市场竞争下的三阶段动态博弈频谱接入算法
A Three Stage Market Competition-based Dynamic Game of Spectrum Access Algorithm
摘要
Abstract
A three stage market competition-based dynamic game of spectrum access algorithm is proposed by using a two-layer dynamic spectrum access network model. Backward induction and Bertrand game theory are adopted to solve the spectrum access problem. Two duopoly mobile virtual operators (MVNO) determine the amounts of the spectrum in succession and attracts the secondary end users by the price. The end users make their spectrum access options based on the heterogeneous preference over the rates and prices. The accuracy and stability of the algorithm has been analyzed theoretically and certificated by the existence of the unique Nash equilibrium. The simulation results show that the MVNOs could make investment optimally, pricing decisions flexibly, and maximize their profits. Such algorithm also provides a reference model for the practical application.关键词
