| 摘 要： | 尽管QoS保障对WiMAX 网状网络 (WiMAX Mesh Network, WMN)的实际应用非常重要，但IEEE 802.16尚未明确定义WMN的QoS实现机制,现有研究主要集中在路由算法和逐跳的QoS保证方面.本文在分析WMN QoS保障机制的基础上提出了一种有效、动态的WMN QoS保障算法.该算法把WMN 视为一个整体, 描述了各节点在进行数据包处理时应该遵循的约束条件，并给出了各节点对网络流量的处理方式.本算法既提高了WMN的网络吞吐量,也确保了各节点对带宽使用的比例公平性. 本文开发了WMN 仿真平台，并通过仿真证明了本文所提出算法的效率与灵活性.

| Abstract: | Abstract: Though it is important for the deployment of WiMAX Mesh Network , the IEEE 802.16 Specification has not defined how to guarantee QoS in WMN. Most of current research only focuses on routing algorithm or Hop-by-Hop QoS guaranteeing. In this paper , we analyzed the WMN QoS guaranteeing mechanism, and we advanced a QoS - Guaranteeing algorithm for WMN, which described the traffic handling method of each node in a view of integrity. It used a Linear Programming Method to calculate the optimized traffic-handling pattern for each node ,and it gave some constraints for the WiMAX Mesh nodes. Our algorithm can improve the network throughput, and ensure fairness. To verify our algorithm , we developed a WiMAX Mesh simulating platform and ran our simulation on it. The simulation result showed that our algorithm is effective and feasible. |
