基于云模型的军事航空通信频谱共享信任机制研究

Military Aeronautical Communication Spectrum Sharing Trust Mechanism Based on Cloud Model

针对军事航空通信频谱共享的特殊性,提出一种基于云模型的频谱共享信任机制。通过对信任的相关理论进行研究,引入云模型理论,构建了基于云模型的频谱共享信任体系结构,确立了频谱共享信任体系中的信任交互关系。运用云模型进行信任评价,实现了将频谱共享中模糊定性的信任属性向精确定量的信任等级的转换,较好地解决了频谱共享信任关系建立等系列问题。设计了信任评价实验,验证了信任评价模型的有效性和实用性,为基于信任机制的频谱共享策略实施提供了有效的支撑。

In response to the particularity of military aeronautical communication spectum sharing, a spectrum sharing trust mechanism based on cloud model was proposed. By the use of trust relevant theories and the introduction of the cloud model theory, a system framework of spectrum sharing based on the cloud model theory was constructed, and the mutual relationship of spectrum sharing system was confirmed. The clear idea and concrete method of trust evaluation based on the cloud model was proposed at last. The trust evaluation approach can implement the conversion from the fuzzy qualitative trust attributes to the precise quantification trust levels,which could resolve the series problems effec- tively during the establishment of spectrum sharing trust relationships. The trust evaluation experimentation was de- signed. The result show that the trust evaluation model is of validity and practicability, which provide the effective sup- port of spectrum sharing strategy based on the trust mechanism.
