In this seminar, a report will be made on the research activity carried out in two Seed projects of Wireless@KTH that pertain the monitoring by the LTE infrastructure of two vital systems in the smart cities: Smart Grids, and Water Distribution Networks.
The Smart Grids, or the electrical distribution of power to the end-users, allow advanced monitoring and remote control services thanks to bi-direction communications between energy producers and consumers. Extending energy automation introduces the need for timely and reliable information exchange over wide areas. The use of LTE infrastructure appears as a promising solution, since LTE supports extensive coverage, low latency, high throughput and Quality of- Service (QoS) differentiation. In this project, an integration of LTE with the smart grids communication automation standard IEC 61850 is carried out, and a new LTE QoS class is introduced along with a new LTE scheduler that prioritizes smart grids traffic. Two representative automation services are considered, a centralized (MMS) and a distributed one (GOOSE), and the achievable latency/throughput performance is evaluated in a radio system simulator platform. Simulations of realistic overload scenarios demonstrate that properly designed LTE schedulers can successfully meet the performance requirements of IEC61850 services with negligible impact on background traffic.
In water Distribution Networks, we have studied the integration of wireless sensor networks, device-to-device (D2D) and LTE wireless communications for pollution detection in the urban water pipelines. The main network structure is based on emerging D2D communications. The key challenges are efficiently integrating wireless sensor networks (the devices) with cellular network infrastructure. The network design has addressed the new problems in, e.g., infrequent and irregular traffic, difficult wireless communications, low mobility, small battery, large number of devices, device damage, and hierarchical network architectures. We have shown that the transmission scheduling can be optimized by energy-balancing solutions, so that a maximum lifetime of the sensor network infrastructure is achieved.
Bio: Dr. Carlo Fischione is currently a tenured Associate Professor at KTH Royal Institute of Technology, Electrical Engineering and ACCESS Linnaeus Center, Stockholm, Sweden. He received the Ph.D. degree in Electrical and Information Engineering (3/3 years) in May 2005 from University of L’Aquila, Italy, and the Laurea degree in Electronic Engineering (Laurea, Summa cum Laude, 5/5 years) in April 2001 from the same University. He has held research positions at Massachusetts Institute of Technology, Cambridge, MA (2015, Visiting Professor); Harvard University, Cambridge, MA (2015, Associate); University of California at Berkeley, CA (2004-2005, Visiting Scholar, and 2007-2008, Research Associate); and Royal Institute of Technology, Stockholm, Sweden (2005-2007, Research Associate). His research interests include optimization with applications to wireless sensor networks, networked control systems, wireless networks, security and privacy. He has co-authored over 100 publications, including a book, book chapters, international journals and conferences, and international patents.
