Emerging smart cities and other pervasive computing applications promise economical revival, environmental sustainability and in general better quality of life. However, major scalability and energy challenges arise when massive number of sensors and devices are connected to the cloud, which is the destined platform for many applications in the smart city. We propose a novel networking and computing architecture to enable the efficient operation of such cloud-sensor systems. Our architecture, which we call the Cloud, the Edge and Beneath (CEB), aims at suppressing overall system dynamics to maintain acceptable levels of scalability and minimize sensor energy consumption. CEB is an optimization-embedded architecture in which novel guiding principles for optimizations specific to cloud-sensor systems are facilitated architecturally. By infusing distributed optimization within the architecture, we make it possible for sensor data and cloud applications to be part of the choice variables of the online optimization problem. We introduce and utilize sentience efficiency as a precursor to energy efficiency, and present novel bi-directional caching algorithms in which both sensor data and cloud applications are harmonically cached in opposite directions. We present a performance evaluation of the proposed algorithms and show that by utilizing the CEB architecture, the sentience/energy efficiency principles, and the bi-directional caching algorithm, we can achieve superior and unprecedented energy savings in cloud sensor systems.

Seminar Speaker:

Sumi Helal

University of Florida

Abdelsalam (Sumi) Helal is Professor in the CISE Department at the University of Florida, and Director of its Mobile and Pervasive Computing Laboratory. Dr. Helal is also Finland Distinguished Professor - FiDiPro (2011-2014). His active areas of research focus on understanding and enabling cyber-physical computing systems and their human-centric applications. Specifically he and his research team investigate middleware, programming models and methodologies, and architectural issues to define and support the entire lifecycle of smart spaces. From 2001-2007, Dr. Helal served as Director of Technology Development of the University of Florida Rehabilitation Engineering Research Center (RERC) on Aging and Independence. He is co-founder and Director of the Gator Tech Smart House, a large project that aims to identify key barriers and corresponding technological solutions to make the Smart Home concept a common place (creating the "Smart Home in a Box" concept). He is co-founder and an editorial board member of the IEEE Pervasive Computing magazine. He currently serves as Associate Editor in Chief of the IEEE Computer magazine and serves on the editorial board of the IEEE Pervasive Computing magazine.
