Problems solved by technology

In the current wireless networking system, the functions of the sensing fulcrum and the relay fulcrum are pre-set. The sensing fulcrum is only used to collect data, and the relay fulcrum is only used to relay data. It is necessary to pre-set the network. When the monitoring environment is complex or changes, the layout of the network fulcrum needs to be readjusted. The workload is relatively cumbersome. Once the relay fulcrum is deleted or fails, the entire network transmission function will be paralyzed and data transmission cannot be completed.

Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, where the schematic embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0032] figure 2 It is a flow chart of the wireless sensor network networking method of the present invention, including steps:

[0033] S1: The gateway sends the first group of network frames;

[0034] S2: The fulcrum that can receive the first network frame joins the network as the first layer fulcrum, and then sends the second network frame; the fulcrum that receives the second network frame joins the network as the second layer fulcrum, and then sends the third group Network frame, and so on to form a multi-layer topology. The first-layer fulcrums are all connected to the gateway, and each first-layer fulcrum sends out its own second networking frame, and the second-layer fulcrum re...

Abstract

The invention relates to the field of wireless sensor networks, and discloses a networking method comprising the following steps: S1: a gateway sends a first set of network frames; S2: a pivot capable of receiving the first set of network frames is added into a network to serve as a first-layer pivot, and then sends a second set of network frames; the pivot receiving the second set of network frames is added into the network to serve as a second-layer pivot and then sends a third set of network frames and so on, and thus a multi-layer topology is formed; S3: and if a preset condition is met, networking is completed. According to the method provided by the invention, the wireless sensor network can be more flexibly configured in a dynamically variable multi-layer topology networking manner, and the network is more prone to be expanded.

Description

technical field [0001] The invention relates to wireless sensor network technology, in particular to a wireless sensor network networking method. Background technique [0002] The wireless sensor network is composed of a large number of miniature sensor fulcrums deployed in the monitoring area. It forms a multi-hop self-organizing network system through wireless communication. It is widely used in many fields such as intelligent transportation, environmental monitoring, and medical care. . Existing wireless sensor networks such as figure 1 , generally the information is collected by the sensing fulcrum, and the relay fulcrum is responsible for collecting the information and relaying it to the data processing equipment for data processing. In the current wireless networking system, the functions of the sensing fulcrum and the relay fulcrum are pre-set. The sensing fulcrum is only used to collect data, and the relay fulcrum is only used to relay data. It is necessary to pre...
