摘要:

协作频谱感知能够有效优化分布式认知无线电网络中的频谱感知结果。然而,协作频谱感知也带来了一些安全威胁,尤其是恶意协作次用户的攻击。针对上述问题,文章提出了一种基于综合信誉机制和元图理论的可信频谱感知协作次用户选取策略,该策略将次用户的信誉评估结果与元图理论结合,将信誉值作为元图中计算次用户间关系的主要参数,建立不同次用户之间的可信关系,以选取可信的协作次用户。仿真实验和结果分析表明,文章所提出的策略能够有效提高被选取的协作次用户的可信度,从而提高抵抗频谱感知数据篡改攻击的能力和信道的检测率。

Abstract:

Collaborative spectrum sensing can effectively optimize the spectrum sensing results in the distributed cognitive radio networks (DCRN). However, the collaborative spectrum sensing also brings some security threats, especially the threats from the malicious collaborative second users’ attacks. To resolve the above problems, this paper proposes a trustworthy spectrum sensing collaborative second user selection strategy (RMCSS) based on integrated reputation mechanism and metagragh. The strategy combines the reputation evaluation results of second users with the metagraph theory, takes the reputation values as the main parameters to calculate the relationship between second users in the metagraph, establishes the trust relationship between different second users, and selects the trusted second users.Simulation experiments and results analysis show that the proposed strategy can effectively improve the credibility of the selected second users, thereby improving the ability to resist spectrum sensing data tampering attacks and channel detection rate.
