Title: Public Computing - Challenges and Solutions
Abstract:
Public computing is a type of grid computing architectures composed of autonomous
volunteer workstations coordinated by a central server complex over the Internet.
Exploiting these distributed resources comes at the price of unpredictable availability,
fluctuating performance, and heterogeneous participant nodes. Central to addressing these
problems is an efficient and accurate scheduling mechanism for the public computing architecture.
In this talk, I will overview grid computing in general and a public computing platform called
BOINC in particular. Several major issues and challenges in grid computing research will be
identified. I will also report our new research results in this exciting area through introducing
a scheduling system based on the ant colony algorithm. In addition, the bottleneck problem in
the client-server architecture used in BOINC will be identified and a new peer-to-peer architecture
for solving the problem will be presented. Several applications have been implemented on BOINC
and our new architecture using our scheduling system. By testing these applications with totally
different characteristics, we show that our scheduling system consistently provides a high
performance, adaptive solution to all of them, and the system using our new peer-to-peer
architecture indeed performs better than BOINC. Our work also manifests that public computing
can solve the problems of large computing power requirement and huge memory demand in many
applications and potentially replace supercomputing for certain applications in the future.

Title: Filling the Generation Gap - Convergence in Wireless Networking
Abstract:
Wireless networking technologies have progressed rapidly over the past decades to emerge from research laboratories
and become an integral part of everyday life in society. Over a short time span of less than twenty years,
cellular networks have advanced through three generations. The third generation (3G) personal
communication service (PCS) networks that have been rolling out in the new millennium are leading
the way in service convergence, by extending not only voice service, but also messaging, web,
and even television services to mobile subscribers. At the same time, many license-free wireless
networking technologies such as wireless metropolitan area networks (WMANs), wireless local area
networks (WLANs) and wireless personal area networks (WPANs) have emerged and are providing strong
competitions to PCS offered by traditional wireless carriers. Where the road of progress in wireless
networking services will lead us, and what technologies will be embraced in future generation
wireless networks, are timely questions that both researchers and practitioners are trying to answer.
There is now a strong consensus in the wireless networking technical community that the next
generation wireless networks will be evolutionary and will embrace multiple wireless technologies
and system components built upon a common IP core network. It is envisaged that advanced subscriber
terminals will be equipped with multiple or smart radio interfaces, and will interact with several
alternate access networks to provide the subscriber with an "always best connected" (ABC) service
that is cognizant of the requirements of the subscriber's current application and the capability
and quality of service supported by the diverse access alternatives. The convergent of multiple
wireless networking technologies to provide a coordinated service to mobile subscribers can therefore
be considered a technological trend that is filling the generation gap in wireless networking.
This presentation will describe the features and characteristics of converged wireless networks,
elaborate on some of the technical challenges that need to be tackled to make ABC service over
converged wireless networks a reality, and describe several novel solutions we have developed to
address these challenges.

Title: Designing the Future Internet
Abstract:
The Internet, the greatest technological invention of our times, has
become a necessity in every sector of our society. Nevertheless, the
network architecture of the Internet is reaching its limits, so we
must find new ways to improve its security, mobility, and
accessibility. The research community is working to design the
Internet of the twenty-first century, by focusing on the desirable
architectural functionalities. The approach gaining general
consensus is the "clean slate" one, which is unconstrained by the
properties of today's Internet. In this talk I will identify several
problems with today's Internet, as well as major issues and
challenges about the design of the Future Internet. The next
generation Internet has to be commerce friendly and secure. It
should allow receivers to set policies for how and where they
receive their information. The next generation Internet should be
designed for mobile objects. Naming, addressing architecture, and
routing have to be such that these objects can move and decide how
and where they want to receive their Internet traffic with full
rights of privacy of their location, if desired. I will continue
with an overview of major ongoing efforts designing the various
aspects of the Future Internet's architecture. I will also talk
about our ideas and solutions for a new networking architecture. Our
framework is based on a recursive hierarchy of realms, which follows
the organizational structure of commercial organizations. The new
architecture enables network scalability, service flexibility, node
mobility and personalized security.
