Sensor networking method and sensor network adopting same

Abstract

The invention discloses a sensor networking method and a sensor network adopting the same. The sensor networking method comprises the following sequence steps of: s1, carrying out device initialization on a base station, and carrying out device initialization on terminals; s2. By the base station, scanning a preset frequency band, and inviting the terminals in the preset frequency band, which work under different frequencies, to access a network; and s3, by the base station, according to a network access sequence of the terminals in the network, allocating working time slots to the terminals which access the network. Therefore, each terminal in the network works under the different frequency and has the independent working time slot; channel stability and anti-interference capacity of wireless communication between the base station and the terminals are ensured; real-time performance of data is improved; the defects of low real-time performance and inconvenience for expansion in an existing sensor network are made up; networking efficiency of sensors is improved; and meanwhile, the sensor network adopting the sensor networking method, which is disclosed by the invention, also has the same advantages.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a sensor networking method and a sensor network using the method. Background technique [0002] A wireless sensor network is generally composed of a large number of sensor nodes deployed in the monitoring area, and forms a multi-hop self-organizing network system through wireless communication. information and send it to observers. [0003] In sensor network applications, usually sensor nodes are placed where there is no network infrastructure, the location of sensor nodes cannot be precisely set in advance, and the mutual neighbor relationship between nodes is not known in advance, so sensor nodes are required to have their own An organization's ability to automate configuration and management. [0004] In the prior art, Zigbee protocol or WiFi communication protocol is mostly used to realize the ad hoc network of sensors. Due to the semi-openness of the Zigbee protocol,...

AI Technical Summary

Problems solved by technology

This strategy makes the real-time performance of the Zigbee network system poor

For products using WiFi networking, the scale of its network nodes generally does not exceed 16, which greatly limits the expansion of the network

Therefore, existing sensor networking methods have deficiencies
