摘要
描述一种SON结构,基于博弈论方法研究网络带宽分配问题,建立双层规划模型,模型中考虑各种因素例如服务QoS、带宽成本以及流量需求。上层规划是以SON利益最大化为目标而建立的,下层规划是SON在弹性需求下的Wardrop用户均衡模型。用下降方向法和差分灵敏度分析法结合的启发式方法求解模型。
After giving a SON architecture,studies the network bandwidth allocation problem based on thegame theory method and establishes the bi-level programming model and considers in the modelof the various factors such as service QoS,bandwidth costs and flow demand.The goal of establishing the upper level model is benefit maximization for SON,while the lower level model is aWardrop user equilibrium model with elastic demand.Finally,designs a heuristic solution algorithm based on drop direction method and difference sensitivity analysis method for the bi-levelprogramming model.
