Short Bio & Research

I am currently a Lecturer in AI for Digital Infrastructures with the University of Bristol and a member of Bristol Digital Futures Institute (BDFI) and Smart Internet Lab. I holds an MSc degree in Parallel and Distributed Computer Systems from VU Amsterdam and the PhD degree in informatics from AUEB Athens. My current research focus is on natively-inteligent 6G architectures aiming Zero-touch networking, end-to-end, from Core to the Edge/RAN. In the past, I have worked on 5G and Information Centric Networking novel architecture designs and protocols.

Projects in a nutshell: My experience includes participation in seven EU funded international projects (including the FIA award-winning FP7-PURSUIT), one industry-funded, one Greek national project, and one French grant-funded project, all on topics related to 5G/6G and distributed systems and network architectures.

Currently running projects:

DCMS REASON - since 1/3/2023
EPSRC TITAN (Platform Driving The Ultimate Connectivity) - since 1/4/2023
H2020 5GASP - since 1/1/2021

EPMS-Sim (2013-2017): EPMS-Sim stands for Efficient Proactive Mobility-based Support models Simulator. It is a software package that contains the latest version of a long-lasting PhD and postdoc work from 2013 until early 2017, which is related to publications on efficient proactive mobile caching and proactive mobile multicast solutions. The latest version of the code can be found in a corresponding version-indicated branch (not under the master branch) on my account on GitHub. For understanding the models provided in the software, please refer to:

Blacksabbath (2011-2012): multicast chat over Blackadder, called Blacksabbath in honor of (what I believe to be) the most important band in the history of rock music, is a simple, server-less, fully distributed chat application that demonstrates the multicast capabilities of Blackadder. Blacksabbath operates on top of Blackadder; therefore, a working installation of Blackadder is assumed. Moreover, Blacksabbath uses the "independent Java binding" that comes with Blackadder. Please consult Blackadder instructions on compiling and building the Java binding. Necessary libraries are located in the "lib" sub-directory, but the native Java binding to Blackadder must be provided by the user (see Execution).

jDONA (2012): JDONA is a free, custom Java version simulator of the basic Data Oriented Network Architecture (DONA) functionality. It is designed to emulate in a fully parallelised fashion the essential functionality for simulating FIND and REGISTER requests in order for the emulations to scale over a CAIDA realistic (full) size inter-domain topology. Source files are provided along with a detailed installation guide given in README.txt. You may freely extend, alter and redistribute Donalight under the GNU licence that comes with the package.

Donalite (2011-2012): The package contains a patch for OverSim-20090908 source files along with a detailed installation guide given in README.txt. You may freely extend, alter and redistribute Donalight under the GNU licence that comes with the package.

Greek NERC (2007): This compressed file contains the software of the Greek Named-Entity Recognizer that was developed in the final-year undergraduate project described in the following report (in Greek): Xenofon Vasilakos, "Named entity recognition and categorization in Greek texts with Support Vector Machines", Department of Informatics, Athens University of Economics and Business, 2006. The system is also described in the following paper (in English): G. Lucarelli, X. Vasilakos and I. Androutsopoulos, "Named entity recognition in Greek texts with an ensemble of SVMs and active learing".
