Embodiment Construction

[0034] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and processes are provided, but the protection scope of the present invention is not limited to the following implementations example.

[0035] In this embodiment, Bluetooth devices are first classified according to the classification standards of Bluetooth devices, and then the connection mode between Bluetooth devices is modified to ensure that only similar Bluetooth devices within the communication range (that is, the distance is less than 10 meters) can be connected, and the Bluetooth devices are formed into individual isolated devices. scatternet, and determine the super nodes in each isolated scatternet, and finally choose a Bluetooth device that is different from the Bluetooth device to be networked as a bridg...

Abstract

The invention relates to an automatic classification networking method for Bluetooth devices in the technical field of wireless communications, wherein, the method comprises the following steps: the Bluetooth devices are classified according to the classification standard of the Bluetooth devices; the Bluetooth devices are connected within the communication scope and then obtaining attribute information of the counterpart for verifying that whether the Bluetooth devices belong to the same class, and if yes, the Bluetooth devices are connected; if no, the Bluetooth devices are disconnected. Thus, the Bluetooth devices belonging to the same class in the communication scope are connected and combined into a plurality of isolated scattering networks. A super peer in each isolated scattering network is determined for marking the scattering network. Each isolated scattering network sends out a detecting message. Bluetooth devices which are different from the Bluetooth devices for networking are selected as bridge access points for connecting the scattering networks in the region to form a global network. With the least quantity of the scattering networks, the method can not only ensure the connectivity, but also improve the average transmitting speed, reduce the energy consumption of the whole scattering network, etc.

Description

technical field [0001] The present invention relates to a method in the technical field of wireless communication, in particular to a method for automatic classification and networking of bluetooth devices. Background technique [0002] Bluetooth technology is a global short-distance wireless communication technology, which is widely used in various fields of short-distance real-time wireless communication. According to the distance of the transmission distance (currently mainly the transmission distance of 1 meter, 10 meters and 100 meters), Bluetooth is divided into category 1, category 2 and category 3 accordingly. As the supported distance increases, the energy consumed by Bluetooth devices is also rising. Therefore, most commonly used Bluetooth devices are category 2. Bluetooth is free to use because it operates in the 2.4GHz band, a license-free Industrial, Scientific and Medical (ISM) radio band. At the same time, Bluetooth adopts forward error correction, coding o...
