| Overview | My work involving sensor networks focuses on programming interfaces to the user. This includes parallel programming and debugging tools, as well as declarative interfaces. Other work deals with automatic inference and making automatic quality of service trade-offs. Many of these projects involve analysis of a complete system, including aspects of hardware design, wireless networking, calibration, and sensor data analysis. | |||

| Graduate Applicants |
All students must submit a formal application to the Computer Science Department's Ph.D. program to be considered for admission. We do not offer internships. Applicants particularly interested in my research should send a brief email emphasizing your previous publication record and how it relates to specific projects described on my web page. Attach a resume in .pdf format that has links to all publications, including those under submission. Do not send email until after your application is complete, including letters of reference. | |||
| Olsson Hall Wireless Testbed |
The wireless testbed provides researchers a ready to use platform on which to develop and test sensor network applications. It is composed of 50 Tmote Sky nodes placed throughout Olsson Hall

| Clairvoyant: Wireless, Embedded, Source-level Debugging |
 Clairvoyant is the first comprehensive
source-level debugger for WSNs. It provides standard debugging
commands, including break, step, watch, and
backtrace as well as new, special-purpose commands that deal
with interrupts, conditional breakpoints, and new global
commands such as gstop and gcontinue. More...

| FATS Attack: Timing and Fingerprint-based Snooping Attacks |
 We demonstrated
that we can eavesdrop on wireless devices in a home and extract
private information, even when all of the wireless data is encrypted,
with a Fingerprint and Timing-based
Snooping attack, or a FATS attack.
Experiments on four houses demonstrate that we can infer when and how
often the bathroom and kitchen are visited, when the person is
sleeping, and when the home is occupied with 90-100\% accuracy. More...

| MetroNet |
 MetroNet The MetroNet project will consist of sensors deployed in the storefront windows of downtown Charlottesville. The sensors can be used by the store owners, city customers, city planners, real estate customers, etc. More...

| Marionette |
 Marionette is a development
tool for wireless embedded networks. It provides a tight coupling
between the program running on the wireless nodes and a python user
environment, so that the programmer can call functions and read/write
variables on the nodes from within a python shell or script. This
provides unprecedented run-time visibility and control for wireless
embedded devices, and can be used to rapid application prototyping
and/or debugging. More...

| Semantic Streams |
Semantic Streams is a system that allows people to pose
semantic queries over sensor data. It produces logical
interpretations of data, in contrast to most query systems which
produce the data itself or mathematical aggregations of the data,
e.g. the user queries for the number of cars or trucks that pass
through an intersection instead of raw magnetometer values. More...

| Collision Detection |
 This is the first collision detection scheme for wireless
networks. This scheme can 1) differentiate between packet loss due to
collisions vs. bad link quality 2) identify the nodes that caused the
colllision 3) recover one of the packets from the collision. Until
now, all wireless MAC protocols assumed that collision detection was
not possible. More....
