Title: On the shoulders of Tesla: Efficient Algorithms for Wireless Power Transfer in the Internet of Things (IoT)

Abstract: A Wireless Power Transfer (WPT) system consists of chargers which transmit power wirelessly and receivers which harvest the radio frequency energy from the chargers. WPT has evolved to a very active research subject, as well as a topic of rapid technological progress and emerging practical development and commercial applications. However, a solid foundational and algorithmic framework seems still necessary for WPT to achieve its full potential.

In this respect, the talk aims to discuss different characteristic abstract WPT models (scalar, vector, peer to peer) and present key optimization problems (power maximization, coverage, placement, radiation control). Relevant algorithmic design and analysis methods and performance properties (and their trade-offs) are also provided, as well as interesting WPT notions and concepts (such as super-additive and cancellation phenomena in the received power, notions of electromagnetic radiation control in dense, strong WPT fields and energy-aware distributed network formation in large populations of very weak mobile nodes).

Title: The Cognitive Edge

Abstract: The quasi-exponential growth rate in deployment of edge devices naturally leads to an equivalent growth requirement for communication bandwidth. Making the edge nodes more intelligent themselves could counter this need, and lead to a more “cognitive” edge. This would come with other benefits such as improved response time, robustness, privacy, and security. However, realizing a truly cognitive edge pushes the state-of-the-art in AI, requiring true plasticity, fast on-line and incremental learning and quick adaptation to circumstances and environment, all of this at a fraction of the energy footprint of today’s machine-learning implementations. In this presentation, we will argue how a joint exploitation of innovation in computational paradigms, architecture and technology could lead to a 100x reduction in energy consumption for smart nodes at the edge.

Title: Aspects of Time and Space in Wireless Connectivity beyond 5G and 6G

Abstract: Wireless connectivity augments human capabilities beyond their natural domain, enabling operation and interaction with objects and subjects placed within an extended space-time domain. This talk will highlight aspects of time and space as these two basic physical notions get intertwined with the digital wireless communication systems beyond-5G/6G. In terms of time, the talk will present the general concept of timing in wireless communication systems and networks and its relation to effective information generation, processing, transmission, and reconstruction at the senders and receivers. Starting from the focus on latency, a specific instance of timing being in the focus of 5G, the talk will present a statistical framework of timing requirements in wireless systems. The timing framework subsumes both latency and Age of Information (AoI) and applied to various communication models, such as consensus or distributed learning/inference. In terms of space, wireless environments evolve towards becoming intelligent and reconfigurable. The talk will discuss the communication modeling aspects of reconfigurable wireless environments. Finally, leveraging the ambiguity of the term “space”, the talk will provide a perspective on non-terrestrial/satellite networks and their role in future wireless connectivity.

Title: A DOA based framework for IoT security and interoperability

Abstract: Traditional IoT applications generally take an application-centric approach, where management and access of IoT devices are confined within each IoT applications. Over time, this presents a barrier for IoT interoperability and produces many information silos.
Digital Object Architecture (DOA) provides an infrastructure solution for IoT interoperability. The DOA based IoT framework, as described in ITU-T standard Y.4459, will help free information from IoT application boundaries and allow information to be shared freely and securely across all kinds of IoT applications. It also allows discretionary security to be defined and managed per IoT device, instead of subjective to each IoT application.
The DOA based IoT framework defines a IoT device-centric approach that allows separation of the storage, ownership, and management of the IoT devices from individual applications, yet allows each and every application to access such information in a secure and trusted fashion. Information security is no more in the hands of the security measure of, or lack of, any particular application, but in the hands of the owner/manager of IoT device.
