CNDS - Xarxes de Computadors i Sistemes Distribuïts

 

Les xarxes comunitàries busquen una xarxa oberta, lliure i neutral aplicant el principi de
reciprocitat a la interconnexió de nodes per la circulació de continguts i serveis. El grup
investiga on Xarxes Comunitàries (Community Networks), Computació en Núvol Comunitària
(Community Clouds) i Xarxes De Sensors Sense Fils Comunitàries (Community Wireless Sensor
Networks).
