【摘要】 针对传统的拥塞控制缺乏合理的激励机制,或者没有考虑用户的不同服务质量需求,在多用户的网络模型中,通过引入基于效用函数的激励Stackelberg策略,网络方(主方)利用价格手段对用户方(从方)进行网络资源的控制,使双方都达到了最优——既保证了网络方的最大收益,也保证了用户方的最佳资源利用率,从而达到拥塞控制的目的.仿真试验表明,该方法可以限制用户的资源利用率,并达到约束条件下的期望值.更多还原

【Abstract】 The traditional approaches to congestion control lack proper incentive mechanism,and ignore QoS of different users.By introducing incentive Stackelberg strategy based on the utility function into the model of multi-user networks,the network provider(leader) can control the network users(follower) via pricing.So both sides reach to optimum,which means that not only the network provider gains optimal income but the users get hold of optimal network resources.Eventually,the aim of congestion control is achieved.Simulation results show that the method can restrict the usage of network resource by users and make the application rate arrive at expectated value under the restriction.更多还原
