面向变电站场景的蓝牙Mesh网络结构化路由协议

Research on Structured Routing Protocol of Bluetooth Mesh Networks for Substation Scene

针对变电站场景下微功耗传感器具有部署范围广、采样频率低、单次发送数据量大等技术特点,提出了多父亲节点多层次树网络拓扑,用于对变电站场景下的无线自组织网络拓扑的抽象,并基于拓扑抽象,设计了一种结构化路由协议。实验和仿真结果表明,与标准蓝牙Mesh及Lora通信相比较,功耗、通信可靠度等优势明显,使用提出的结构化路由协议的传感器功耗相较于标准蓝牙Mesh的功耗降低了83.3%。

In view of the technical features of micro-power sensors in the substation scene with wide deployment range,low sampling frequency,large amount of data sent in a single time,etc.,this paper proposes a multi-parent node multi-level tree network topology for abstracting the wireless Ad Hoc network topology in the substation scene.Based on topological abstraction,this paper designs a structured routing protocol.Experimental and simulation results indicate that the power consumption and communication reliability of this scheme are significantly superior compared to standard Bluetooth Mesh and Lora communication,and the power consumption of the sensors using the proposed structured routing protocol is reduced by 83.3%compared to that of standard Bluetooth Mesh.
