Method, device and system for establishing tree topology of wireless communication multi-hop network device

Abstract

The invention provides a method, device and system for establishing the tree topology of a wireless communication multi-hop network device and relates to the field of wireless communication. By the adoption of the method, device and system for establishing the tree topology of the wireless communication multi-hop network device, automatic identification of the topological structure of a wireless node device in a coverage area is achieved. The method comprises the steps that when at least one node to have access to the wireless communication multi-hop network selects an accessible node in the wireless communication multi-hop network and uses the accessible node as a father node, the accessible node and the nodes to have access to the wireless communication multi-hop network conduct hand shaking; the accessible node and the nodes to have access to the wireless communication multi-hop network conduct link maintaining information interaction, and the accessible node receives link maintaining information and monitoring information which are reported by the nodes to have access to the wireless communication multi-hop network; according to the monitoring information, the accessible node selects one or more nodes from the nodes which are about to have access to the wireless communication multi-hop network and select the accessible node as the father node, the selected nodes to have access to the wireless communication multi-hop network serve as next-level sub-nodes of the accessible node, and then a judgment result of access to the topology is generated. The method, device and system are suitable for the wireless communication multi-hop network, and the topology structure in the wireless communication multi-hop network is established.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a tree topology construction method, device and system for wireless communication multi-hop network equipment. Background technique [0002] Network topology construction is one of the basic conditions for realizing network management functions. Network topology information can be used to monitor and manage wireless network connectivity, obtain routing information, search for network bottlenecks, and assist wireless air interface resource allocation. It is important information to help users make decisions and realize network control, management, and maintenance. [0003] Due to the requirements of the wireless coverage area of ​​the chain or tree network, there are often multiple wireless node devices in the wireless coverage area of ​​the access point, and these wireless node devices will present various topological structures in terms of adjacency. How to automat...
