摘要：
蓝牙低功耗（BLE）Mesh被广泛认为是物联网应用的驱动技术。然而，BLE Mesh中缺乏服务质量（QoS），这体现在数据包优先级划分上，极大地限制了其潜力。本研究为BLE Mesh实现了一种QoS方法，根据分配的优先级对数据包进行优先排序，并为其提供不同的网络传输设置。与现有的BLE Mesh QoS研究不同，我们提出的方法无需对BLE Mesh协议进行任何修改，即可在现有BLE Mesh网络中平滑采用。我们开展了广泛的测量活动来评估我们的解决方案，在一个部署用于模拟智能医疗场景的15节点BLE Mesh网络中，45个具有指定优先级的传感器通过网络传输信息。实验提供了单通道和多通道网络场景的性能结果。获得的结果验证了我们的解决方案，展示了已建立优先级之间的差异，并为在BLE Mesh和基于广播的网络上进一步开展QoS研究提供了见解和指导方针。
英文摘要：
Bluetooth Low Energy (BLE) Mesh is widely recognized as a driver technology for IoT applications. However, the lack of quality of service (QoS) in BLE Mesh, represented by packet prioritization, significantly limits its potential. This work implements a quality-of-service (QoS) method for BLE Mesh to prioritize the data packets and provide them with different network transmission settings according to their assigned priority. Unlike existing works on QoS for BLE Mesh, our proposed approach does not require any modifications to the BLE Mesh protocol and can be smoothly adopted in existing BLE Mesh networks. We conducted an extensive measurement campaign to evaluate our solution over a 15-node BLE Mesh network deployed to emulate a smart healthcare scenario where 45 sensors with an assigned priority transmit information over the network. The experiments provide performance results for single and multi channel network scenarios. The obtained results validate our solution, showing the difference between the established priorities and providing insights and guidelines to conduct further research on QoS over BLE Mesh and broadcast-based networks.
