Problems solved by technology

[0003] The current connection method of Bluetooth devices in the home is that the handheld terminal directly matches and connects with the Bluetooth device to control the Bluetooth device; that is to say, the current Bluetooth device network is single and chaotic, and there are multiple Bluetooth signals that are always scanning the terminal. To achieve the matching effect, this will occupy a large number of signal frequency bands, and the Bluetooth signals also interfere with each other, resulting in interference in the control of the Bluetooth device by the handheld terminal, seriously affecting the normal use of the Bluetooth device, and also affecting other wireless devices

Embodiment 1

[0048] This embodiment provides a method for ad hoc networking of Bluetooth devices, such as figure 1 shown, including:

[0049] Step S10: Receive the key for self-organizing network authentication, so as to perform authentication between Bluetooth devices and match the self-organizing network.

[0050] In this step, each bluetooth device has a unique identity id, and the bluetooth device is initialized through a handheld terminal (such as a mobile phone), and a key for a bluetooth device ad hoc network authentication is set at the same time, and the key is sent to Individual Bluetooth devices. When broadcasting between Bluetooth devices, the key certified by the ad hoc network can be matched with the ad hoc network.

[0051] Step S11: Calculate the distance between any two Bluetooth devices according to the received signal strength between any two Bluetooth devices.

[0052] In this step, the distance calculation between any two bluetooth devices is to prepare for the subs...

Embodiment 2

[0061] This embodiment provides a method for ad hoc networking of Bluetooth devices, such as figure 2 shown, including:

[0062] Step S10: Receive the key for self-organizing network authentication, so as to perform authentication between Bluetooth devices and match the self-organizing network.

[0063] In this step, each bluetooth device has a unique identity id, and the bluetooth device is initialized through a handheld terminal (such as a mobile phone), and a key for a bluetooth device ad hoc network authentication is set at the same time, and the key is sent to Individual Bluetooth devices. When broadcasting between Bluetooth devices, the key certified by the ad hoc network can be matched with the ad hoc network.

[0064] Step S11: Calculate the distance between any two Bluetooth devices according to the received signal strength between any two Bluetooth devices.

[0065] In this step, the distance calculation between any two bluetooth devices is to prepare for the sub...

Embodiment 3

[0098]Based on the Bluetooth device ad hoc network method in Embodiment 1 and 2, this embodiment provides a Bluetooth device ad hoc network system, such as image 3 As shown, it includes: a receiving module 1, which is used to receive the key for ad hoc network authentication, so as to perform authentication between Bluetooth devices and match the ad hoc network. The calculation module 2 is used to calculate the distance between any two Bluetooth devices according to the received signal strength between any two Bluetooth devices. The planning module 3 is used to plan the shortest path for connecting the Bluetooth devices to the ad hoc network according to the minimum distance between the Bluetooth devices. The ad hoc network module 4 is used for performing ad hoc network connection of bluetooth devices according to the shortest path.

[0099] By setting up the planning module 3, the single and chaotic networking of multiple Bluetooth devices has been successfully solved, and ...

Abstract

The invention provides a Bluetooth device ad hoc network method and system. The method comprises steps: a key for ad hoc network authentication is received to carry out ad hoc network match authentication between Bluetooth devices; according to the receiving signal strength between any two Bluetooth devices, the distance between any two Bluetooth devices is calculated; according to the minimum distance between the Bluetooth devices, the shortest path line for Bluetooth device ad hoc network connection is planned; and according to the shortest path line, Bluetooth device ad hoc network connection is carried out. According to the Bluetooth device ad hoc network method and system provided in the invention, single and disorderly networking among multiple Bluetooth devices at present is solvedsuccessfully, the occupancy rate of a signal frequency band is reduced, mutual interference between Bluetooth signals is thus reduced or avoided, interference of the Bluetooth signals to other wireless signals is also reduced or avoided, the control stability among multiple Bluetooth devices is thus ensured, and better and more qualified service can further be provided for the user.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for ad hoc networking of Bluetooth devices. Background technique [0002] The existing smart home system is mainly composed of an intranet, a gateway and an extranet. The intranet is mainly to connect various devices and home appliances at home, that is, the home intranet. Many home intranets are still connected through wired methods. The wired connection has the disadvantages of difficult wiring and high cost. The home intranet is established through wireless methods. appears to be particularly important. At present, wireless methods such as wireless wifi and zigbee have many disadvantages. For example, wifi has disadvantages such as relatively high price, relatively high power consumption, poor mobility, and difficult networking; zigbee has difficulties in promotion, relatively high cost, and relatively slow transmission rate. and other shor...
