  Edge computing as a new computing paradigm pushes the frontier of computation, data, and services away from centralized servers to the edge. With the rapid growth in Internet-of-Things (IoT) applications, edge computing is playing an ever more important role in addressing the needs for lowering communication bandwidth, increasing security/privacy and narrowing digital divide. However, edge computing faces many challenges such as severely limited resources, huge diversity in resource types, rapidly changing resources, and scalability. Furthermore, since edge computing must closely interact with physical systems, it usually has to deal with stringent real-time requirements. Tackling these challenges require coordinated efforts in hardware, system as well as application software developments.

  In this talk, I use two specfic application domains that exploit edge computing to highlight some of our research efforts. The first is social sensing where humans and devices on their behalf are used as “sensors” to collect real-time measurements about the physical world. I will present techniques on how to solve the critical problem of allocating delay-sensitive social sensing tasks to heterogeneous edge computing devices. The other domain is intelligent healthcare where energy-efficient system is needed to handle demanding computational workloads. I elaborate the development of hardware-cognizant machine learning algorithms for biomedical image segmentation. I will end the talk summarizing our other efforts in this exciting area of research.
