ArcLabs Tech Sessions

TSSG recently held the first ArcLabs Tech Session. These Tech Sessions are designed to crowd-source material from a conference and disseminate it amongst those taking part in the session. The recent Google I/O Conference was chosen as the topic for the June event. 16 participants from WIT, TSSG and OSS Software condensed 12 hours of video footage into informal presentations (or talks) lasting less than an hour in total.

In total, the session lasted just 2 hours. This included time required to split participants into groups, select a video from the conference and review and collate notes with others of their group. The ArcLabs Tech Sessions are open to anyone wishing to participate and a Google+ community has been created around them.

The Session was organised by Jerry Horgan from TSSG. The next session is currently being planned for July 2013.

TSSG attends the 1st International Summer School on Nanocommunications

TSSG PhD student, Michael Taynnan Barros attended the 1st International Summer School on Nanocommunications in the Technical University of Tampere, Tampere, Finland, during May 21st-23rd. Mr. Barros is currently performing research in molecular communications, focusing on calcium signaling based nanonetworks.

The event featured the leading experts in the nascent Nanocommunication area, who provided enlightening presentations about the state of art, future trends and possible application domains. More than 20 students and researchers were in Finland with the intention to learn and discuss about Molecular Communications and Nano Netoworks. Prof. Ian Akyildiz, Broadband Wireless Networking Lab with Georgia Institute of Technology, USA, opened the event with a talk about the Internet of Nano Things, where he stated that nanomachines will have a major spot in the future of human development providing infrastructure and services.

Highlights of the second day were the talks from Dr Sasitharan Balasubramanian (Research Fellow, Technical University of Tampere, Finland and a TSSG alumni) and Prof. Craig Forest (Assistant Prof., Georgia Institute of Technology, USA). Both concentrated on bacteria communication networks. Dr Baslasubramaniam showed the current state-of-the-art the multi-hop bacteria communications. He presented a novel routing protocol that uses a biological technique called bacteria conjugation. On the other hand, Prof. Forest presented a methodology to build microfluid devices for empirical analysis of bacteria molecular communications.

Dr Olga Kara (Research Fellow, Technical University of Tampere, Finland) presented, on the last day, an interesting research about communications systems using neuronal cells. The research aims to provide a communication infrastructure for nanomachines using the neuronal cells as a communication channel.

TSSG at 11th International Conference on Formal Concept Analysis

Dr Ruairí de Fréin, a Researcher at the Telecommunications Software & Systems Group (TSSG) attended and presented a paper, “Formal Concept Analysis via Atomic Priming”, at the 11th International Conference on Formal Concept Analysis (ICFCA) which was held in the Dresden Technische Universitat, in Germany on the 21st of May 2013.
ICFCA is the main forum for researchers working on theoretical and applied aspects of Formal Concept Analysis worldwide, Lattice and Order Theory, and has an acceptance rate of 33%; Formal Concept Analysis (FCA) provides a correct and unique solution to data decomposition problems arising in semantic Web, data mining, knowledge representation, management and visualization where a unique decomposition of the dataset is desired.
The main short-coming associated with FCA is its complexity. Dr de Fréin presented recent results which demonstrate how the mining time associated with the formal concept analyses may be reduced by distributing the mining workload over a number of independent computing processes such that no communication between the different processes is required during the separate analyses –this work may lead to considerable time-savings in data analytics. In addition, the uniqueness and lectic order properties of the traditional FCA solution, are preserved by the distributed/networked computing techniques presented by Dr de Fréin, namely Reduced Rank Formal Concept Analysis (RRFCA).
Dr de Fréin is currently a research fellow with the Emerging Networks Laboratory at TSSG.

TSSG PhD student one of five students attending RIPE66 meeting under the RACI programme

TSSG PhD student Runxin Wang recently attended the RIPE66 meeting in Dublin. This conference was hosted by RIPE NCC (Réseaux IP Européens Network Coordination Centre), which is an independent, not-for-profit membership organization that supports the infrastructure of the Internet through technical coordination in its service region. RIPE NCC is one of five Regional Internet Registries providing Internet resource allocations, registration services and coordination activities that support the operation of the Internet globally. The 66th RIPE meeting (RIPE66) in was well supported by many major IT companies and network operators including Google, Amazon, Netflix, and HEAnet. Presentations at the meeting covered the recent developments, experiences, statistics and new ideas about the management of bandwidth usage, IP usage, routing technologies, DNS security and other topics of global networking from different countries. This year RIPE launched a new program RACI (RIPE Academic Cooperation Initiative) to bring in more students from academia to share their research work to the RIPE community; Runxin was one of the five invited students in the RACI program.

TSSG student presents paper at IT&T 2013

TSSG PhD student Runxin Wang recently presented a paper entitled ‘Experimental evaluation of vector bin packing algorithms on VM consolidations in cloud data centres’, at the 12th Information Technology & Telecommunications (IT&T) conference in Athlone, Ireland. The paper is written by John Furlong, Dr Lei Shi and Runxin Wang; it describes a set of performance evaluations carried out on Virtual Machine (VM) consolidation algorithms used to manage virtual computing resources in cloud computing data centers. When formalizing the problem, VM consolidations can be represented as a bin packing problem, as the application of virtualization technology and live migration allow a large number of VMs, treated as items, to be migrated and concurrently hosted into relatively fewer number of Physical Machines (PMs), treated as bins, as long as the sum capacity of the co-located VMs does not exceed the capacity of a hosting PM. This paper aims to find out which bin packing strategies result in minimal numbers of PMs used to host the given VMs and minimal numbers of migration requested to realize the consolidation.

The IT&T conference in this year was sponsored by Ericsson, the proceedings are comprised of research papers and posters from both academia and industry, providing a good opportunity for the practitioners to discuss their early ideas and results.
