Viral Innovation
Scalable Incremental Contributory
Viral systems are innovative through modularity
and distribution of capability -- the
intelligence is at the ends e.g. Fax machines,
Internet
3
Viral Radio
Open systems such as PCs gain capacity with more
units, traditional communications systems divide
fixed capacity among elements. Can we make
communications systems (telephones, networks)
that are viral and economic?

Questions, etc
Radio Can we do it? Who benefits,
how? Distributed systems Where to go P-P,
sensing Outside in Broadband explore with
Sharon? Where do you fit? Open issues
robustness Yochai issue can we consider social
software dimensions of making viral systems.

and actuating networks for verifiable, secure,
extensible systems Applications to bulidings,
traffic, broadband 1 year Available parts DL,
CFP Open partners

Interaction Agenda
Map our work into new domains Focus or modify the
work plan Regulatory Interactions Economic and
security models
13
Radio Magic
Radios costing less than radio waves
(Breadcrumbs) There are no receivers (Receiving
costs more than transmitting)
Collaboration makes it work

Lesson of 2004 Propagation
Free space is well known, other cases are not
15
Lesson of 2004 Propagation
(1) Fill the space with radios (versus power) (2)
They determine best case relay (3) Diversity
allows two to win (4) Decoderless relay
