This Topical Collection aims to explore the intersection of mathematical modeling, sustainable development, and the challenges and solutions. Rapid technological advancements and the increasing need for sustainability have created complex problems that require innovative mathematical modeling approaches to address them. This Topical Collection welcomes high-quality research papers that demonstrate the application of mathematical modeling in various domains, including but not limited to finance and economics, data science and machine learning, artificial intelligence, cyber security, Internet of Things (IoT)‎, cryptography and information security, and biomathematics. The goal is to showcase how mathematical modeling can contribute to sustainable development by providing insights, decision support, and optimization strategies for complex systems in science and information technology.

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.
