14 Jan 2020 Seminar: Low Power Wide Area Networks for the Industrial Internet of Things
Speaker: Dr Dimitrios Zorbas
Current Industrial Internet of Things (IIoT) protocols suffer from short
range links and limited mobility. A Low Power Wide Area Network (LPWAN)
solution such as the LoRaWAN can resolve those issues, however, the
ALOHA-based 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.
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.

18 Nov 2019 Seminar: Harmonic Radar to Chase Insects, Massive MIMO & other Research Highlights
Speaker: Dr George Woodward
Title of talk: Harmonic Radar to Chase Insects, Masive MIMO and other Research Highlights from the Wireless Research Centre, University of Cantebury, NZ
The Wireless Research Centre (WRC) at the University of Canterbury, New Zealand, is an industry facing research centre focussing on research challenges defined by the needs of industry and government. The centre has extensive knowledge and experience working with emerging wireless standards, including the 3GPP family of cellular standards (3G, 4G, 5G, and now emerging 6G concepts), local area and personal-area networks. Specific technologies of expertise include information theory, multi-antenna systems (MIMO), modulation and coding, diversity systems, relaying, scheduling, combinations of wireless and geospatial technologies, and the internet of things. Application areas include mission critical communications (civilian and strategic), intelligent transportation systems (vehicular automation), swarm intelligence (e.g. Unmanned Aerial Vehicle/drone swarming), biosecurity (e.g. trapping and tracking of invasive species), and Antarctic operations (e.g. remote sensing).
This talk will introduce the capabilities of the Centre and give some research highlights from the most recent year. We will spend some time talking about an ambitious project to use bistatic harmonic radar operating from a swarm of unmanned aerial vehicles to track insects. The engineering challenges arising from the project are many-fold, including design of miniaturised passive harmonic radar tags for mounting on insects, bistatic radar system design including node synchronisation, and co-ordination of the drone swarm.
Dr Graeme Woodward received B.Sc., B.E., and Ph.D. degrees from the University of Sydney, and has enjoyed a career spanning industry and academia. His extensive industrial research experience includes pioneering VLSI designs for multi-antenna 3G Packet Access (HSDPA) with Bell Labs (Lucent Technologies), Sydney. Subsequently he worked with Agere Systems and LSI Logic with a focus on low power chip design for 3G and 4G (LTE) terminals contributing to chip designs shipped in volume to a major international handset vendor. From 2007 he worked as Research Manager of the Telecommunications Research Laboratory, Toshiba Research Europe (Bristol, UK) engaged in numerous large UK and EU projects. He is now Research Leader with the Wireless Research Centre, University of Canterbury, New Zealand. His speciality is digital baseband signal processing for wireless communications standards, with a particular interest in multi-antenna processing and interference/channel distortion mitigation. He is a Senior Member of the IEEE, has authored more than 50 papers and 12 U.S. patents and has served on numerous conference committees.

14 Feb 2018 Seminar: Photonics for Disaggregated DataCentre and Computercom Architectures
The Smart Internet Lab invites you to join visiting Dr Nikos Pleros from Aristotle University of Thessaloniki, Greece as he shares his insights around how photonics can bring significant functional benefits in computing architectures.
Abstract: How should someone exploit photonics in computing? Simply replacing the electrical with optical wires and increasing the data rate is the first and obvious answer, but the idiosyncrasy of photons can lead to improved architectures that can offer additional functionality in Datacom and Computercom environments.
This talk will concentrate on how photonics can bring significant functional benefits in computing architectures, spanning from disaggregated rack-scale through disintegrated chip-scale and even to the emerging neuromorphic platforms. Nikos Pleros will present how innovative optical switching, photonic Network-on-Chip and optical RAMs can shape a radically new computing environment with increased granularity, modularity, performance and energy efficiency.
