he Telecommunications Software
& Systems Group (TSSG) were
delighted to announce the
enormous achievement of Dr.
Raymond Carroll, who, in November 2011,
successfully defended his PhD dissertation.
The external examiner, Professor Junichi
Suzuki from the University of Massachusetts,
Boston, was very complementary about
the breath, novelty and potential of Ray’s
work which was on bio-inspired service
We met Ray following his successful defence.
Congratulations Ray, you have had to an
immense amount for work to achieve your PhD,
tell us a little about your academic career?
Thanks, I completed my undergraduate degree
which was BSc in Applied Computing in WIT. I
then went onto complete a Masters also in WIT.
I joined TSSG in the summer of 2002 and finally,
I commenced my PhD in November 2008,
as a member of the specialised Bio-Inspired
Research Unit at the TSSG which is managed by
Dr. Sasi Balasubramaniam.
What does the research unit do?
Within the group, the Service Management
research strand investigates biologically inspired
approaches to allow services autonomously
self-govern, with minimal human intervention.
The solution investigated, models each
individual service as a biological entity.
Therefore, similar to a biological organism,
each service is able to migrate, replicate,
manage its own energy, and die. This is similar
to behaviours found in typical biological
organisms, which consume food to maintain
energy while performing work. In the event
that the current habitat becomes harsh, the
organisms would migrate to a new environment
and reproduce or replicate to create new
colonies. Another important facet of biological
organisms is the ability to form communities.
In each community, the organisms are able to
co-exist with other organisms in a symbiosis, by
supporting and collaborating as a group.
The service management approach at the
Bio-Inspired Research Unit at TSSG, embeds
these different mechanisms and behaviours into
the services to allow these service entities live
autonomously in an environment. This enables
the services to be efficiently discovered, in order
to maximize the user’s request. At the same
time, through the concept of communities,
efficient and large scale distributed service
composition can be achieved.
Did you find working in the research unit as part
of your PhD programme an advantage?
Particularly with the way the TSSG PhD
programme is structured I enjoyed a more
intense supervision rather than a single
supervisor and monthly meetings, the TSSG
provides each student with a two-man co-
supervision team, and a minimum of one
meeting every week.
I really enjoyed doing my PhD at TSSG because
I was constantly given guidance from my
supervisors who are leading researchers in Bio-
Inspired Networking, the area I have specialised
in and they were always on hand to assist.
Having a team provides students with easily
accessible advice in every area, from work on
particular aspects of the paper, through generic
training skills, to assistance with the actual
writing of the paper. The TSSG has a strong
emphasis on publishing in good conferences
and journals.
Have you done any lecturing or travel as part of
your PhD?
Yes I have been lecturing on and off for the
last number of years, particularly in the area of
Database Management and Web Design.
I have been lucky enough to have had a
number of great trips. Most recently Japan and
Hawaii, but also Canada, USA, Spain, Portugal,
What was your final dissertation on and what
do you hope to do with your PhD?
My PhD was in the area of “Biologically Inspired
Autonomous Service Management for Future
Internet.” These are internet services that
have additional behaviour that is inspired by
biological processes. For instance services can
choose to migrate to new locations under
certain conditions. I developed a framework
for building these biological services and then
applied this to a number of Future Internet
problems. One such application was in allowing
services to migrate to new data-centres in
order to use more renewable energy and
minimise the use of cooling energy. This was
done by allowing services determine which
data-centres had higher levels of renewable
energy and which data-centres had lower
ambient temperatures. As part of the research
I published in a number of international
conferences (e.g. ICC, Globecom, Bionetics) and
Journals (Computer Networks, International
Journal of Autonomous and Adaptive Systems
My plan is to continue my research in the
area of bio-inspired services at TSSG, looking
towards new problems that can be addressed
and new biological models with which these
might be solved. I’m very excited about future
prospects and the possibilities are endless.
Congratulations also goes to Ray’s supervisors;
Dr. Sasi Balasubramaniam, Research Unit
Manager, Senior Research Fellow, Dr. Dmitri
Botvich, and Dr. Willie Donnelly, Director, TSSG.

APRIL 26-27TH 2012
CSP EU FORUM) Berlin, Germany 2012
TSSG as project lead of Effectsplus are coordinating with the Trust and Security Unit of DG INFSO in organizing the “CSP EU
Forum 2012” (Cyber Security & Privacy EU Forum).
This event is a European conference on Cyber Security and Privacy, to be held at the Science & Conference Center “The
Dahlem Cube”, Seminaris Campus Hotel, Berlin on the 24th and 25th April 2012. The Dahlem Cube is located at the
Campus of the Freie Universiät Berlin.
This year, the CSP EU Forum theme Investigates “Cloud Security and Data Privacy issues” -We will be discussing the
threats, vulnerabilities, enemies, risks and best practices of Cloud Computing for Europe.
