Wireless On-demand Network systems and Services Conference
20 - 22 January 2016, Cortina d'Ampezzo, Italy
(Some examples of) Inter-disciplinary Research in a Cyber-Physical Converging World
Cyber-Physical Convergence is a way to define the blurring between the cyber
world (enabled by Internet technologies, services and apps) and the physical
world. Together with advanced Internet services, this trend is nowadays boosted
by the diffusion of personal mobile devices, of miniaturised "things", and the
pervasiveness of wireless networks. Jointly, these elements support a constant
flow of data between the two worlds, which in turn results in actions taken in
either of them, with mutual impact on each other. Examples are, among others,
smart cities, where the cyber world constitutes a "nervous control system" of
the physical city infrastructures, or Online Social Networks, where social
relationships in the physical world impact on the users' behaviour in the cyber
world, while communities formed online generate actions and behaviours in the
physical word (e.g., people gatherings, protests, parties).
In this talk I will motivate why in this perspective inter-disciplinary research
is such an exciting and powerful approach for human-centric networking systems.
I will go through a number of cases where information about the behaviour of
the humans is exploited to design efficient networking and computing systems,
primarily supporting data dissemination between users in mobile self-organising
networks. This goes beyond conventional bio-inspired approaches. Here personal
mobile devices are seen as "proxies" of their users in the cyber world, and
therefore include human behaviour models as core components of their
functionalities. At the level of the individual person, I will discuss how
models of the cognitive process of the brain can be exploited to design
efficient self-organising data dissemination schemes implemented in users'
mobile devices. At the level of the social behaviour, I will show how models of
people's social structures can be exploited to support data dissemination in
Mobile Social Networks. I will also discuss how evolutionary anthropology models
of human social organisations can be used to analyse the social structures in
Online Social Networks, and the patterns of information diffusion at varying
levels of trustworthiness. Finally, I will discuss how the two dimensions
(individual and social) can be blended together to design even more efficient
data dissemination schemes in mobile networks. The talk will conclude by
discussing some perspectives and open issues along these research directions.
About the speaker:
Andrea Passarella (Ph.D 2005) is currently a Researcher at the Institute for
Informatics and Telematics (IIT) of the National Research Council of Italy
(CNR). Prior to join IIT he was with the Computer Laboratory of the University
of Cambridge, UK. His research interest include Online and Mobile social
networks, opportunistic, ad hoc and sensor networks, with special emphasis on
inter-disciplinary aspects. He has published 100+ papers on these topics,
receiving the best paper award at IFIP Networking 2011 and IEEE WoWMoM 2013. He
is co-author of the book "Online Social Networks: Human Cognitive Constraints in
Facebook and Twitter Personal Graphs" (Elsevier, 2015), and was Guest Co-Editor
of several special sections in ACM and Elsevier Journals and of the book
"Multi-hop Ad hoc Networks: From Theory to Reality" (2007). He is the chair of
the IFIP WG 6.3 "Performance of Communication Systems".
Towards the Symbolic Analysis of Networked Systems
The behavior of networked systems is determined by their implementation,
their configuration, and most importantly their interactions: any input
may arrive at any time.
To ensure that networked systems function as intended, a thorough
analysis of their behavior is of upmost importance. Since network
interactions are beyond the influence of the system developer the
implementations of networked systems must be able to handle all
possibilities and uncertainties of network input and input timings.
The difficulty of considering these in all implementations is the
source of most reliability and interoperability issues.
This talk will present the first steps towards a new methodology based
on Symbolic Execution that aims at combining the benefits of model
checking (rigorous exploration) and of dynamic software testing
(analyzing real systems' code) to enable a thorough analysis and
prediction of the behavior of networked systems.
The talk presents KleeNet, the first symbolic analysis tools for network
input and discusses the path towards the analysis of temporal
uncertainty in network interactions.
