无线网络中能量有效的资源分配：博弈论方法综述
Energy-Efficient Resource Allocation in Wireless Networks: An Overview of Game-Theoretic Approaches
摘要：
概述了无线网络中的能量有效的资源分配的博弈论方法。以多址接入网络为研究对象，证明了博弈论可以作为研究具有服务质量（QoS）约束的无线网络中资源分配的有效工具。一个家庭的非合作（分布式）游戏中，每个用户寻求选择一个策略，最大限度地提高自己的效用，同时满足其QoS要求。这里考虑的效用函数测量每焦耳能量消耗传输的可靠比特数，因此特别适合于能量受限的网络。每个用户在尝试最大化其自身效用时可用的动作至少是选择发射功率，并且根据情况，用户还可以能够选择其传输速率、调制、分组大小、多用户接收器、多天线处理算法或载波分配策略。给出了每个博弈的最佳对策和纳什均衡。利用这个博弈论框架，功率控制，速率控制，调制，时间和空间信号处理，载波分配策略和延迟QoS约束的能量效率和网络容量的影响进行了量化。
英文摘要：
An overview of game-theoretic approaches to energy-efficient resource allocation in wireless networks is presented. Focusing on multiple-access networks, it is demonstrated that game theory can be used as an effective tool to study resource allocation in wireless networks with quality-of-service (QoS) constraints. A family of non-cooperative (distributed) games is presented in which each user seeks to choose a strategy that maximizes its own utility while satisfying its QoS requirements. The utility function considered here measures the number of reliable bits that are transmitted per joule of energy consumed and, hence, is particulary suitable for energy-constrained networks. The actions available to each user in trying to maximize its own utility are at least the choice of the transmit power and, depending on the situation, the user may also be able to choose its transmission rate, modulation, packet size, multiuser receiver, multi-antenna processing algorithm, or carrier allocation strategy. The best-response strategy and Nash equilibrium for each game is presented. Using this game-theoretic framework, the effects of power control, rate control, modulation, temporal and spatial signal processing, carrier allocation strategy and delay QoS constraints on energy efficiency and network capacity are quantified.
