Intelligent Random Access Framework for Massive and Ultra-Reliable Low Latency IoT Communications

The Internet of Things (IoT) enables smart cities to achieve the vision of connecting everything by smartly linking gadgets without the need for human interaction. However, due to the rapid proliferation of IoT devices, the amount of data produced accounts for a significant share of all communication services. Hence, 6G-enabled specifications for wireless networks are required to enable both massive and ultra-reliable low-latency access to such a hybrid IoT network. In this article, we propose a smart hybrid random access (SH-RA) scheme for massive connections and ultra-reliable low-latency access in the network architecture of IoT communications. According to numerical results, compared to the other baseline schemes, the SH-RA framework enormously enhances the total access probability and fulfills the quality-of-service (QoS) requirements.
