Welcome
Informal, local event today Formal, global event is annual open house
in August every year starting 2010
Current Status: Research projects Staff hiring Equipment purchase Publicity Outreach

Theory and Practice “There is nothing more practical than a good theory” “Theory as the brain and systems as the heart” “Rigor or relevance: either but not both?” “Relevant question or elegant answer?” …
Why theory is inalienable: Explanatory (rather than descriptive) models Top-down design with predictive power
Why theory is incomplete: Sensitivity to math crystallization Need to make a difference in live networks

Not Just Yet Another Testbed
1. Focus on edge networking (rather than backbone and sensor networks)
2. Theory-inspired implementation: Validate predictions Falsify assumptions Tighten characterizations Inspire new questions
Technology transfers Innovation incubation Student education

Research -- Motivations
Networked end users with access that is Universal (Politically) Free Shared Scalable (Economically) Sustainable
10
Research -- Topics
Social Content distribution and sharing Content pipe divide Online social networks Internet for freedom Economic policies
Clean Price of greening Healthcare wireless delivery
Edge End user oriented Access and home networks
11
Research -- Projects
Network optimization Dynamics of information in networks via
geometry Content aware networking P2P global streaming Utility Optimal CSMA Socio-Tech networking SharingMart FreedomNet Network economics Green IT
12
The Language is MathMethodologies: Distributed optimization Stochastic control Games and economics Graphs and random processes…
Functionalities: Power control and scheduling Congestion control and routing Topology control and distribution Pricing…
13
Research -- Grand Challenges
How to deal with nonconvexity? How to be robust and opportunistic to
dynamics? How to reduce high dimensionality?
14
Research -- Grand Challenges
1Mbps global P2P streaming Near optimal scheduling without message
passing Tunable control of content-pipe mutual
awareness Universal broadband coverage Protect end user from central authorities Price user-generated content online Distribute and recover the price of greening
