Value• no infrastructure• random access• local mixing• gateway• voice advantage• usebed

Current Status• offices • N800• gateways• Separation of UI, mixing and listening

– 90% to 5%

Other Applications• 5000,000 Children’s Laptops(OLPC)

– Mesh Networking enabled– On the fly voice collaboration

• calls without coverage• relay

concerns?

Wouldn’t it be cool if I could listen to everyone in the lab?

Maybe not!

Who’s playing loudmusic at work?

Only Grace has the temerity to do that!

Actually, its D u r g a !!

My reach? Its everywhere!•

You’ve been FluidVoiced!!

Mann last night at the nightclub..psst psst…

Oh! What did I just say? Isn’t FluidVoice on?

It is!!!

To Sum Up• Privacy - someone’s hearing me!• Local mixing - everyone has a mixer.• Identity - who’s allowed?• Inversion of the telephone system -

– Traditional: Point to Point– FV: Many to Many with Point to Point as

special case

• Philosophy - Open the communications space to innovation. 21

Future Work• LG productization• port to N80• deployment at ML• credit based multihop system• separate conversations

UniPlug:A Framework For Ad-hoc Invention sharing

What’s the problem?

• inventions are easily forgotten at MIT

• hard to find

• grandma case!

Invention

• computer programs/software

• diagrams

• websites

• video tutorials

• online Papers

What UniPlug does

• ad-hoc sharing

• detection

• lookup & download

• user populated UniServer

Architecture

• UniClient

• UniServer

• OpenDHT

Models

• Peer-to-Peer

• InterLibrary

• Client-Server

Requirements

• ad-hoc

• populatable

• trust/verification/safetagging

• scalable

Mechanisms

• leader election - fairness

• borrowing - sharing

• locally relevant storage - scale

• context-oriented programming

Context Classification

• User Context(BP)

• Device Context(battery level)

• Surroundings Context(# of wifi networks)

Demo: UniPhone

Demo: UniBlue

UniBlue for Fluidvoice

Security Issues

• trust networks for small communities

• human moderated invention posting

• tagging

• damage control for malicious code released

Medical Devices

To Sum Up

• community advantage of inventions

• context-based

• higher device utilization

• better collaboration

Future Work

• avaya Productization + Patent

• medical devices

• p2p version

• deployment and testing with the MIT community under Living The Future program
