摘　　要：由于传统蓝牙组网过程繁琐,造成其不能很好应用于智能家居网络中,针对此问题提出一种基于低功耗有损网络路由协议的蓝牙组网技术(routing protocol for LLN in Bluetooth networking,RPL-BN)。将基于RPL的蓝牙组网应用到智能家居网络中,通过IPv6实现通信。蓝牙网络和互联网之间的通信通过网关来完成,该网关中包含发起组网的蓝牙根节点并支持IPv4和IPv6协议的转换。实验结果表明,该蓝牙网络在丢包率、组网延时、鲁棒性方面较传统蓝牙网络有明显优势,当网络拓扑结构发生变化的时候,能快速进行应对。The process of traditional Bluetooth networking is cumbersome,and it cannot be well applied in the smart home network.For resolving this problem,a kind of technology based on routing protocol for LLN in Bluetooth networking was proposed.The RPL-based Bluetooth networking was applied to the smart home network,and the Bluetooth devices communicated through IPv6.The communication between the Bluetooth network and the Internet was accomplished through a gateway,which comprised a Bluetooth root node initiating a network and supporting the conversion between the IPv4 and IPv6 protocols.The results of experiment show that the RPL-based Bluetooth network has obvious advantages in terms of packet loss rate,network delay and robustness,and it can quickly respond to the changes of the network topology.
