Challenge: What does it mean for humans to be able to construct networks shaped by their natural communities? Viral Communications

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 Magic Melange – a wireless LAN protocol that exploits the capabilities of GNU software radio platform, more scalable and adaptable than Wi. Fi. Multiple Identity – user-controlled RFID, allowing users to negotiate with their institutional environment Viral Communications

Peer Multicast TV 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 Infrastructure XO 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 Uni. Plug – community contributes the means to construct multi-device systems Viral Communications

Themes Intelligence 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

A Viral Proto-LTF PCS Data Carrier interface; Carrier integration; portable platforms; MIT-MVNO; development env MIT gateway Campus Wi. Max testbed; accessible processing; Spot beam “Cooperative SDR” Virtual Mobile Internet; Peers; Loops; Unified Sensors; Unified Identity & Auth Viral Communications

Liquidity of connection • MIT Internet • MIT MVNO • “Wi. Max/Mesh” to Boston/Cambridge • Spot beams Viral Communications

Liquidity of identity • “Personal router” • Initially embodied in Amulet • User-controlled identity and interaction Viral Communications

Liquid context & environment • Uni. Plug 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 Viral Communications
