基于6LoBLE的低功耗蓝牙网状网络邻居发现机制研究

Bluetooth Low energy based on IPv6 (6LoBLE) can realize the seamless connection between bluetooth devices and the Internet, break the situation that Bluetooth application is under restrictions as short distance communication solution, and advance the development of application of the Internet of things. However, International standard organization like IETF and Bluetooth SIG, and related research in home and overseas are still failed to make an efficient method for Bluetooth Low Energy(BLE) mesh networking. This project is based on 6LoBLE technology, focusing on the three key technologies, IPv6 address configuration, the parameter adaptive model for neighbor discovery and mesh network flooding routing to research Bluetooth Low Energy IPv6 mesh network neighbor discovery mechanism. Introducing the theory of algorithm design, Chinese Remainder Theorem and the capture effect in wireless network, put forward a kind of stateless address autoconfiguration mechanism based on virtual coordinate, a parameter adjustment model of neighbors discovery based on 6 LoBLE and a BLEmesh routing method based on capture effect. The proposed mechanism is expected to be innovative and high reliability, and expected to change current situation that the BLE does not support mesh network, meanwhile, provide a practical guideline for the connectivity between BLE and the Internet and promote the development of application for BLE in Internet of things.
