文章首先简要介绍了非合作博弈理论的基本定义和性质,综述了运用非合作博弈理论来解决无线通信网络中资源管理等诸多问题的研究现状。在此基础上,探讨了在非合作博弈框架下,引入相关均衡的理论意义和实现途径。继而,文章以如何解决面向绿色无线通信网络的协同策略选择问题为例,从能量有效性角度提出了基于相关均衡的协同策略选择机制。面对分布式且颇具竞争性的绿色无线协同网络,相关均衡能在所建立的非合作博弈的框架下允许潜在中继节点之间某种形式的合作的模型化,从而激励潜在中继节点得到接近“合作的”博弈结果。理论分析和仿真结果验证了所提机制能在收敛性、Pareto最优性和max-min公平性等方面收效甚好。
The article first briefly introduces the basic definition and properties of noncooperative game theory, and reviews the research status quo of using noncooperative game theory to solve many problems such as resource management in wireless communication networks. On the basis of this, the paper discusses the theoretical significance and the way to bring about the equilibrium under the framework of non-cooperative game. Then, this paper takes the example of how to solve the problem of cooperative strategy selection for green wireless communication networks, and proposes a coordination strategy selection mechanism based on correlation equalization from the perspective of energy efficiency. In the face of distributed and competitive green wireless collaborative networks, the relevant equalization can model some form of cooperation between potential relay nodes in the framework of the established non-cooperative game so as to motivate potential relay nodes to obtain Close to “cooperative” game results. The theoretical analysis and simulation results show that the proposed mechanism can work well in convergence, Pareto optimality and max-min fairness.
