Riya Dinesh Deshpande, Faheem A. Khan, Qasim Zeeshan Ahmed·October 16, 2024
Summary
The paper introduces using Deep Q Network (DQN) for efficient spectrum allocation in vehicular networks, addressing dynamic environment challenges. DQN, a Deep Reinforcement Learning method, enhances spectrum sharing efficiency, demonstrating adaptability in V2X communication. Both SARL and MARL models show successful V2V communication rates, with the RL model's cumulative reward reaching maximum as training progresses. The system model employs a DQN model, integrating RL and DL, to address spectrum sharing challenges. Reinforcement Learning algorithms, like SARL and MARL, are utilized for efficient spectrum management and scalability in vehicular networks.
