D3 seminar on Low Power Wide Area Networks for the Industrial Internet of Things

17 October 2019 @ 14:00 pm - 15:00 pm

The talk will be given by Dr. Dimitrios Zorbas from Tyndall National Institute.

Current Industrial Internet of Things (IIoT) protocols suffer from short range links and sometimes long delay due to the multi-hop nature of their topologies. A Low Power Wide Area Network (LPWAN) solution such as the LoRaWAN can resolve those issues, however, the ALOHA-style transmission policy of those technologies makes the delivery of a large number of packets by a large number of nodes impossible . To avoid bursts of collisions and expedite data collection, we propose scheduling of transmissions in time slots. We provide evidence through extensive experiments that time-slotted synchronous LPWAN communications are feasible under different node arrangements. Apart from that, more and more industrial applications require battery-free solutions that last for ever. To tackle this issue, energy harvesting techniques such as the wireless power transfer have been proposed to power-up energy constrained IoT devices. During the presentation a number of ideas will be given to achieve the battery-free goal in a dynamic and mobile industrial environment.



Dr. Dimitrios Zorbas holds a PhD in Computer Science from the University of Piraeus in Greece. He has worked as a post doctoral researcher at Inria Lille – Nord Europe and at University of La Rochelle in France. He is currently researcher at Tyndall National Institute after receiving a Marie Curie fellowship. He is author of more than 40 peer-reviewed publications in the area of computer communications, energy efficiency in networks, and secure communications. He has also worked in several national as well as FP7 and H2020 projects. He is member of the IEEE.
