Pervasive Computing Systems Research: An Application-driven Approach

Speaker:  Qi Han – Golden, CO, United States
Topic(s):  Networks and Communications


Pervasive and mobile computing is an emerging field of research that brings in revolutionary paradigms for computing models in the 21st century.  The goal of pervasive computing is to create ambient intelligence where network devices embedded in the environment provide unobtrusive connectivity and services all the time, thus improving human experience and quality of life without explicit awareness of the underlying communications and computing technologies. This talk presents highlights of past successes and current research focus of the PeCS (Pervasive Computing Systems) research group in the Department of Computer Science at the Colorado School of Mines.  In the past, we have designed, implemented, and evaluated algorithms for quality-aware data collection in wireless sensor networks (WSNs). A WSN is an ad-hoc multi-hop network of resource-constrained devices with limited computation, communication, and sensing capabilities.  Different from small-size sensor data, voice data presents additional challenges.  We are the first that have designed algorithms and systems to support quality-aware voice stream multicast over WSNs.   In addition to the basic computer science research, we are also successful in interdisciplinary research. We have developed first-of-a-kind  subsurface contaminant monitoring system using WSNs. In this project, we have made novel contributions in designing a lightweight fault detection service to deal with sensor data uncertainty and algorithms to detect and track amorphous events.  Our current research extends our previous efforts by considering mobility in the system: robotic sensor networks where robot mobility is controllable and participatory sensing systems where human mobility is not controllable. In the second part of the talk, I will describe several of our ongoing projects in these two areas.
