    Talk Title: Next-Generation Wireless Networks for Billions of IoT Devices

    Abstract: It is estimated that the total number of Internet of Things (IoT) devices will grow to 80 billion devices in a few years. Unfortunately, existing wireless networks cannot satisfy the diverse requirements of IoT applications in terms of power consumption, data rate, and privacy. Some IoT devices, such as contact sensors used in intrusion detection systems, transmit only a few bytes of data occasionally, while other devices such as virtual reality headsets require a continuous stream of data with a high data rate. Moreover, many IoT devices run on a battery; therefore, they have very strict power consumption requirements. The battery in many IoT devices has to be changed every few months, which is time consuming and costly. Furthermore, old batteries have adverse environmental effects, if not disposed of properly. In addition to these problems, bringing many IoT devices to our smart homes and offices creates many privacy concerns. How can users be confident that their privacy is not violated in smart environments?

    In this talk, I present the design of next generation wireless networks that satisfy the diverse requirements of IoT applications. To enable low-power wireless networking for IoT applications that require low data rates, I present a system that enables a battery-free IoT device to transmit its data to nearby WiFi devices. Next, I describe the design of a low-power and low-cost millimeter wave network for IoT devices that require up to 100 Mbps of bandwidth. Finally, I discuss privacy issues caused by wireless signals transmitted by many IoT devices in a smart environment.
