摘　　要：未来无线网络将提供高速率多媒体宽带数据业务,为保证传输的可靠性和有效性,协作通信技术被引入到无线网络中。提出一种基于博弈论的无线宽带网络协作资源管理策略。该策略通过确定转发价格和协作资源量求解Nash均衡点,利用Pareto最优理论验证结果的有效性,并运用理论分析方法论证博弈论用于协作资源分配的可行性和合理性。仿真结果表明,与按照确定价格分配协作资源的策略相比,该策略可支持更好的网络性能。In the future wireless communication networks,high rate multimedia broadband data traffic needs to be provided.In order to ensure the reliability and validity,cooperation communication technology has been introduced in wireless networks.Thus,in this paper,a game theory based cooperative resource management strategy in wireless multimedia networks was proposed.Nash equilibrium point was found by confirming the transmit price and cooperation resource quantity,and results of the strategy were proved by Pareto optimal solution,and the rationality and feasibility of using game theory to allocate cooperative resources was verified by theoretical analysis.Simulation results show that,supported by the proposed strategy,the network performance is much better than that by using determinate price to allocate radio resources.
