Abstract: With the rapid development of wireless networking technologies, higher requirements have been placed on power consumption, transmission delay, and reliability in wireless networks.In low-power Bluetooth mesh networks, the use of traditional flooding routing and the Ad Hoc On-Demand Distance Vector(AODV) routing protocol results in redundant packet forwarding, high network power consumption, unstable links, and large communication delays. Therefore, based on the energy-limited AODV algorithm and the Energy-aware AODV (E-AODV) routing algorithm, a Dynamic-Weight ADOV routing algorithm(DW-AODV) is proposed. Based on hop count, residual node energy, and link quality metrics, the node evaluation weights are dynamically adjusted. The communication coverage threshold and the computing capacity of edge nodes are also considered. These factors are jointly evaluated to select the optimal forwarding node. Simulation results show that the improved DW-AODV algorithm can further reduce the number of redundant data packet forwarding in the bluetooth mesh wireless network, and ensure the energy balance of the overall network nodes. Compared with the traditional flooding, the AODV algorithms, and E-AODV algorithm, the proposed algorithm effectively reduces packet transmission delay, network energy consumption, and packet loss rate, thereby improving overall network performance.
