Title: Big Sensed Data challenges in the Internet of Things

Speaker: Prof. Hossam S. Hassanein ()
  • School of Computing
    Queen's University
    Kingston, ON, Canada

  • Internet of Things (IoT) systems are inherently built on data gathered from heterogeneous sources. In the quest to gather more data for better analytics, many IoT systems are instigating significant challenges. First, the sheer volume and velocity of data generated by IoT systems are burdening our networking infrastructure, especially at the edge. The mobility and intermittent connectivity of edge IoT nodes are further hampering real-time access and reporting of IoT data. As we attempt to synergize IoT systems to leverage resource discovery and remedy some of these challenges, the rising challenges of Quality of Information (QoI) and Quality of Resource (QoR) calibration, render many IoT interoperability attempts far-fetched. We survey a number of challenges in realizing IoT interoperability, and advocate for a uniform view of data management in IoT systems. We delve into three planes that encompass Big Sensed Data (BSD) research directions, presenting a building block for future research efforts in IoT data management.

Title: Fundamental Concepts, Models, Problems and Algorithms for Wireless Power Transfer in Adhoc Communication Networks

Speaker: Prof. Sotiris Nikoletseas
  • Department of Computer Engineering and Informatics
    University of Patras and CTI
    Patras, Greece

  • 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).
