摘要
Abstract
To address issues of packet redundancy and high energy consumption associated with the managed flooding routing mechanism used in the Bluetooth Low Energy(BLE)Mesh network specifications,an energy-efficient routing algorithm for dynamic BLE Mesh network is proposed.By establishing a Q-Learning based routing model for BLE Mesh network,this algorithm incorporates factors such as residual energy of nodes,forwarding costs,mobility factors,and Received Signal Strength Indicator(RSSI)into the design of the reward function.Improvements to the heartbeat mechanism in the BLE Mesh network enable nodes to more effectively gather environ-mental information.An exploration-based routing discovery mechanism is utilized to update the Q-values of the nodes within the net-work,thereby more accurately reflecting changes in network topology caused by node movements.Simulation results demonstrate that this algorithm outperforms traditional managed flooding routing mechanism in terms of node energy consumption and overall network over-head.关键词
