Abstract: A method can be used for channel mapping based on frequency hopping. A working channel label of a node is computed according to the number of working channels of the node in frequency hopping mode, an identifier of the node, and a time parameter corresponding to a current superframe. A working channel is determined according to the working channel label. Data is transmitted on the working channel within the current superframe.

Abstract: Embodiments of the present invention provide a node control method, a network controller, and a network system. The node control method includes: constructing a wake-up frame, where the wake-up frame includes wake-up indication information of a node to be woken up; and sending, in an inactive period of a superframe structure, the wake-up frame according to preset sending time, so that a node that obtains, by listening, the wake-up frame performs data exchange with a network controller when it is determined, according to the wake-up indication information, that the node that obtains, by listening, the wake-up frame is the node to be woken up. A wake-up frame may be sent in an inactive period of a superframe structure to implement data communication between a node and a network controller, which increases a length of the superframe structure and can meet a requirement for data uploading by the node.
