Abstract
A media access controller (MAC) for wireless mesh networks comprises a quality-of-service (QoS) manager to monitor consumed bandwidth of a current application flow and to compare the consumed bandwidth with a contracted bandwidth for the current application flow. The MAC also comprises a contention manager to coordinate access to a wireless communication channel for communications with other nodes of the wireless mesh network. The QoS manager instructs the contention manager to employ signaling to request additional resources for the current application flow after the consumed bandwidth is significantly less than the contracted bandwidth.
