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.
