Push the Limits of Wireless Connectivity for IoT Devices

12:00 - 1:20 PM in COB 263

Host: Dr. Wan Du


One vision of Internet of Things (IoT) is to provide seamless connectivity for everyday objects. IoT devices are deployed densely in space to enable ubiquitous intelligence; and are connected wirelessly to support frequent data exchange. These devices are also becoming increasingly mobile, such as IoT-powered inventory management, personal robots and autonomous cars. However, the current network stack lacks primitives to support the desired connectivity, management and services of IoT devices. In this talk I will present two solutions to push the limits of connectivity for IoT devices. The first system, Wi-Fi Goes to Town, provides seamless wireless connectivity for high speed automobiles by very small wireless cells. The second system, PLoRa, enables long-range backscatter communication for low-power IoT devices by hardware-software co-design. Finally, I will conclude with a future research vision centered around building secure and scalable IoT systems.
