DFS is a software-based mechanism that targets short-range wireless networks where transmission is based on a shared medium (e.g. broadcast) and which rely on OFDM for data transmission. DFS is applicable downstream, from the antenna to the station, and relies on techniques both from OSI Layer 1 and 2 to assist data transmission to multiple stations within a time-frame that based only in OFDM could only serve the purpose of serving a single station.

 

Environment

 

DFS has been developed as a mac80211 patch for UNIX environments and has been tested successfully on Ubuntu (stations) as well as on OpenWRT (controller).

 

 

The Team

 

DFS has been conceived, validated, and implemented by COPELABS (Rute Sofia and Luis LOpes) and University of Kent (Huseyin Haci, Hassan Osman, Huiling Zhu) in the context of the European project ULOOP - User-centric Wireless Local Loop.

Latest Research

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).
