NDN-OPP: an NDN Opportunistic Framework



The NDN-Opp framework includes some changes in relation to NDN Forward Daemon (NFD) in order to enable social-based information-centric routing over dynamic wireless networks. The first implementation makes use of Wi-Fi direct to exploit wireless transmission opportunities.
  • Forwarding Daemon

Performs the normal forwarding decisions of NDN packets based on their names (UCLA implementation).

  • Connection Manager

Maintains low-level communication channels used by the Opportunistic Faces to effectively transmit packets between UMobile Peers.

  • Router

Fulfills two functions within NDN-Opp

      • Face management:

As UMobile Peers appear and disappear in the vicinity, the Router is in charge of maintaining the state of the corresponding Opportunistic Faces installed in the Forwarding Daemon.

      • Route computation:

In order to improve the forwarding paths used when transmitting packets, the Router runs an algorithm which recomputes the contents of its RIB and FIB based on a variety of indicators pertaining UMobile Peers that it has encountered in the past.

  • Opportunistic Face

Implements the queuing and de-queueing of packets based on the availability of the next-hop.


COPELABS is specifying and investigating how to extend NDN to be applicable in the context of opportunistic wireless environments.

The NDN framework for Opportunistic Networks (NDN-Opp) is being developed aiming to support opportunistic data forwarding based on users’ interests and their dynamic social behavior.

C-BRAIN MeetingsIn 2015/2016, the C-BRAIN (COPELABS BRAINstorming) meetings occur monthly, Tuesdays, 14h00-15h30, COPELABS, room U.0.10, ground floor of Building U, University Lusofona. C-BRAINs are motivated by the interdisciplinary nature of COPELABS, and are intended to assist in creating sinergies and giving rise to new ideas, in contexts where Informatics meets Psychology.

ummOur scientific repository holds the most recent work. COPELABS follows a pre-print open policy.

SITI - Informatics Systems and Technologies Group

SITI w400SITI is focused upon user-centric trends that are emerging in several fields of Information and Communication Technology (ICT), OSI Layers 2 and 3. As in other grassroots movements, the user will have an active say concerning services provided and consequently, concerning the techno-social environment that surrounds him/her.

CTIP - Technology Intensive Psychology Group

CTIP w400This group is based (i.e. integrated members) on a core of scientifically active researchers from the former CEPCA (Pedro Gamito, Jorge Oliveira, Rodrigo Brito, Paulo Lopes, and Ana Loureiro) 2 more recent PhDs (Cristina Camilo and Bárbara Gonzalez). Note, however, that the CEPCA team (team size, funding and indicators included in 5.) changed substantially since 2008, when it had 8 PhDs (of which only PG remains) and 5 groups. In 2011-13 the team grew to 14 integrated PhDs in 2-3 groups. By 2013, however, it was clear that the bulk of CEPCA output of international level (13 of the 14 indicators in table 5.) was the responsibility of the neurocognitive/cyber therapy-focused group, with only 3 PhD and 2 non-PhD members (PI: PG). The inevitable consolidation of CEPCA around this core group pointed to the desirability of joining forces with an informatics team – SITILABS – to create COPELABS as an interdisciplinary R&D unit (see Description of the R&D unit).
