The integration of the Internet of Things (IoT) with next-generation wireless systems, including 5G, 6G, and beyond, is a rapidly evolving research area aimed at enabling ultra-reliable, low-latency, and high-capacity connectivity for massive IoT deployments. Research papers in this domain focus on designing communication protocols, network architectures, and resource allocation strategies that support diverse IoT applications such as smart cities, autonomous vehicles, industrial automation, and remote healthcare. Key contributions include edge/fog-assisted computing, network slicing, AI-driven network optimization, energy-efficient protocols, and security frameworks tailored for heterogeneous IoT devices. Recent studies also investigate the integration of non-terrestrial networks (satellites, UAVs), mmWave communications, and massive MIMO to enhance coverage and reliability. By addressing challenges of scalability, interoperability, QoS, and cybersecurity, IoT research with next-generation wireless systems is driving the development of resilient, intelligent, and future-ready connected ecosystems.
