Bandwidth Measurement in Wireless Mesh Networks

In this project, we investigate the issue of measuring endto-end bandwidth in wireless mesh networks. Bandwidth measurement is an active research topic in the networking area as the information of link capacity and available bandwidth is essential for the network management, traffic control, and QoS provisioning. Although quite a few research progresses have been made in the wired networks, the bandwidth measurement in the wireless mesh networks is yet to be explored. In the latter domain, we need to face totally new challenges including cross-traffic interference and multihop effect. To design and evaluate measuring tools, we have set up a testbed of wireless mesh network. Our goal is to analyze those factors via real testing environment and to propose relevant techniques on the basis of what we have observed from the experiments.
