Abstract:
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
protocols

Broad Overview of the Tutorial:
The basic principle of wavelength division multiplexing techniques and
its
advantages of WDM scheme with other multiplexing methods
Different architectures, wavelength assignment and routing principles
Role of physical and logical topologies in efficient routing algorithms
Comparative studies of different routing schemes and their performances

Abstract:
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.

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

Intended Audience:
This tutorial will appeal to a wide audience, including students, software
developers, and researchers interested in mobile computing issues.
