Connection admission control and grade of service for QoS routing in mesh networks

—Wireless mesh networks (WMNs) is a promising key technology for next generation wireless backhauling that have recently attracted both the academic and industrial interest. Such networks are expected to have high throughput demands and support various types of applications with different qualityof-service (QoS) constraints. Opportunistic scheduling has been proven highly beneficial in such networks since it takes advantage of the dynamic nature of the channel between different wireless mesh routers. Recently a promising cross-layered framework has been proposed (IQoSR, [1], [2]) that combines a distributed opportunistic scheduler with a multi-constrained QoS routing scheme and has been proven to outperform conventional layer 2 and 3 approaches. However, opportunistic scheduling cannot provide hard resource reservation; therefore, the admission of new flows in a route may jeopardize the QoS of the ongoing flows. In order to overcome this problem, in this work we introduce a connec...
