Other AbstractThe invention relates to a clustering-wireless-sensor-network-orientated two-stage adaptive frequency-hopping method. The method comprises the following steps of: constructing the clustering wireless sensor network defining a super-frame structure based on institute of electrical and electronic engineer (IEEE) 802.15.4 according to the topological structure of the clustering wireless sensor network accessing a format of a beacon frame of a control layer based on a medium of the original IEEE 802.15.4, and extending a content of a beacon frame load and accessing the beacon frame of the control layer based on the super-frame structure and the extended medium of the IEEE 802.15.4 so as to realize a two-stage adaptive frequency-hopping process of a node in the network. By the clustering wireless sensor network, the network size is expanded, the difficulty in maintenance and management is lowered, and the system flexibility is improved as the two-stage frequency-hopping method is designed, the compatibility with the IEEE 802.15.4 and the system reliability are guaranteed and based on the beacon frame load of the IEEE 802.15.4, no special frame is not needed to be designed for a broadcast channel distribution result during a channel switching process, so that the network design is simplified, the number of the frames for controlling is reduced, and the network throughput is increased.
