Cross-technology Communication: Turning wireless interference to interconnection

  • Speaker: Dr. Song Min Kim
  • George Mason University
  • Date: Friday, Dec. 8, 2017
  • Time: 1:00pm - 2:00pm
  • Location: Room T3 (NVC)


IoT (Internet of Things) is anticipated to significantly improve the qualities of our daily lives in the areas of home automation, healthcare, and transportation, among many others. This is achieved by massive and diverse wireless devices covering every corner of our living space. This talk introduces intelligent IoT networking via the latest technique of cross-technology communication (CTC) - a new set of designs that establishes direct communication between commercial devices with incompatible wireless physical layers (e.g., WiFi, Bluetooth, and ZigBee), essentially turning interference to interconnection. CTC is a key enabler to achieving pervasive connectivity and distributive exploitation of collaborative opportunities among heterogeneous and specialized networks, to enhance IoT beyond the current practice of isolated operation. The talk will first introduce the basic concept and rationale behind CTC. Then, I will discuss distinct design principles of state-of-the-art CTC; Specifically, low-rate transparent packet-level CTC and the new high-speed physical-layer CTC, followed by their advantages and limitations. Finally, I will present CTC's potential applications/services and their impact to the IoT.
