Abstract: Connectivity, in particular wireless connectivity, is a key enabling technology for the Internet of Things. A plethora of technologies exist ranging from short range to long range and low to medium power options. Recently, long range, low power wireless communication technologies have been introduced, for both licensed and unlicensed radio spectrum. Unlicensed spectrum technologies such as LoRa/LoRaWAN have become very popular because of their low cost, open standard and open source software support. However, the current standard has many weaknesses in supporting a vision of dense, wireless IoT device deployment. In this talk we will briefly review long range, low power wireless technologies, review some of the weaknesses of LoRa/LoRaWAN and present a range of advances that address these weaknesses, in particular we will focus on medium access fairness, power efficiency and delay performance for both terrestrial and satellite based IoT applications.

Bio: Dr. Dirk Pesch is a Professor of Computer Science in the School of Computer Science and IT at the University College Cork, Ireland where he leads research initiatives in the area of future networks, Internet of Things (IoT) and Cyber-Physical Systems (CPS) with applications to smart and connected communities, energy efficient buildings and sustainable cities, and smart manufacturing. In these areas, his own research interests focus on the study, design and performance evaluation of IoT and CPS and associated communication protocols, system architectures, and their interoperability. Dr. Pesch is the Director of a national doctoral school, the Science Foundation Ireland (SFI) funded Centre for Research Training in Advanced Networks for Sustainable Societies. He is also a Principal Investigator of the SFI funded CONNECT Centre for Future Networks and the CONFIRM Centre for Smart Manufacturing, is an editorial board member of Springer Wireless Networks and MDPI Sensors. He also contributes to international conference organization in his area of expertise including the IEEE World Forum on the Internet of Things, IEEE VTC, IEEE Globecom, IEEE ICC, IEEE WCNC, IEEE WoWMoM, IFIP Networking and other conference and workshops. Prior to joining academia, Dr. Pesch was a design engineer with Nokia in Germany and the UK, developing and implementing communication protocols for a range of cordless telecommunication products. He received a Dipl.Ing. degree from RWTH Aachen University, Germany, and a PhD from the University of Strathclyde, Glasgow, Scotland, both in Electrical and Electronic Engineering.
