超短波电台频谱动态博弈接入算法

Dynamic Game Access of VHF Radio Spectrum

在超短波电台通信中,用户移动性强、网络拓扑结构多变、网络环境复杂,目前的频谱分配方法无法满足其快速、准确地频谱接入的需要。博弈论作为一种重要的数学理论,在动态频谱接入中得到了越来越广泛的应用。以此为出发点,将博弈论与超短波电台频谱接入技术相结合,提出了时变信道的分布式信道选择算法和周期重启的分布式信道选择算法,使分布式超短波电台用户能够通过相互博弈达到稳定的接入状态,并通过MATLAB仿真验证算法的有效性和优越性。

In ultra-short wave radio communication, user mobility is strong, network topology structure is changeable, and network environment is complex. Current spectrum allocation methods cannot meet the needs of fast and accurate spectrum access. As an important mathematical theory, game theory is more and more widely used in dynamic spectrum access. Based on this, this paper combines game theory with ultra-short wave radio spectrum access technology to propose the distributed channel selection algorithm for time-varying channels and distributed channel selection algorithm with periodic restart. The algorithm enables distributed ultra-short wave radio users to achieve a stable access through mutual games and the effectiveness and superiority could be verified by MATLAB simulation.
