Tutorial 1: Optical Networks - High Bandwidth Backbone of the future

(MORNING: 8 A.M. - Noon)

Department of Computer Science
University of South Carolina


Dr. Subir Bandyopadhyay
School of Computer Science
University of Windsor


With the recent rapid growth of internet and corresponding usage of network
applications, the need of network infrastructure capable of delivering at a very
high bandwidth, well beyond the capability of high speed electronic networks, is
urgently being felt. Optical transport media is an ideal candidate to cope with this
high bandwidth requirement, as a fiber's bandwidth can be achieved to be several
order of magnitude higher than that of typical electronic data rate.

Wavelength division multiplexing (WDM) methods applied to optical networks can
achieve this high bandwidth. Such a method allows several WDM communication channels
to be multiplexed on the same fiber hence several end-users operating at electronic
data rate can be supported on a fiber. The tutorial will give an overview of the
capabilities of optical networks using WDM scheme. and different architectures of
such networks to support the expected bandwidth. The tutorial will also present
different routing protocols and the evaluations of the performances of such

Tutorial 3: Web Data Management: Design and Issues

(AFTERNOON: 1 P.M. - 5 P.M.)

The growth of the internet has dramatically changed the way in which
information is managed and accessed. The WWW is a distributed global
information resource. It contains large amount of data relevant to essentially
all domains of human activity. From a user's perspective, it is a broadcast
medium where a wide range of up-to-date information can be obtained at
low-cost. Information on the WWW is important not only to
individual users, but also to business organizations especially when decision
making is concerned. These information are placed independently by different
organization, thus, documents containing related information may appear at
different web-sites. In-house data warehousing may be no longer sufficient to
support an organization's information needs. An executive would also like to
know what information on the web also impact its company.
To overcome limitations of search engines and provide the user with a powerful
and friendly query mechanism for accessing information on the web, the
critical problem is to find effective ways to build web data models and query
languages. Also, to provide an effective mechanism to manipulate these
information of interest to garner additional, useful information. The tutorial
deals with the querying and management of unstructured and semi-structured
data. Here we study the current web data models and query languages to deal
with web data. The key objective is to design and implement a web warehouse
that materializes and manages useful information from the web. In particular,
we discuss building a web warehouse using database approach of managing and
manipulating web warehouse containing strategic information coupled from the
web that may also inter-operate with conventional data warehouses. Some other
aspects of our discussion include web change management and web data mining
and discussion on important open issues.


Target Audience:
This tutorial is designed for academicians and researchers
working in the area of web data management. It is also to help computer and
database professionals/business analysts, such as, database and system
administrators, designers, project and technical managers, people involved in
planning, designing, developing, implementing and administrating internet
data. It is also for students of computer and information science who are
pursuing or planning to pursue a higher research degree. This course will also
address many research problems related to web warehousing technology.

excellent response. He was invited panelist by NSF and in DEXA'99. He was
invited tutorial speaker in ADBIS'99 conference, Brazilian Database Symposium,
1999 and EDBT'2000. He is also invited keynote speaker in Annual Computing

Tutorial 4:  Service Discovery in Ubiquitous Computing Environments

(MORNING: 8 A.M. - 12 P.M.)

Dr. Golden G. Richard III
Dept. of Computer Science
University of New Orleans

Increasingly powerful mobile computing devices and the availability of wireless
networking services are enablers for a wave of ubiquitous computing.  But with
increased mobility comes an increased need for ad hoc connection to important
services, including data storage, delivery of multimedia, printing, fax, and backup.
This need arises out of the requirement that some peripherals be traded for network
services (because of small form factors, limited power) and a desire to eliminate
cabling.  In this tutorial, we will survey a number of service advertisement and
discovery technologies for mobile devices, including Bluetooth, Salutation, and
Jini.  The issues include network protocols, security, power consumption, and the
general advantages and disadvantages of each technology.  An outline of future
research will also be presented.   A brief introduction to mobile computing issues
will set the stage.

Instructor's Biography:

Golden G. Richard III is an Assistant Professor of Computer Science at the
University of New Orleans in Louisiana.  His research interests include mobile
computing, operating systems, and fault tolerance.  Dr. Richard is on the Executive
Committee of the IEEE Technical Committee on the Internet (TCI) and is actively
involved in the organization of several mobile computing and networking conferences.
He is a member of the ACM, IEEE, and is USENIX's Educational Outreach Liaison for
the University of New Orleans.  When he's not hacking, he can be found consuming New
Orleans jazz.

Intended Audience:

This tutorial will appeal to a wide audience, including students, software
developers, and researchers interested in mobile computing issues.  An introduction
to mobile computing (both current technology and research issues) will be provided,
so anyone with a basic computer science background should find this tutorial
