异构无线系统中基于博弈的动态频谱管理

A Game-based Dynamic Spectrum Management for Heterogeneous Wireless System

为提高频谱使用率并增加异构无线网络收益,用微观经济学的无限期轮流出价讨价还价博弈模型进行了异构网络间动态频谱管理的研究,提出了基于讨价还价理论的动态频谱管理(BDSM)方案。根据相关博弈理论,引入讨价还价耐心因子后BDSM存在唯一的均衡点。基于此,提出了实现BDSM方案的简化流程。仿真结果显示,BDSM能有效地提高频谱使用率、扩大单个运营商的利润并提高用户满意度。

Based on infinite alternating-offer bargaining games in microeconomics, a bargaining-based dynamic spectrum management （BDSM） scheme is proposed for future heterogeneous wireless system. In accordance with the game theory, there exists a unique equilibrium in BDSM by introducing bargaining patience factor. Therefore, the BDSM implementation procedures are simplified. Simulation results show that with imperfect load predicting, BDSM is effective in improving the utilization of spectrum, expanding the individual operator＇s profits and enhancing the users＇ satisfaction ratio among different radio access networks （RANs）.
