The Internet of Things
I have focused on two main research questions in my career: How can we design and build high-speed networks that support high-performance computing applications that enable discoveries in scientific disciplines such as climate science, genomics, astrophysics, high-energy physics, fusion science, and other such fields? And, how can we design and build trustworthy high-speed, low-latency networks that will constitute the next generation Internet, specifically, the Internet of Things (IoT)? IoT promises to unleash a new variety of applications such as vehicular (autonomous) networking, networked robotics for advanced manufacturing, smart cities and connected communities, smart power grids, and smart health.
Networking and communications have changed immensely. New communications and switching technologies are constantly being developed. We went from having 56 kbps (1 kbps = 103 bits/sec) links in 1988 to 100 Gbps (1 Gbps = 109 bits/sec) today. The implication is that large data files can be transferred very fast between remote computers or other end systems. Also, cellular wireless technologies have advanced through four generations starting from analog service to high-speed LTE today, and 5G is around the corner. WiFi has provided high-speed indoor communications. Simultaneously, applications have developed to take advantage of these higher-speed communication links.
Networking is a field that determines how to interconnect switches and communications links in a manner that accomplishes data transfers between any two endpoints and their applications in a cost-effective manner. Therefore as new communications and switching technologies arise, and/or new applications arise, advances in networking are required to bridge the gap.
The incredible value that the Internet has brought to our daily lives is what makes me excited about working on networks. The opportunity to develop new architectures and protocols that will enable a brand new set of applications is very exciting. New applications include networked manufacturing with industrial robots and 3D printers, improved health care through remote surgery and telemedicine, improved quality of life through sensor data collection and remote actuation in smart cities, improved transportation through vehicular networking, and computer-enabled scientific discoveries.
