I'm the Fujitsu Professor in the EECS Department at MIT and lead the Networks and Mobile Systems group at CSAIL. I also work closely with the
database group. My research is in the area of networked computer
systems. My work has spanned wireless networks and mobile computing,
overlay and P2P networks, Internet architecture, routing, and
congestion control, network security and privacy, and data management.
Short bio.
My students and I are members of the recently launched MIT Center for Wireless Networks and
Mobile Computing, aka Wireless@MIT.
My papers and group's software.
My older
(pre-1999) older papers and
software.
Current Research
- Spinal codes and rateless wireless networks
- Adaptive and gracefully-mobile applications & protocols
- Mosh, the mobile shell, an example
of a "first-principles" architecture for interactive remote terminals.
- Alfalfa, a system for
interactive videoconferencing over wireless cellular networks, another
example of a gracefully-mobile application (this one is high-bandwidth
and low-delay, whereas Mosh is low-delay but not as
bandwidth-intensive.
- Inferential transmission control, a new plan for congestion management for more evolvable networks.
- CryptDB, a system to run
SQL over fully encrypted data without requiring clients to perform any
query processing themselves.
- System software for "truly mobile" devices including:
- CarTel, a mobile sensor
system motivated by vehicular and transportation applications. CarTel
applications can collect, process, deliver, analyze, and visualize
data from sensors located on mobile units such as automobiles and
smartphones. Component projects include accurate delay estimation
(Vtrack
and CTrack); the
Cabernet
content delivery network for vehicles using opportunistic WiFi for
connectivity; predictive delay modeling and traffic-aware stochastic
routing (soon available on the iPhone as iCartel); various
privacy
protocols for tolling, insurance, and statistics gathering; the
Pothole
Patrol road surface monitoring system; etc.
Also check out our iPhone app, iCarTel!
