  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.
