Abstract: | First, the basic situation of wireless mesh networks was briefly reviewed, and the necessity and significance of providing QoS guarantees for such networks were analyzed. Then, we classified the QoS provisioning techniques in the lowest three protocol layers (i. e. physical layer, MAC layer and routing layer) of wireless mesh networks and the cross-layer design techniques, and systematically introduced their research developments. Finally, some problems and research directions of these QoS provisioning techniques were given. |
