From Wireless Networking to Smart Computing: Challenges and Solutions
The last decade has seen tremendous advancements in computer science and engineering
such as wireless networks, mobile and pervasive computing, sensor networks, information mining,
ambient intelligence, human-centered computing, middleware, and so on. Such technologies
have made the world closer and our life experience better than ever as we live in an increasingly
connected and automated society that links devices, computing and communication platforms to
everyday tasks and settings. As a result, recently there has been an upsurge of multi-disciplinary
research projects on the design and development of smart computing environments. We define a
"smart environment" as one that is able to autonomously acquire and apply knowledge about a
sensor-driven environment, and adapt to user preferences to improve their experience without
In this talk, we will first give a brief overview of emerging research directions in wireless mobile,
sensor and pervasive networks. Next we will discuss fundamental challenges and issues in the design
and modeling of smart environments. We will also present a novel framework for tracking user contexts
(e.g., activity, location) as captured by sensors while users interact with the environment on a daily
basis, thus leading to intelligence automation, autonomic and context-aware computing. Our fundamental
approach and models are based on solid foundation such as information theory, text compression,
on-line learning, uncertainty reasoning, and game theory. The proposed models will be validated with
the help of an agent based architecture and tools that we developed. The talk will be concluded with
open research problems and future directions in this field.
