ICON (DTN-Amazon project), 2012

ICON - Information and Context Oriented Networking



Nelson Morais, Bruno Batista and Paulo Mendes, ICON - Information-centric Opportunistic Networking, SITI-SW-12-06, 201.


ICON is an implementation of an information and Context Oriented Networking framework. ICON is being developed primaly for opportunistic networks (e.g. Delay Tolerant Networks), but can be used in more stable mobile networks and even in the Internet.


The basic data centric communication functionality is based on prior work from CCN/NDN - forwarding and interest structures, and HAGGLE - flexiblility required to operate in opportunistic networks.


The ICON architecture includes three main entities:

  • a data engine, which takes care of adequately storing/wrapping previously collected data for treatment by the other ICON entities (e.g. what data to store and for how long). Thais entity is based on the CCN concepts for PIT, FIB, and Content Stores.
  • a networking engine, which manages all of the networking interfaces and protocols .
  • decision engine has a set of advanced functionality such as a declarative rule management, behaviour infer both towards the application layer and the networking layers, social awareness, context collector and synchronized in-network caching.


ICON main features are:

  • An open-source, modular platform for information-centric technology, which can easily be extended by adding new modules (e.g. a routing module).
  • An xml-based interface to obtain collected data.
  • Capability to interoperate with any information-centric routing protocol





ICON has been developed to be agnostic to the Operating System, and is currently developed for Android.

The prototype is expected to be ready in September 2012 to: Windows, Lunux, MACOs, as well as on embedded platforms, based on .NET.



The Team

ICON is a tool developed in the context of the DTN-Amazon project, by SITILabs, Universidade Lusófona.


The core team of ICON is:

Paulo Mendes, conceptual supervisor and DTN-Amazon scientific coordinator (SITILabs Scientific Director for Innovation)

Bruno Batista, daily supervisor (SITILabs researcher and PhD student at MAP-i Doctoral Programme).

Nelson Morais, MSc student at Universidade Lusófona/SITILabs and  responsible for the implementation of ICON.





The slides and poster presented at the CCNxCon 2012 workshop, hold at Sophia Antipolis in September 2012, are now available.


The video of the demonstration provided at CCNxCon 2012 is available on YouTube.
