Aiming to address the issue of channel competition in hybrid networks of PLC and WC, this study proposes a MAC access algorithm based on deep reinforcement learning for dual-mode communication over power lines and wireless channels. Dual-mode nodes adaptively access the dual-medium channel based on data such as network broadcast information and channel usage. First, a dual-mode node data collection model is established based on interactions and statistical information from dual-mode communication networks. Then, the DRL state space, action space, and rewards are defined based on collaborative information, and an adaptive access algorithm is developed using a dual deep Q-network. This algorithm incorporates a node decision-making process that combines the α-fairness utility function with the P-persistent access mechanism. Finally, simulations and comparative analyses of the algorithm’s performance are performed. Simulation results show that the proposed access algorithm effectively improves the access performance of dual-mode communication nodes while ensuring fairness in dual-mode network and channel access.
