Low-power Bluetooth IPv6 address automatic configuration method based on 6LoBLE

Abstract

The invention discloses a low-power Bluetooth IPv6 address automatic configuration method based on 6LoBLE. The low-power Bluetooth IPv6 address automatic configuration method is implemented based on alow-power Bluetooth neighbor discovery protocol, and applied to the communication connection between low-power Bluetooth equipment and Internet equipment. Communication equipment comprises broadcasting equipment, scanning equipment and the Internet equipment; and the broadcasting equipment and the scanning equipment are both low-power Bluetooth equipment. The method comprises a connection processof the broadcasting equipment and the scanning equipment, and an IPv6 address configuration process of the scanning equipment; the connection process of the broadcasting equipment and the scanning equipment is as follows: transmitting a header of a broadcast data packet and a header ADV-EXT-IND data packet of an extended broadcast data packet on a main broadcast channel to the scanning equipmentby the broadcasting equipment, and completing the reception of a Connect-Req data packet on a transmission channel by the scanning equipment according to the transmission time of a specified payload to realize connection; and the IPv6 address configuration process comprises the establishment of the connection, address registration, 6LoBLE communication and prefix updating. The low-power BluetoothIPv6 address automatic configuration method based on the 6LoBLE provided by the invention has an important promoting effect on smart home, Internet of Vehicles and adapting to fast moving Internet ofThings applications.

Description

technical field [0001] The invention relates to an IPv6 address configuration method between a bluetooth device and the Internet, in particular to a 6LoBLE (IPv6over BLE, bluetooth technology with low power consumption) automatic bluetooth IPv6 address configuration method. Background technique [0002] Bluetooth Low Energy is a low-power, low-latency Bluetooth communication technology proposed by the Bluetooth Special Interest Group (BluetoothSIG) when Bluetooth 4.0 was released. IPv6-based Bluetooth low energy technology (IPv6over BLE, 6LoBLE) is an important technology that supports low-power Bluetooth devices to transmit IPv6 data packets, and its purpose is to achieve seamless connection between low-power Bluetooth devices and the Internet; and Since the low-power bluetooth technology is a short-distance, low-latency and low-power data transmission technology, it is widely used in the fields of smart home, crowd sensing, car networking and personal medical health monito...
