Problems solved by technology

The invention with the application number CN201310634145.2 discloses a networking method of a micro-power wireless communication network. The micro-power wireless communication network includes a central node and several sub-nodes, including the following steps: the central node sends the first hop Networking message; confirm that the child node of the first hop is connected to the network; the first hop is added to the network; then, the central node sends the second hop network message; the central node sends the third hop network message; and so on , the central node sends out the networking message of the z-th hop, the whole networking process takes a lot of time and consumes a lot of power

Embodiment 1

[0022] The wireless communication network system of the present invention is generally applicable to wireless meter reading, industrial telemetry, remote control, automatic data collection, building automation, machine room equipment monitoring, security, access control systems, wireless keyboards, wireless mice, underwater positioning, alarms, etc. Industrial and civil equipment.

[0023] see figure 1 As shown, the present invention divides the communication nodes in the network into central nodes and sub-nodes, and logically divides the sub-nodes in the network into different communication levels, and identifies backbone nodes and regular nodes in each logical layer. Such as figure 1 First-level backbone nodes, second-level backbone nodes, ..., N-level backbone nodes; first-level regular nodes, second-level routing communication reachable regular nodes, ..., N level routing communication reachable regular nodes. The system forms a network according to the network configura...

Embodiment 2

[0039] like figure 2 As shown, a networking method of a micro-power wireless communication network uses a network including a central node and several sub-nodes; the sub-nodes are set as backbone nodes and regular nodes; the node type information of the backbone nodes and regular nodes is carried out by the central node Maintenance; the central node initiates a networking command, and the backbone node replies to related information such as field strength after receiving the networking command, and continues to forward the networking command to the air; after the regular node receives the networking command, it replies to field strength, etc. Relevant information and enter the dormant state, no longer forward networking commands to the air.

[0040] The central node initiates a networking command, and a timer is started at the same time. After the timer ends, the beacon sending process ends; the field strength collection phase starts after the beacon sending process ends.

Abstract

The invention discloses a networking method of a wireless communication network. The wireless communication network consists of a center node and a plurality of sub nodes; meanwhile, the sub nodes in the network are subjected to different communication layers of logic division, and in each logic layer, backbone nodes and conventional nodes are identified; a system carries out networking according to network configuration; and the networking method comprises steps of beacon transmission, field strength collection and parameter configuration, wherein the center node carries out management allocation on received field strength information and corresponding node types according to a set network access field strength threshold, forms communication routing information of directly carrying out communication reachability, carrying out communication reachability by primary backbone nodes, carrying out communication reachability by secondary nodes and the like, and carries out management maintenance on the routing information. By using the center node to set up a basic network in a mode of managing a backbone network, stability of the network can be ensured to a great degree, and in the other aspect, after the routing information is determined, parameter configuration can be directly executed for a great number of common nodes by the backbone nodes, and thus, network communication time is greatly saved, and network communication power consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of wireless network communication. Background technique [0002] Various micro-power short-distance radio transmission devices have penetrated into people's lives, such as the well-known cordless phones, Bluetooth, wireless local area network, vehicle distance radar, radio frequency identification, and ultra-wideband, all of which belong to the category of micro-power radio technology.
