Talk 1:

Speaker: Dr George Oikonomou (Communications Systems & Networks (CSN) Research Group)

Title: “IPv6 multicast forwarding in networks of severely-constrained wireless embedded devices”

Biography:

Lecturer in IoT Networking, with 7 years of post-doctoral research experience in the UK (University of Bristol and Loughborough University). Originally a statistician, with an MSc in Information Systems and PhD in Computer Networking from the Department of Informatics at the Athens University of Economics and Business.

Co-founder, steering group member and maintainer of Contiki-NG, the next generation, open source operating system for the IoT. Maintainer of the original Contiki OS. Inventor of the Sensniff open source software project. cc2538-bsl collaborator.

IoT Enthusiast, Software Developer, Open Source & Creative Commons proponent.

My research focuses on energy-efficient networking for severely constrained wireless embedded devices and the IoT, with an emphasis on digital healthcare and smart city applications. My objective is to invent and prototype networking algorithms that are optimised for constrained/low-capability, battery-powered devices without sacrificing performance and reliability. Over the last few years I have been focussing on IEEE 802.15.4 / .15.4g networks, doing work that covers the entire 6LoWPAN/RPL stack. More specifically, I have made contributions in the areas of multicast forwarding; MAC layers with time-synchronisation (such as TSCH); congestion control; routing; neighbour discovery; service discovery. Within the following areas:

My research focuses on energy-efficient networking for severely constrained wireless embedded devices and the IoT, with an emphasis on digital healthcare and smart city applications. My objective is to invent and prototype networking algorithms that are optimised for constrained/low-capability, battery-powered devices without sacrificing performance and reliability. Over the last few years I have been focussing on IEEE 802.15.4 / .15.4g networks, doing work that covers the entire 6LoWPAN/RPL stack. More specifically, I have made contributions in the areas of multicast forwarding; MAC layers with time-synchronisation (such as TSCH); congestion control; routing; neighbour discovery; service discovery. Within the same IoT context, I am also interested in secure software writing techniques; digital forensics; and software defined networking.

My research is very applied and often leads to high-TRL, deployment-ready outputs. A lot of my work has been released as open source software and is distributed as part of the Contiki-NG operating system for the Internet of Things, an open-source project of which I am a co-founder and steering group member. Most of the work is also part of the original Contiki OS, for which I used to serve as maintainer.

Key Contributions to Research Projects

I am Co-I in SPHERE Next Steps, an EPSRC IRC on the development of sensors for the home to diagnose and help manage health and wellbeing conditions. The technology aims to aid early diagnosis, lifestyle change and the ability of patients to live at home. I am leading two work packages, including the one entitled "Design, Integration and Monitoring"; my team and I have delivered the overall architecture of the SPHERE system that is currently being deployed and tested in 100 participant properties in and around the Bristol area. I have also made a key contribution to the hardware and software/firmware design of SPHERE's in-house-developed wearable device, environmental sensor and low-power gateway.

Previously, I was Co-I for RERUM (FP7/2007-2013 grant n° 609094) on the design and implementation of a security framework for the IoT, driven by the requirements of Smart City applications. In addition to research papers and other outputs, I made a key contribution to the hardware and software/firmware design of a novel IoT hardware platform, which is now commercially available.

I was also affiliated with the (now concluded) ForToo project, an ISEC 2010 action grant on the development of advanced forensic tools against Internet abuse, with focus on forensic analysis of android devices and wireless sensors.

I am a member of the CSN and DHE research groups and I am affiliated with Crypto. I am also a member of the Smart Internet Lab
