对策论方法在信息网络资源分配中的应用

在研究复杂信息网络的资源分配问题时，网络资源提供者和用户之间对资源的使用存在不同的优化目标，导致对资源分配策略存在多种评价准则。为便于网络管理者进行分布式的资源管理和计费，采用对策论模型分析用户对资源的竞争和处理网络传输拥塞正日益受到广泛的重视。本文首先指出资源分配和计费管理的几个主要难点，比较了中心化与非中心化控制策略的差别，而后综述了采用对策论模型进行资源分配和管理的优点，重点讨论了在非中心化条件下对策均衡解与资源利用效率以及网络计费管理策略之间的关系，最后对基于对策论模型的信息网络流量控制与管理策略进行总体评述。

Using Game Theoretic Approaches for Resource Allocation in Information Network

When dealing with resource allocation problem in the complex information network,service providers and users of the network have different optimizing strategies in resource utilization,thus leading to the different evaluation criterion of resource management and charging issues.In order to price and manage the resources in a distributed manner,the game theoretic approaches to analyze competitive resources among the users and to manage the network congestion during transmission have drawn a wide attention among the researchers.In this paper,we first point out some key problems in resource allocation and the differences between the centralized and decentralized allocation strategy,then we give the advantages of game theoretic approaches in resource allocation.The relationship between game theoretic equilibrium and efficiency of resource utilization as well as pricing and managing network resources through decentralization is thoroughly discussed.Finally,we give some conclusive comments on the flow control and resource management of information network using game theoretic model.
