As wireless communication gains more advancement, significant research has been developed and adapted to support real time transmission which strengthens quality of services. Wireless mesh networks (WMNs) are considered as the next step towards providing a high-bandwidth network over a specific coverage area. Because of their advantages over other wireless networks, WMNs are undergoing rapid progress and inspiring numerous multimedia applications such as video and audio real-time applications. These applications usually require time-bounded service and bandwidth guarantee. Therefore, there is a vital need to provide Quality of Service (QoS) support in order to assure better quality delivery. In communication this technology are accepted to provide a wide variety of real time application, hence there is a QoS is need to be maintained. One of the key mechanism is to support quality of service in traffic regulation at network state e.g. Load in order to adapt the rate flow. In this paper we proposed a novel model called fuzzy wireless mesh network, used to implement traffic adaptation in wireless mesh network. The objective of this model is to calculate the rate adaptation according to current network state. It depends on two parameter 1) Packet delay between source and destination, 2) buffer occupancy of network nodes
