经突出了在认知无线电网络中的邻居发现。
Cognitive radio network is designed to opportunistically exploit the licensed band. To deploy a cognitive radio network, nodes need to perform the neighbor discovery process in order to enable communication and connectivity in the network. Neighbor discovery not only helps in successful and efficient communication in cognitive radio networks but also provides solutions to a majority of other traditional wireless network problems, such as gossiping or broadcasting a message, a global common control channel allocation, etc. In this paper, we provide a survey on neighbor discovery for traditional wireless networks and cognitive radio networks. In this perspective, we first provide basics and features of neighbor discovery, as well as, the challenges when moving from traditional wireless networks towards cognitive radio networks, in order to pave the way for a better understanding of the neighbor discovery in cognitive radio networks. We provide detailed taxonomy of neighbor discovery protocols in traditional wireless networks and cognitive radio networks. Finally, open issues, challenges, and future research directions have been highlighted for neighbor discovery in cognitive radio networks.
