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.

The agri-food sector is under pressure to move towards more efficient, sustainable and environmentally friendly production systems capable of providing affordable, safe and high-quality food to a growing world population facing climate change and resource scarcity, but also pandemics and conflicts. Therefore, research and innovation on future-proof food production systems, including vertical and urban farming and more efficient post-harvest and processing technologies, is crucial for greater competitiveness and resilience. This topical collection aims to bring together recent advances and new concepts on sustainable food production, processing, and manufacturing, as well as on the upcycling of agri-food waste and by-products into bioactive functional ingredients in line with circular economy principles. Cutting-edge research on novel techniques for food quality assessment, authentication, and traceability is also covered in this transdisciplinary topical collection.
