Broadcast is an important operation in ad hoc networks, especially in distributed multi-hop multichannel networks. Although the broadcasting issue has been extensively investigated in traditional single channel and multi-channel ad hoc networks, there are unique challenges that are un-explored in the broadcast design in cognitive radio ad hoc networks. Existing schemes can have serious performance degradation due to the neglect of the dynamics in the spectrum availability in cognitive radio networks. The research objective of this project is to design, analyze, and evaluate new broadcast protocols for multi-hop cognitive radio ad hoc networks without a common control channel. The broadcast design is aimed at maximizing the broadcast success rate and minimizing the average broadcast delay simultaneously. The approach is focused on exploiting the spectrum correlations of neighboring nodes and the spectrum diversity of different nodes in designing new channel rendezvous, scheduling, and collision avoidance algorithms to achieve the broadcast performance goals in practical scenarios. This project will provide fundamental and complementary solutions to existing cognitive radio networking research on other network operations. It will also help generate innovative techniques to numerous applications of the cognitive radio and dynamic spectrum access technology. 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.

广播是自组织网络中的一项重要操作，尤其是在分布式多跳多通道网络中。尽管广播问题在传统的单通道和多通道自组织网络中已得到广泛研究，但认知无线电自组织网络的广播设计中存在尚未探索的独特挑战。由于忽略了认知无线电网络中频谱可用性的动态性，现有方案可能会出现严重的性能下降。该项目的研究目标是设计、分析和评估没有公共控制信道的多跳认知无线电自组织网络的新广播协议。广播设计的目的是同时最大化广播成功率和最小化平均广播延迟。该方法的重点是利用相邻节点的频谱相关性和不同节点的频谱多样性来设计新的信道交会、调度和冲突避免算法，以实现实际场景中的广播性能目标。该项目将为其他网络运营的现有认知无线电网络研究提供基础和补充解决方案。它还将有助于为认知无线电和动态频谱接入技术的众多应用产生创新技术。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。
