Sensor systems are becoming pervasive in many domains, and are recently being generalized by the Internet of Things (IoT). This wide deployment, however, presents significant security issues. We develop security techniques for sensor systems and IoT, addressing all security management phases. Prior to deployment, the nodes need to be hardened. We…

Providing access to robust connectivity is critical to ensuring today's students are college and career ready. As such, federal, state, and district-level leaders have dedicated a significant amount of time, effort, and resources toward improving our schools' external broadband access, including both Internet access and wide area network (WAN).…

In this dissertation, we present novel physical (PHY) and cross-layer design guidelines and resource adaptation algorithms to improve the security and user experience in the future wireless networks. Physical and cross-layer wireless security measures can provide stronger overall security with high efficiency and can also provide better…
