The development of Industrial Internet of Things (IIoT) has been limited due to the shortage
of spectrum resources. Based on cognitive radio, the cognitive IIoT (CIIoT) has been …

The cognitive industrial Internet of Things (CIIoT) can improve transmission performance by
utilizing the spectrum licensed to a primary user (PU), providing that the normal …

Sixth generation (6G)-enabled Internet of Things (IoT) needs sufficient spectrum resources
to provide spectrum access for massive IoT's terminals. However, traditional orthogonal …

In this work, an uplink secondary Internet of Things (IoT) device scheduling and power
allocation problem based on imperfect channel state information (CSI) and imperfect …

In a conventional cognitive radio (CR) network, only when the primary user's (PU) frequency
bands are sensed to be free, secondary users (SUs) can utilize these frequency band …

In traditional cognitive radio (CR), secondary user (SU) can only access the idle spectrum
when primary user (PU) is absent, which has to vacate the spectrum when detecting the …

Fog computing, as a promising technique, is with huge advantages in dealing with large
amounts of data and information with low latency and high security. We introduce a …

The proliferation of the Internet of Things (IoT) demands a diverse and wide range of
requirements in terms of latency, reliability, energy efficiency, etc. Future IoT systems must …

The Internet of Things (IoT) that allows connectivity of network devices embedded with
sensors undergoes severe data exchange interference as the unlicensed spectrum band …

Cognitive industrial Internet of Things (CIIoT) can extend available spectrum resources by
accessing the spectrum licensed to primary user (PU) on the premise of not disturbing the …
