This Topical Collection is dedicated to highlighting the cutting-edge methods and latest research in the field of smart sensing, primarily in terms of exploring the latest machine learning analytics to extract information from the consequent sensory data, and investigating potential risk and countermeasures to ensure the security and privacy of sensing devices in WSN based Internet of Things/ Industrial Internet of things (IoT/IIoT). It allows researchers in WSN and IoT community to demonstrate their new ideas which may potentially reshape the future of IoT/IIoT. While sensing data have been traditionally processed within a powerful remote cloud server, the recent emergence of edge computing with these communication technologies makes it feasible to perform AI processing at the edges. Edge processing is aimed at overcoming the slower and more expensive method of sending the data to the cloud. The benefits of the parallel development of cloud-edge technologies in wireless sensor networks and communications are manifold. The progress in the development of these technologies has opened several new opportunities in multi-domain applications, such as smart cities, transportation, intelligent manufacturing, and e-Health.

This Topical Collection is dedicated to highlighting the application of Machine Learning (ML), Artificial Intelligence (AI) and Deep Learning (DL) in the field of Microwave Engineering: Devices and Communication. It will concentrate on AI/ML/DL approaches in Microwave Engineering, which includes new breakthroughs, design and performance techniques of various Microwave Devices like Antennas, Filters, Couplers etc. Starting with single/multiband antennas, this topical collection will showcase the application of AI/ML/DL in the design and/or performance features of wideband to super wideband antennas including Multiple-Input-Multiple-Output (MIMO) antenna structures suited for wireless communication.

It will also focus on the use of AI/ML/DL in various aspects of Terrestrial and/or Satellite-based Microwave Communication: Processes, Algorithms and Protocols.
