The document summarizes the ReCoop project which aims to exploit cooperative networking mechanisms through developing two technologies: SWIFI and WIZ. SWIFI seeks to create cooperative, wide range Wi-Fi areas through user-provided networking while WIZ aims to provide pervasive Internet access through augmented hotspots. The project is a collaboration between INESC Porto and Nonius Software S.A. funded until 2012 to develop these technologies and improve wireless network access and management.

SWIFI
Motivation
Today
o Cities densely covered by Wi-Fi
o At least 1 Wi-Fi AP per household
o Wi-Fi keeps spreading
o SD cards, SIM cards, Wi-Fi direct
o ICT Demanding society
o Collaborative tools on the rise (e.g.
Facebook)
o New Wi-Fi models emerging (e.g.
FON)
Ubiquitous Cities Emerging
o Global Internet access & data sharing
But
o Centralized infrastructures and IT
o User as consumer
What about
existing Wi-
Fi?
Cooperation
instead of
attempting to
fight back
problems
Wireless
Communities
o Self-organized
o Cooperative
Multiple
Places
o Individual and
Personalized
Experience
De-centralized
Everyplace
Experience
o Individual actions
o Different places
