Priority-Aware Spectrum Allocation for IoMT-URLLC: A Review of DRL Modeling, Metrics, and PPO/SAC Selection
Internet of Medical Things (IoMT) systems supporting remote surgery, ward monitoring, emergency alert systems, and wearable sensors increasingly rely on ultra-reliable low-latency communication (URLLC) transmission. This targeted review systematically summarizes existing research on deep reinforcement learning (DRL)-ba...
