Abstract
Mesh networks have become increasingly important because they can be easily
implemented without much infrastructure and can support adequate bandwidth with a flexible
multi-hop wireless communication among their routers serving the clients. This tutorial provides
an overview of the Wireless Mesh Networks (WMNs) and identifies various associated
characteristics. The very first problem faced in the WMN design is how many mesh routers
(MRs) to be deployed and where should they be placed. Another related question is how many
MRs ought to be used as the Internet Gate Ways (IGWs) and where they should be located. Other
issues such as route determination, channel allocation, load-balancing, etc. have to be considered
carefully to have a clear understanding of the WMN technology. Issues such as selfishness and its
impact on the performance will be discussed. Useful research directions will also be clearly
identified. Future widespread deployment of the WMN seems quite promising, even though
security and scalability questions still remain real bottlenecks.
Biography
Dharma P. Agrawal is the Ohio Board of Regents Distinguished Professor of Computer Science
and the founding director for the Center for Distributed and Mobile Computing in the Department
of Computer Science. He has been a faculty member at the ECE Dept., Carnegie Mellon
University (on sabbatical leave), N.C. State University, Raleigh and the Wayne State University.
His current research interests include resource allocation in wireless mesh networks, query
processing and secured communication in sensor networks, environmental monitoring using
sensor networks, and effective traffic handling in integrated wireless networks. He has published
several books and over 500 papers. His recent co-authored textbook on Introduction to Wireless
and Mobile Systems published by Thomson, has been adopted through the world and has been
reprinted in both China and India as well as translated in both Korean and Chinese languages. His
second co-authored book Ad hoc and Sensor Networks- Theory and Applications has been
published by World Scientific in Spring 2006. He is an editor for the Journal of Parallel and
Distributed Systems, founding Editorial Board Member, International Journal on Distributed
Sensor Networks, International Journal of Ad Hoc and Ubiquitous Computing (IJAHUC),
International Journal of Ad Hoc & Sensor Wireless Networks and the Journal of Information
Assurance and Security (JIAS). He has served as an editor of the IEEE Computer magazine, and
the IEEE Transactions on Computers and the International Journal of High Speed Computing.
He has been the Program Chair and General Chair for numerous international conferences and
meetings. He has received numerous certificates from the IEEE Computer Society. He was
awarded a Third Millennium Medal, by the IEEE for his outstanding contributions. He has also
delivered keynote speech for six international conferences. He has been named as an ISI Highly
Cited Researcher and is a Fellow of the IEEE, the ACM, the AAAS and the World Innovation
Foundation.
