The location for MobiCom'97 is the Palace of the Hungarian Academy of
Sciences. The Academy is the most prestigious scientific institution in
Hungary, and the Palace, the central building of the Academy, is one of
the most beautiful buildings in Budapest. It is located on the Pest side
of Budapest, east of the Danube River, near the Chain Bridge. The Palace
overlooks the northern end of Roosevelt Square, along the embankment of
the Danube River. Built between 1861 and 1865, this neo-Renaissance
building is decorated, both inside and outside, with sculptures and
wall-paintings by the most outstanding Hungarian artists of the age.
The conference hotels are all located nearby, and many of the sights
and shops of Budapest are within easy walking distance.

Budapest is easily reached by air, rail, road, or river. Budapest's
airport is served by a number of major world airlines, with nonstop
flights from many foreign cities. For transportation from the airport
to your hotel, we suggest the LRI MINIBUS Service. The information desk
for this shuttle service is located in the center of the airport arrival
lobby. You can order this service inside the baggage claim area as well.
The price of the shuttle is 1200 Hungarian Forint (HUF) per person
(approximately US $7-8) one way.

Citizens of some countries may require entry visas to visit Hungary. No
visa is needed for citizens of the USA, Canada, or any of the European
countries, except Albania, Turkey, Kazakhstan, and Uzbekistan. A visa is
needed for citizens of Japan and Australia. If in doubt, please check

TUTORIAL 1
----------

Wireless ATM: Standards, Architectures, Protocols & Implementation

Dr. Lou Dellaverson (Motorola, USA),
Dr. C.-K. Toh (Hughes Research Laboratories, USA),
and Dr. Arup Acharya (NEC, USA)

Friday, September 26
8:30am - 5:00pm

ATM is currently viewed as the next high speed integrated network paradigm,
supporting different classes of traffic and providing quality of service.
Mobile communications have evolved and created a significant impact on the
way we work and communicate. The convergence of mobile communications,
computing, and ATM gives rise to Wireles ATM networks. While ATM helps to
bring multimedia to the desktop, Wireless ATM provides similar services to
mobile computers and devices. In addition, Wireless ATM networks provide
seamless integration with ATM-based B-ISDN networks.

This tutorial will cover system-level architectures for mobile/wireless ATM
with necessary radio protocols for wireless ATM access and networking
protocols to support mobility management. Standardization activity within
the ATM Forum's WATM group will be presented along with implementation
experience from research prototypes of mobile and wireless ATM. This
tutorial will not only benefit researchers, professors, students, but also
consultants, network engineers and managers who wish to acquire the
knowledge and practical know-how on Wireless ATM.

TUTORIAL 2
----------

Mobile IP: Adding Mobility to the Internet

Charles E. Perkins (Sun Microsystems, USA)

Friday, September 26
8:30am - 5:00pm

The Internet is growing by leaps and bounds, and likewise mobile computers
are becoming more and more popular. When mobile computers move and attach
themselves to new networks within the Internet, they can use Mobile IP as a
means to achieve seamless roaming transparently to application software.
In this situation, transparent means that the applications work just as
before and don't need to be recompiled or reconfigured. Seamless means
that roaming from one place to another occurs without inconvenience to the
user. As long as a physical communication path exists, the user might not
even be aware when movement has happened. The objective of this tutorial
is to lay out all the necessary protocol technology to allow mobile
computers to use Mobile IP, and to describe the relevant operation of
other protocols which can be used to aid mobility, such as DHCP and
Service Location Protocol.

Topics that will be covered include Agent Advertisements, registration
procedures, tunneling mechanisms, the role of security, and home agents and
foreign agents. We will also cover how to set up a home network, getting
care-of addresses via DHCP, Route Optimization, smooth handoffs, IPv6
mobility support, and the Service Location Protocol. In addition, we will
look at an architectural model for supporting nomadic users under
development within the Cross-Industry Working Team (XIWT) in the
"Nomadicity" group.

TUTORIAL 3
----------

Simulation of Large Mobile Wireless Networks

Prof. Rajive Bagrodia and Prof. Mario Gerla
(University of California at Los Angeles, USA)

Saturday, September 27
8:30am - 5:00pm

Protocols for wireless networks are complex to design, evaluate and
implement. Their performance depends on a combination of factors that
include multimedia traffic patterns, mobility models, application
objectives, processor characteristics, and radio characteristics.
Evaluation of a protocol as a function of these diverse parameters is
analytically intractable. Given the complexity of the radio environment,
sequential simulation of networks with thousands of nodes requires several
days, and perhaps, even weeks. To make the design more interactive, it is
imperative to reduce the turnaround time for the models. The goal of this
tutorial is to describe efficient simulation techniques for very large
mobile wireless networks and to present some representative case studies.
The environment has been built using the Maisie simulation language at UCLA.

A number of approaches to reducing the simulation time for such models will
be presented including parallel simulation, hierarchical modeling, and
multi-paradigm models. The tutorial will begin with an overview of
existing simulators, including OPNET, Bones, and other commercial products.
The primary emphasis of the tutorial is on presenting the use of Maisie for
parallel simulation of network models and their subsequent porting into
physical implementation. The sources of overhead in the parallel execution
of network models will be discussed together with methods to reduce their
impact. Common pitfalls encountered in the design of parallel simulation
models will be discussed. We will also describe techniques to port
simulation models to protocol implementations. Finally, a number of case
studies will be presented to highlight the lessons that have been learned in
the design, simulation, and implementation of wireless network protocols.

TUTORIAL 4
----------

Cellular Wireless Networks: Principles and Operation

Prof. Zygmunt J. Haas (Cornell University, USA)

Saturday, September 27
8:30am - 12:00pm

This tutorial addresses the basic networking concepts of mobile cellular and
wireless networks, exposing both the theoretical and practical aspects of
mobile communication. As an introduction, basic enabling technology will be
presented, such as the cellular principle and multiple access technologies
(e.g., CDMA). Following this introduction to mobile radio, we will
investigate the underlying techniques used in design and operation of
cellular networks, including handoff schemes, channel assignment and power
control algorithms, common-air protocols (e.g., IS-54/136, IS-95, GSM,
etc.), and microcellular architectures. Some more advanced concepts, such
as macrodiversity and multi-tier wireless networks, will be briefly
discussed. Next, we will address the subject of user mobility support in
the wireless environment. In particular, call processing functions, which
include roaming, routing, and registration, will be explained. The
differences between mobility management in data networks and in voice
networks will be clarified. As an example, a comparison of the Cellular
Digital Packet Data (CDPD) and Internet mobility support through Mobile IP
will be presented. The tutorial will be augmented with abundance of
examples from existing and proposed future wireless networks. The tutorial
is targeted towards broad audience, both from the academic and the
industrial environments.

TUTORIAL 5
----------

Disconnected and Weakly Connected Access to the World Wide Web:
Issues and Techniques

Dr. Murray S. Mazer (Open Group Research Institute, USA)

Saturday, September 27
1:30pm - 5:00pm

This tutorial addresses the concepts, issues, and techniques involved in
supporting weakly connected and disconnected access to Web-based information
resources. ``Access'' includes both reading and writing - in addition to
continuing to browse under diminished bandwidth conditions, the user may
wish to create or change content, having it integrated back into the Web
when the connectivity is sufficient. As background, we will review
techniques used for disconnected and weakly connected access to
network-based file systems. We will compare and contrast file systems and
the World Wide Web, pointing out numerous ways in which the two types of
information systems differ (and how those differences affect the adaptation
of techniques from the file system space to the Web space). The tutorial
will include a review of systems for "off-line browsing" (a.k.a.
disconnected reading) and for filtering requests and responses to adapt to
changing bandwidth conditions. We will address issues, techniques, and
limitations regarding architectural choices, meta-data requirements, data
management, "weblet" management, consistency, pre-fetching policies, change
staging and integration, content transformation, security, user
expectations, and other relevant topics. We will also discuss the impact
of HTTP1.1 and other topical standards.
