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.
