Embodiment Construction

[0021] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] figure 2 Shown is a WiFi wireless broadband sensor network topology according to a specific embodiment of the present invention.

[0023] Such as figure 2 As shown, a sensor gateway including a communication connection device according to an embodiment of the present invention is located at the root of this tree network topology. The sensor gateway is connected downward with the first-level sensor cluster head to form a point-to-point communication group; upwardly, it can be connected with the telecommunications network or other local area networks through various wired or wireless network connection technologies.

[0024] The sensor cluster head including the communication connection device of a specific embodiment of the present invention is divided into multiple layers, located between the root and leaf nodes of the tree top...

Abstract

The invention relates to the technical field of information and communications and provides a networking method and devices of a wireless broadband sensor network. The networking method is characterized in that a sensor gateway, sensor cluster heads and sensor nodes are connected by a WiFi point-to-point technology and jointly form a tree network structure used for sensor network data communication; the sensor gateway is the root node of the tree network structure and serves as an interface for connecting the sensor network and an external network; as the intermediate nodes of the tree network structure, the sensor cluster heads can be divided into a plurality of levels; and the leaf nodes of the tree network structure are the common sensor nodes. By adopting the scheme in the invention, the WiFi sensor nodes can form the large-scale wireless broadband sensor network through the rapid ad hoc network scheme under the condition of not having the pre-deployed and completely covered WiFi network so as to provide real-time sensor network services for various industries under various environmental conditions.

Description

technical field [0001] The invention relates to the field of information and communication technologies, in particular to a networking method and related devices for a wireless broadband sensor network. Background technique [0002] In recent years, countries around the world have proposed strategies such as "Smart Earth", "Smart China", and "Smart City" around sensor network technology. Sensor network technology and application will become one of the most influential technologies in the 21st century. [0003] At present, the most typical communication method of wireless sensor network is Zigbee technology. Zigbee technology can meet the low-bandwidth and short-distance communication requirements between low-power sensor nodes. But Zigbee technology is not suitable for high-bandwidth sensing information transmission. With the maturity of low-power WiFi technology, WiFi can already be used as a communication technology for wireless sensor networks. Since WiFi is a high-ba...
