2. WONS 2011 – Bardonecchia, IT, Jan 26-28, 2011 locigno@disi.unitn.it 2 Agenda A retrospective on communications  Electrical  Human Short Radio Communications  What are they (you know, otherwise you won’t be here)  What they can (should?) become Foundational Issues  Some crazy ideas I don’t know how to tackle

9. WONS 2011 – Bardonecchia, IT, Jan 26-28, 2011 locigno@disi.unitn.it 9 Short Range Communications Tomorrow Reverse the logic of networking  Remember the spinning figures?

10. WONS 2011 – Bardonecchia, IT, Jan 26-28, 2011 locigno@disi.unitn.it 10 Short Range Communications Tomorrow Augmented human communications  Local direct contacts  Group communications Avoid global networking for local communications  More than Ad Hoc  Must be a “global” local communication Provide support for the non-verbal, non- formal communications  Trust, Consensus,...

11. WONS 2011 – Bardonecchia, IT, Jan 26-28, 2011 locigno@disi.unitn.it 11 SRC: Toward Social Glue Help reconstructing “communities”  Connect locally, communicate here Reverse the “google syndrome”  Trust your community not (commercial) recommending systems Reduce the digital divide  Go back to a less “technocratic” language

Group authentication Anonymous/Pseudonymous communications for some tasks
