摘要:
为了解决无线Mesh网络(WMN)无法自发在Mesh网关处确保上下行带宽公平分配的问题,提出了基于时间窗口的无线Mesh网络的上下行带宽公平性定义。这些定义是在运用NS2进行仿真实验的基础上,充分考虑了无线Mesh网络的上下行方向动态变化的TCP流数负载和各条流不同的需求带宽等OoS指标的基础上提出来的,描述了无线Mesh网络作为Intemet接入网络提供公平服务时应满足的基本条件,为后续研究高效的优化公平效率模型和实现上下行公平性的机制或算法打下了坚实的基础
Abstract:
In order m solve the problem which wireless mesh network(WMN) can not spontaneously insure fair distribution of bandwidth between uplink and downlink at the gateway ,it proposes some definitions of uplink/downlink fairness based on time window for WMN. By simulating with NS2 first, these definitions take uplinl/downiink TCP flow load and QoS index like requested bandwidth into account, and well describe the Intemet access characteristic of WMN and the basic condition which should be satisfied when WMN is uplink/downiink fairly. The proposed definitions supply a good foundation for the subsequent research of optimization model between fairhess and efficiency, and related mechanism or algorithm to realize them
