Embodiment 1

[0041] This embodiment provides a wireless Mesh node, such as figure 1 As shown, the wireless Mesh node 100 includes: a core unit 110 , a receiving unit 120 , a sending unit 130 , and a sending clock 140 .

[0042] The kernel unit 110 has a built-in operating system, which periodically collects the latest state information of the link connected to the wireless Mesh node itself and the IP address of the adjacent wireless Mesh node at the other end of the link; The state information is the link state information of the wireless Mesh node. Specifically, the operating system in the wireless Mesh node 100 collects the latest link status information connected to the wireless Mesh node through a private protocol, and forwards link information and IP addresses from adjacent wireless Mesh nodes at the same time. The private protocol refers to a protocol created privately and not disclosed to the public. It may be an existing network protocol or a protocol created by the developer itse...

Embodiment 2

[0048] This embodiment provides a network topology discovery system for wireless Mesh nodes, such as figure 2 As shown, the network topology discovery system 200 of the wireless Mesh nodes includes: a wireless Mesh network 210 composed of wireless Mesh nodes 211 and a monitor 220, and the monitor 220 is connected to a wireless Mesh node 211 in the wireless Mesh network 210 .

[0049] The wireless Mesh node 211 includes: a core unit, a receiving unit, a sending unit, and a sending clock.

[0050] The built-in operating system of the kernel unit periodically collects the latest status information of the link connected to the wireless Mesh node itself and the IP address of the adjacent wireless Mesh node at the other end of the link; the status of the link connected to the wireless Mesh node itself The information is the link state information of the wireless Mesh node. Specifically, the operating system in the wireless Mesh node collects the latest link state information conn...

Abstract

The invention provides a system and a method for finding a wireless node and a network topology structure of the wireless node. A wireless Mesh node comprises a kernel unit, a receiving unit and a transmitting unit, wherein the kernel unit is internally provided with an operation system and is used for periodically collecting the latest state information of a link which is connected with the wireless Mesh node and IP addresses of adjacent wireless Mesh nodes at the other end of the link; the state information of the link which is connected with the wireless Mesh node is link state information of the wireless Mesh node; the receiving unit is connected with the kernel unit and is used for receiving the link state information and IP addresses of the adjacent Mesh nodes; the transmitting unit is connected with the kernel unit and is used for periodically broadcasting link state information and IP addresses of the wireless Mesh nodes and forwarding the link state information and the IP addresses of the adjacent Mesh nodes. The system and the method can be used for monitoring and managing link state of the wireless Mesh node, displaying the topology structure of a wireless Mesh network and controlling the change of the wireless Mesh network topology structure in real time.

Description

technical field [0001] The invention belongs to the technical field of wireless networks, and relates to a wireless node monitoring system, in particular to a wireless Mesh node and its network topology discovery system and method. Background technique [0002] Wireless Mesh network, namely "mesh network", is a wireless broadband access technology based on IP protocol. It combines the advantages of WLAN and Ad hoc network, supports multipoint-to-multipoint mesh structure, and has self-organizing and self-repairing functions. , multiple cascading, node self-management and other functional advantages, as well as mobile broadband, wireless positioning and other characteristics, it is a network with large capacity, high speed and wide coverage, and has become an effective means of broadband access. In a sense, the Mesh network is mainly a kind of network architecture idea, and its main functions are reflected in the centerless, self-organizing network, multi-level jumping and ro...
