Route Capacity Estimation Based Admission Control and QoS Routing for Mesh Networks

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, we provide a mathematical model to analyze and estimate the real-time "route capacity" associated with time-varying QoS requirements. This allows us to take admission control decisions for new data flows in a way that we can increase the resource utilization while maintaining...
