Capacity of wireless Mesh network is sensitive with some QoS parameters, such as delay, bandwidth, hops etc. Thus, routing protocol design considers multiple QoS constraints. This paper proposed a multiQoS constrainted model which was based on fuzzy state information. Presented a routing discovery strategy with a translation between multicomputing of hop, delay, etc and only bandwidth computing. Due to the states was nonfixity, not only the QoS parameters should be estimated, but also the system variables that were estimated according to the observed information of noise. Provided the recursion which jointed the QoS parameters and state variable. It completed the complicated routing computing by lower data processing. It reduced costs of computing and maintains. And got a multiQoSoptimize routing. ......
