My research is in the area of networked
computer systems. Over the past few years, my interests have spanned overlay
and peer-to-peer networks; Internet architecture, routing, and congestion
control; wireless and sensor networks; network security; and distributed data
management. A somewhat dated summary (from Fall 2005) of some of my research
and teaching activities is here (5 pages).
I lead the Networks and Mobile Systems (NMS) group at CSAIL. Most of
my papers
and group's software are
available online. My older (pre-1999) papers and software, are also
available.
Current Research
- Wireless networks
- The CarTel mobile sensor network and
telematics system, which includes the Cabernet content delivery network
for vehicles using opportunistic WiFi for connectivity; predictive delay
modeling and traffic-optimized routing, and the Pothole
Patrol (P2) road surface monitoring system, among other efforts.
- Wireless
mesh and sensornet MAC and routing protocols; of late, these involve a
project on Bit-Switched
Wireless Networks, which builds on the SoftPHY abstraction, conflict maps,
and symbol-level network coding for improving wireless concurrency
(spatial reuse) Also
work on various interference mitigation techniques.
- Wavescope: a high data-rate
sensor computing system (joint relational data stream and signal
processing, with high-rate sensornet protocols).
- Network architecture
- Data management systems
- WaveScope
(see above).
Teaching
