Embodiment 1

[0031] Figure 1a It is a flow chart of a WMN-based node access control method provided by Embodiment 1 of the present invention. The node access control method provided in this embodiment is applicable to a scenario in which a new node accesses an adjacent node in a WMN. The node access control method provided in this embodiment can be executed by a WMN-based node access control device, which can be implemented in software and / or hardware, and integrated into the equipment of the node to be accessed. Wherein, the node to be accessed refers to a new node in the WMN that is ready to be accessed with other peripheral nodes.

[0032] refer to Figure 1a A WMN-based node access control method provided in this embodiment specifically includes:

[0033] S110. Obtain a broadcast message of at least one peripheral node.

[0034] All the node access control methods provided in this embodiment may be executed by a media access control layer (Media Access Control, MAC) of the node to b...

Embodiment 2

[0052] Figure 2a It is a flow chart of a WMN-based node access control method provided by Embodiment 2 of the present invention. This embodiment is embodied on the basis of the above-mentioned embodiments. Specifically, refer to Figure 2a A WMN-based node access control method provided in this embodiment specifically includes:

[0053] S210. Obtain a broadcast message of at least one peripheral node.

[0054] S220. Parse at least one broadcast message, and determine priority information of at least one peripheral node.

[0055] Exemplarily, the specific parsing manner of the broadcast message is not limited in this embodiment. After parsing at least one broadcast message, the priority information of at least one peripheral node is obtained from the broadcast message.

[0056] Wherein, the priority information includes synchronization priority and / or CQI. In this embodiment, priority information including synchronization priority and CQI is used as a preferred example f...

Embodiment 3

[0110] Figure 3a It is a flow chart of a WMN-based node access control method provided by Embodiment 3 of the present invention. This embodiment is embodied on the basis of the above-mentioned embodiments. Specifically, refer to Figure 3a A WMN-based node access control method provided in this embodiment specifically includes:

[0111] S310. Receive a node configuration message sent by the RRC.

[0112] Specifically, when the node to be accessed detects that it is powered on, the RRC of the node to be accessed configures its own node through an Ethernet message, and generates a node configuration message. Among them, the node configuration message can optionally include: configuration parameters such as the maximum number of nodes allowed by the network, bandwidth, and frequency point, and can also optionally include: configuration parameters for enabling switches with special functions such as frequency selection, authentication, and service priority . Further, the RRC...

Abstract

The invention discloses a WMN (Wireless Mesh Network)-based node accessing control method and device, equipment and a storage medium. The node accessing control method includes: acquiring a broadcastmessage of at least one neighboring node; determining a sponsor node according to the at least one broadcast message; carrying out clock synchronization with the sponsor node, and establishing a connection with the sponsor node. By adopting the above scheme, the technical problem of clock asynchrony of all nodes in a WMN of the prior art can be solved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a WMN-based node access control method and device. Background technique [0002] In a traditional wireless local area network, each client needs to access the network through a wireless link connected to an access point (Access Point, AP). When communicating, the client must first visit a fixed access node. At the same time, each node in the network must first visit the centralized access node when communicating with each other. When the access node traffic is too large, it will lead to congestion, reducing the communication speed and communication quality. Therefore, people's demand for access to a widely existing network is becoming more and more urgent. [0003] A Wireless Mesh Network (WMN) is a network in which any wireless device node can serve as an access node and a router. Each node in the WMN can be connected to any reachable node in the netwo...
