Wireless Mesh Networks (WMNs) is a promising key technology for next generation wireless backhauling that is expected to support various types of applications with different Quality-of-Service (QoS) demands. Advanced antenna techniques, novel scheduling algorithms and routing schemes have attracted increased research interests aiming to optimize the performance of WMNs and satisfy their vast and diverse traffic requirements. However, in such networks, uncontrolled admission of arbitrary large number of data flows, together with the distributed and dynamic nature of WMNs, can highly increase the wireless channel interference with catastrophic subsequence for the whole network. To overcome this difficulty, authors provide a mathematical model to analyze and estimate the real-time "Route capacity" associated with time-varying QoS requirements.
