Wireless sensor networking method applied to data transmission of internet of things

Abstract

The invention relates to a wireless sensor networking method applied to data transmission of an internet of things. In the wireless sensor networking method, firstly, a center node and child nodes in a wireless sensor network are electrified and initialized; the center node sends a networking beacon by the center node for starting to enter a networking stage; the child nodes add a PanID (Personal Area Network Identifier), a short address and an expansion address of a source node, sending a beacon frame, to a neighbor table of the child nodes, record the field intensity information of the received beacon frame, store a forwarding node in a neighbor node list, and record the field intensity of the forwarding node; then the center node collects the field intensity information of nodes in a region, plans a node route according to the collected field intensity information, and configures the child nodes; and after the center node configures the child nodes, the wireless sensor network enters a normal working stage for realizing data transmission of the internet of things.

Description

technical field [0001] The invention relates to the field of wireless sensor networks, in particular to a wireless sensor network networking method applied to the data transmission of the Internet of Things. Background technique [0002] The sensor network is a distributed intelligent network system that is composed of a large number of tiny sensor nodes with wireless communication and computing capabilities deployed in the active area through self-organization and can independently complete specified tasks according to the environment. The distance between the nodes of the sensor network is very short, and the multi-hop wireless communication method is generally used for communication. Sensor networks can operate in a stand-alone environment or be connected to the Internet through a gateway, allowing users to access them remotely. The sensor network integrates sensor technology, embedded computing technology, modern network and wireless communication technology, distribute...

Problems solved by technology

[0006] In the current existing technology, there is no specific networking method for wireless sensor networks with relatively fixed node positions and periodic data transmission. It is a large number of assumptions that a large number of nodes are randomly scattered at the monitoring site to design the network. method, when this networking method is applied to the data transmission field of Internet of Things applications such as electricity consumption information collection of power users, centralized meter reading of water meters and gas meters, industrial wireless data collection, environmental monitoring, logistics and warehousing, etc., there will be line-of-sight transmission Limitations, and manual intervention is required in the networking process, and the success rate of copying data information cannot be guaranteed, etc.
