At the LINK lab, we are exploring techniques and mechanisms to improve efficiency, performance, fault-tolerance, security and other functionality of wireless networks. Using agile and reconfigurable wireless devices, we seek to monitor, manage and protect wireless networks through efficient centralized functions as well as intelligent local actions of individual nodes.

We thank the generous support of a number of funding agencies and industry partners. Our sponsors include National Science Foundation, University of California, Huawei, Intel, Microsoft, Samsung.

Some Ongoing Projects

AIRLAB: Distributed Infrastructure for Wireless Measurements
MERCURY: Trading Platforms for Dynamic Spectrum Distribution
PAPYRUS: Reconfigurable Frequency-agile Radio Testbeds
SAFIRE: Reliable Dynamic Spectrum Access
SOCIAL NETWORKS: Social Graph Modeling
Wireless Data Centers

Recent News : Our ongoing project on building high-speed wireless connections for data centers has been covered by MIT Technology Review, ACM News, ExtremeTech and most recently New York Times. See also UCSB CS News.

Software Release: check out Papyrus and its USRP GNU Radio implementation. We have used papyrus to develop Jello (NSDI’10), a distributed spectrum sharing system to support demanding wireless media applications.
