Abstract

An embodiment of the invention provides a node control method, a network controller and a network system. The node control method comprises constructing a wake-up frame which comprises wake-up indication information of nodes to be waken up, sending the wake-up frame in an inactive phase of an ultra frame structure according to preset sending time to conveniently monitor the nodes of the wake-up frame; and conducting data interaction with the network controller when the nodes to be waken up are determined according to the wake-up indication information. The embodiment of the invention further provides the network controller and the network system. The technical scheme of the embodiment can send the wake-up frame in the inactive phase of the ultra frame structure, achieve data communication between the nodes and the network controller, accordingly increase the length of the ultra frame structure, and meet requirements for uploading data of the nodes.

Description

technical field [0001] The embodiments of the present invention relate to network technologies, and in particular to a node control method, a network controller and a network system. Background technique [0002] In wireless sensor networks, nodes are usually powered by their own power supply. Since the energy of the self-contained power supply is limited, it is necessary to manage or control the energy consumption of nodes in the network to improve the life cycle of nodes and the entire network. Wherein, in the energy management of the network nodes, the nodes are usually controlled by periodically waking up the nodes. [0003] In the prior art, a node control method using a superframe mechanism is proposed for low-speed wireless personal area networks. The method uses the superframe structure to control nodes, and the network controller periodically Broadcast beacon frames to nodes in the network, each node in the network also periodically wakes up and receives beacon fra...
