中文摘要：

针对多跳无线局域网（MWLAN）的带宽受限以及网络拓扑动态性等特点，本文提出了一种优化的多跳无线局域网QoS路由（MQR）协议，该协议提出的节点生成树算法可以根据移动节点和AP之间的跳数以及节点剩余能量组织MWLAN的树形网络拓扑；同时，该协议改进了传统的节点剩余带宽估计算法，使得网络节点可用带宽估计更加精确，在寻路过程中根据节点可用带宽信息为数据流提供软状态QoS保证．仿真结果表明，MQR协议可以有效的降低平均寻路确认时延并提高网络带宽利用率，同时，寻路开销和平均端对端分组时延也得到较好的控制．

英文摘要：

Due to the bandwidth constraint and dynamic topology of MWLAN. In this paper we present a complete solution for QoS routing for Multihop wireless LAN. In this protocol, nodes-tree algorithm can organize the tree network topology based on the hop counts between MN and AP and the residual energy of the MNs, what＇s more, this protocol improve the traditional residual bandwidth estimation algorithm to make the node available bandwidth estimation much more precise and provide soft- QoS guarantee for packet flow based on the node available bandwidth during the routing. Simulation result shows that, MQR can degrade the routing acknowledgement time and improve bandwidth utilization rate. What＇s more, routing spending and end to end delay can be improved in most cases.
