Design of structural routing optimization of Bluetooth mesh networks for multiscenario applications in distributed smart grid

Due to the characteristic of low-power, the bluetooth mesh network has a great potential in distributed smart grids due to their low-powers. However, due to duplicate forwarding brought on by data broadcasting, traditional routing protocols based on flooding algorithms increase energy consumption. It is obviously unsustainable for battery-powered mesh networks relying on battery power that handlea large amount of data. Therefore, this study designs a novel routing protocol for multi-node, multi-level tree network topology for the specific needs of battery-powered device-dependent nodes in distributed smart grids for multiple application scenarios such as environmental monitoring. The routing protocol is designed by abstracting and analyzing the wireless self-organizing network topology in different scenarios and optimizing the design based on this topological abstraction. Simulation results show that the proposed protocol reduces the energy consumption of sensor nodes by 52.8% compared to the traditional Bluetooth Mesh, and improves the communication reliability at the same time. This improvement provides a new technical path for the wide deployment of Bluetooth Mesh networks in battery-powered smart grid applications.
