Viral Communications

Challenge:

What does it mean for humans to be able to construct networks shaped by their

natural communities?

Viral Networks

Scalable

Incremental

Value-Enabling

Socially-Constructed, User-driven

Viral Communications

Viral Technologies Explored

Radio Magic – radio networks that cooperate by sensing and adapting to their physical environment and user needs – software-defined physical layer radio

Peer Multicast – exploit “gossip”

Multiconnectivity – every device has many interfaces

Viral Overlay – build on what's already there

Contributory infrastructure – to share the answer

Viral Communications

Radio MagicMelange – a wireless LAN protocol that exploits

the capabilities of GNU software radio platform, more scalable and adaptable than WiFi.

Multiple Identity – user-controlled RFID, allowing users to negotiate with their institutional environment

Viral Communications

Peer MulticastTV Rewired – peer-to-peer, real-time content distribution

without servers, providing resilient and scalable distribution for communities of any size and scale

Snap and Share – asynchronous multicast of information based on opportunities to connect

Fluid Voice - “pull to listen” - put the receivers in control of conferencing and collaboration

Xcast – peer-to-peer local content production and distribution

Viral Communications

Contributory InfrastructureXO Mesh – exploiting and scaling the mesh

network built into the $100 laptop, to meet the needs of kids

Community Storage – serverless storage that packs 10 lbs of books in a 3 lb laptop

UniPlug – community contributes the means to construct multi-device systems

Viral Communications

ThemesIntelligence is cheap and fast and portable

(sense, adapt, evolve)

The network context exists everywhere

(context can be presumed)

Can put the user or endpoint back in charge

Viral Communications

Viral Overlay

• Virtual Mobile Internet - “proto LTF”– Virtualize heterogeneous transport– Virtualize location

• Peers: Overlay peer-to-peer stream distribution

• Loops: Overlay distributed event and sensor data distribution

Viral Communications

Liquidity of connection

• MIT Internet• MIT MVNO• “WiMax/Mesh” to

Boston/Cambridge• Spot beams

Page 12: Viral Communications Viral Comms WG: The Viral Community David P. Reed Andy Lippman May, 2007.

Viral Communications

Liquidity of identity• “Personal router”• Initially embodied

in Amulet• User-controlled

identity and interaction

Viral Communications

Liquid context & environment• UniPlug adapts

“legacy” technology• Contributory –

everyone in community helps

Viral Communications

Looking forward: Multiconnectivity

• Laptops, phones have multiple radios• Environment has multiple “access

modes”• SDR coming into its own• “Tussle” for control of/by the individual• Explore: how to choose mode based on

context and goal
