Abstract

Embodiments of the present invention provide a data transmission method and a relay node. The data transmission method of the present invention includes: the first relay node receives data; the first relay node determines the target site of the data according to the neighbor node information of the first relay node; the first relay node sends the data to the target site. The embodiment of the present invention can shorten the data transmission path between sites, improve the data transmission efficiency, and reduce the network overhead in the data transmission process.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a data transmission method and a relay node. Background technique [0002] As a currently popular wireless network, a tree (Tree) network can be widely used in Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, IEEE for short) 802.11ah. The structure of the tree network is derived from the most basic star (Star) network structure in the wireless network, and the star network structure is also the most basic structure of the current Wireless-Fidelity (Wireless-Fidelity, WiFi) network. As the root node of the star network, the access point (AccessPoint, referred to as AP) is responsible for data exchange with its associated station (Station, referred to as STA), and data transmission between the station and the distributed system (Distributed System, referred to as DS). , and communication relay between sites...
