UMM: User-centric Mobility Management (05.2010-08.2013)

COPELABS Coordination: Rute Sofia


UMM (User-centric Mobility Management) is a project focused on global mobility management in spontaneous wireless environments, i.e., environments that self-adjust to any network topology change. Global mobility management is addressed from a network perspective, and the purpose is to ensure a transparent access to Internet services (e.g Triple Play) for the end-user, who will be able to access his/her subscribed services independently from access attachment point, location, and based upon his/her own requirements (“Quality of Experience”, QoE). In addition, global mobility management is to be analyzed from a de-centralized perspective, given that environments to be considered will incorporate wireless local-loops that are based upon end-user willingness to cooperate.


The project has been coordinated by COPELABS, SITI, and had as participating entity Institute of Telecommunications in Aveiro. The project was sponsored by Fundacao para a CIencia e Tecnologia between 2010 and 2013.

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.

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).
