【摘要】：认知无线网络通过对无线环境的感知获得频谱空洞信息,并以动态频谱接入为关键技术,机会地使用空闲频谱,与传统的无线网络相比,具有更高的网络通信资源利用率。认知能力作为认知无线网络的本质属性,其安全保障直接关系到认知无线网络的实用化进程。由于网络结构的复杂性、节点的移动性等问题,认知能力在各个认知环节中均面临不同程度的安全威胁。首先从认知循环:认知通信、资源感知、推理决策和服务适配4个环节分析认知能力保障所面临的安全问题以及相应的解决方案,然后总结现有方法的不足和缺陷,提出认知能力保障策略基于信任机制的发展趋势;最后指出未来认知能力保障领域所面临的挑战,并对该领域的研究方向进行了展望。
[Abstract]:Cognitive wireless network obtains spectrum empty information through perception of wireless environment, and takes dynamic spectrum access as the key technology, and uses idle spectrum opportunely. Compared with traditional wireless network, cognitive wireless network has higher utilization of network communication resources. As the essential attribute of cognitive wireless network, cognitive ability is directly related to the practical process of cognitive wireless network. Due to the complexity of network structure and the mobility of nodes, cognitive ability is facing various security threats in various cognitive links. Firstly, the paper analyzes the security problems and corresponding solutions of cognitive ability guarantee from four aspects: cognitive communication, resource perception, reasoning decision and service adaptation, and then summarizes the shortcomings and defects of existing methods. Finally, the paper points out the challenges faced by the field of cognitive ability guarantee in the future, and looks forward to the research direction in this field.
