摘要:

提出了多速率无线Mesh网络中节点吞吐量分析模型,在公平性保证条件下用以分析基于IEEE 802.11协议构建的无线Mesh网络节点吞吐量.该模型计算出不同速率无线链路发送数据包的时间,寻找网络中单位时间内完成数据包发送时间最大的瓶颈冲突域,根据瓶颈冲突域内负载流量速率得到节点吞吐量最大值.仿真结果表明,该方法计算出的节点最大吞吐量与网络仿真结果一致,可以准确分析多速率无线Mesh网络节点吞吐量.

Abstract:

To analyze the node throughput in wireless mesh networks (WMNs) based on IEEE 802.11 under fairness guarantee, an analysis model for multi-rate WMNs is proposed. The model calculates the data transmission time on the links with different data rate, and looks for the bottleneck collision domain (BCD) where the offered load was transmitted with the longest time. When the offered load in BCD is given, the value of largest node throughput can be achieved. The analysis value is according with the simulations results, and the model can analyze the node throughput in multi-rate WMNs accurately.

Key words: wireless mesh networks, node throughput, multi-rate
