A fundamental operation for users in cognitive radio networks (CRNs) to access the spectrum is channel rendezvous. After rendezvous is established, channel information exchange and propagation among users are also essential for efficient spectrum access. Existing studies on channel rendezvous in CRNs have limitations and are unsuitable for efficient access scenarios. Additional information about users can help generate intelligent designs in CRNs that can shorten spectrum access delay. However, due to practical constraints, such information is extremely difficult to obtain before rendezvous is established. Mining the social patterns of CR users (or secondary users, SUs) and intelligently utilizing the captured social information is a promising approach. The objective of this project is to design, analyze, and evaluate fast and efficient spectrum access schemes for CRNs without a common control channel. One unique feature of this work is the consideration of SU social patterns and the incorporation of social analysis to enhance spectrum access efficiency. The approach involves analyzing the time, location, and spectrum-dependent social patterns of SUs; identifying and addressing new challenges in channel rendezvous, security, and recommendation designs with the assistance of SU social analysis; and proactively utilizing social patterns of SUs for fully distributed fast and secure spectrum access design. This project will have a significant impact on efficient spectrum access. Social analysis of users is a critical component to further enhance spectrum access efficiency and accelerate CRN deployment. This interdisciplinary research is potentially transformative as it will help generate innovative techniques to numerous CRN applications. It will also greatly enhance the understanding of social interactions of mobile users in wireless networks. This project provides an excellent opportunity for graduate and undergraduate research students to gain valuable educational training and research experiences. The research results will be presented at IEEE/ACM journals and international conferences.

认知无线电网络（CRN）中用户访问频谱的基本操作是信道交会。交会建立后，用户之间的信道信息交换和传播对于高效的频谱接入也至关重要。现有的 CRN 信道交会研究存在局限性，不适合高效接入场景。有关用户的附加信息有助于在 CRN 中生成智能设计，从而缩短频谱访问延迟。然而，由于实际限制，在建立交会点之前获得此类信息极其困难。挖掘 CR 用户（或二级用户，SU）的社交模式并智能地利用捕获的社交信息是一种有前途的方法。该项目的目标是设计、分析和评估无需公共控制信道的 CRN 快速高效的频谱接入方案。这项工作的一个独特之处是考虑了 SU 社会模式并结合社会分析来提高频谱接入效率。该方法包括分析 SU 的时间、位置和频谱相关的社交模式；在 SU 社会分析的帮助下识别和解决通道交汇、安全和推荐设计方面的新挑战；主动利用 SU 的社交模式进行完全分布式、快速、安全的频谱接入设计。该项目将对高效频谱接入产生重大影响。用户社交分析是进一步提高频谱接入效率、加速CRN部署的关键组成部分。这项跨学科研究具有潜在的变革性，因为它将有助于为众多 CRN 应用产生创新技术。它还将极大地增强对无线网络中移动用户社交互动的理解。该项目为研究生和本科生提供了获得宝贵的教育培训和研究经验的绝佳机会。研究成果将在IEEE/ACM期刊和国际会议上发表。
