Bridging the Information Divide: Challenges & Opportunities
Abstract: 
A large part of our world still does not have meaningful Internet access. The gap between those who have 
quick and easy access to information versus those who do not has created the information divide.  Those 
who have easy access to information generally make better decisions about their livelihood and well-being. 
 Although a symptom of deeper socio-economic issues, appropriate technologies and government policies that 
 take end-user constraints into account can help alleviate this problem.  In this talk, I will discuss 
 research challenges and describe technologies that enable ubiquitous connectivity and services. These 
 technologies range from connecting rural villages in remote areas to monitoring the health of individuals 
 and improving social interactions between people.  I will describe a programmable mobile platform that 
 enables researchers to build and distribute such applications quickly. The problem space is large and 
 complex; to succeed, we have to work together to build affordable technologies that empower the individual.

Abstract: Conserving energy has become the prime objective in any large sensor network. We 
introduce a new paradigm of moving away from such a constraint and advocate the use of an aggregate 
logical sensor unit as a building block. Our objective is to successfully support desired operations in an 
underlying application. This paradigm shift may be feasible if a group of off-the-shelf sensor nodes could 
constitute a logical unit and possess adequate computing power, built-in reliability and cost-effective 
distributed functionality. Such a drastic departure in sensor network design is not easy and we highlight 
various critical issues involved in such an implementation. 
Biography: Dharma P. Agrawal is the Ohio Board of Regents Distinguished Professor of Computer 
Science and Computer Engineering and the Director of the OBR Research Center for Distributed and Mobile

of Cincinnati, OH. He has been a faculty member at Wayne State University, (1977-1982) and North Carolina 
State University, (1982-1998). He received a B.E. in Electrical Engineering from Ravishanker University, 
Raipur, India, in 1966, M.E. (Honors) in Electronics and Communication Engineering from the University of 
Roorkee, Roorkee (now IIT Roorkee), India, in 1968, and the D. Sc. Technology degree in Electrical 
Engineering from the Swiss Federal Institute of Technology, Lausanne, Switzerland, in 1975.  He has 
published over 400 papers in the areas of Parallel System Architecture, Multicomputer Networks, Routing 
Techniques, Parallelism Detection and Scheduling Techniques, Reliability of Real-Time Distributed Systems, 
Modeling of C-MOS Circuits, and Computer Arithmetic and Wireless and Mobile Systems. His recent research 
interests include energy efficient multipath routing, middleware and query processing in sensor networks, 
security in ad hoc and sensor networks, analytical enhancements in IEEE 802.11 protocol, efficient channel 
partitioning in integrated wireless networks, multicasting in integrated wireless networks, interference 
mitigation between Bluetooth and 802.11, routing in scatternet, ad hoc network intrusion detection, 
distributed key management, advanced routing techniques for heterogeneous wireless networks, and use of 
smart multibeam directional antennas for enhanced QoS.
He has been very active professionally. He has been Program Chair and General Chair for many conferences 
and has delivered keynote speech for 5 international conferences. He has received numerous awards from the
 IEEE Computer Society, including the Third Millennium Medal. In 1994, as the Chair of the Technical 
 Committee on Computer Architecture, IEEE Computer Society, he started a new symposium on High Performance 
 Computer Architecture and has become most important meeting for the research community. Recently, he took 
 an initiative in starting a new meeting in Mobile Ad hoc and Sensor Systems area, MASS-2004 held in Fort 
 Lauderdale, October 24-27, 2004. His recent co-authored text book entitled, "Introduction to Wireless and 
 Mobile Systems," has been widely accepted throughout the world and the second edition has just been 
 published. He has four approved patents and fourteen patent filings in the area of wireless cellular 
 networks. He is Fellow of the IEEE,  ACM, AAAS, and WIF. Contact him at dpa@ececs.uc.edu.
