Method for synchronously processing networks in wireless MESH network

Abstract

The invention discloses a method for synchronously processing networks in a media access control layer of a wireless MESH network. The method mainly comprises the following steps of: performing initial network synchronization and repeat network synchronization, wherein the initial network synchronization is performed after a node is powered on, and the repeat network synchronization is performed after nodes are transformed from a synchronizing state to a desynchronizing state; and the initial network synchronization is divided into two processing modes, one is network synchronization when a new access node is initially powered on after the MESH network is built, namely a new node synchronizing process, and the other is the synchronization when a plurality of nodes are simultaneously powered on and the MESH network is not build, namely a multiple node simultaneous starting process. The method has the advantages that: by the network synchronization processing method in the media access control layer of the wireless MESH network, a synchronization processing method of the complete media access control layer in the wireless MESH network is provided, and defects that application scenesare not sufficiently supported by the conventional wireless MESH network synchronization technology when the plurality of nodes are simultaneously powered on and the like are overcome.

Description

technical field [0001] The invention relates to a synchronization technology in a wireless MESH network, in particular to a network synchronization processing method in a media access control layer of the wireless MESH network. Background technique [0002] Synchronization technology is the key technology in the wireless MESH network and the basis of the communication between the nodes of the whole system. Only by keeping the synchronization between each node can the whole system communicate normally. Synchronization technology includes physical layer synchronization and network synchronization of media access control layer. Physical layer synchronization is to realize bit-level synchronization when data is sent and received, which can ensure that information is received correctly by bit; network synchronization of media access control layer is to maintain system Frame synchronization, through network synchronization, MESH nodes can know the current frame number in the netwo...

AI Technical Summary

Problems solved by technology

The existing MESH network synchronization technology is mainly aimed at the network synchronization process of other nodes after the central node in the MESH network has been working normally. This type of method is not suitable for the synchronization processing scenario when multiple nodes are powered on at the same time.
