Embodiment Construction

[0024] Taking the wireless ad hoc network construction method of the present invention applied to the wireless ad hoc network for centralized meter reading by users as an example, its conventional structure is as follows figure 1 As shown, the wireless self-organizing network construction method of the present invention adopts a distributed routing scheme for optimization, that is, both the central master node and the slave nodes have mastered some network reachable node exit table information, and the information table can be updated in real time as the environment changes. Update, so when end-to-end nodes exchange information, they can perform distributed routing selection and intelligent switching of abnormal routes based on the slave node's own information, which greatly improves communication efficiency.

[0025] Such as figure 2 Shown, a kind of wireless ad hoc network construction method comprises steps:

[0026] S100: Traversing the nodes of the entire network, ident...

Abstract

The present invention provides a method and system for constructing a wireless self-organizing network, which traverses the nodes of the entire network, identifies all whitelist nodes in the nodes of the entire network, and sends addresses in the network of the nodes of the entire network when no network address is allocated to the nodes of the entire network. Collect and establish the neighbor table information and distributed routing table of nodes in the entire network, control the slave nodes in the whitelist that have not successfully entered the network to perform the best-effort discovery process, update the neighbor table information and distributed routing table, according to the updated neighbor table information and distribution routing table to build a wireless ad hoc network. In the whole process, based on the neighbor table information and distributed routing table of the nodes in the whole network, a wireless communication network is established to establish the connection between the master node and each slave node through multi-hop distributed routing. Distributed routing is adopted between each node Instead of passively forwarding data, the wireless communication network constructed can realize efficient communication.

Description

technical field [0001] The invention relates to the technical field of wireless network construction, in particular to a wireless self-organizing network construction method and system. Background technique [0002] With the vigorous development of public utilities in China, ordinary people have put forward higher requirements for the living environment; encouraged by government policies, home automation has developed rapidly. As a link in the intelligent industrial chain - intelligent meter reading system has also been vigorously developed. The traditional manual meter reading method is time-consuming and laborious, and the accuracy and timeliness cannot be guaranteed, and there will be some unpleasant embarrassing situations between the meter reader and the user, which is no longer suitable for the development needs of the society. This also puts forward higher requirements for meter reading, so we propose wireless meter reading. [0003] In wireless meter reading techno...
