Crosslayer makes use of adaptive technology which can adapt the change of channel, it satisfied both the using of wireless rescource utilization and the Qos needs of multimedia services. The background, signalling Interactions, cases and development are included in this paper.[Keywords] Wireless mesh network Ad Hoc Crosslayer Adaptive protocol第11頁，共11頁
