The embodiment of the invention provides a wireless network scheduling method and device. When nodes in a wireless network access at least one type of applications, the wireless network scheduling device comprises a first obtaining unit which is used for obtaining parameters corresponding to each type of applications, wherein the parameters represent data packet attributes of each type of applications, and the parameters corresponding to different types of applications are the same in type; a first determination unit which is used for determining a mapping relationship of transmission conditions and transmission modes for transmitting the applications according to the parameters; and a first transmission unit which is used for transmitting the mapping relationship to the nodes needing to obtain the mapping relationship. Through application of the device provided by the embodiment, when network application demands are changed, centralized scheduling is carried out on the nodes in the network, so the nodes can access various different application types, diversified application demands are satisfied, network residual resources are balanced, and the access states of the nodes and application transmission states are changed flexibly.
