Tutorial
1 (Sunday, June 9, 9:00 am - 12:30 pm)
Design
and Modelling of Medium Access Control Protocols for Wireless Ad Hoc
Networks
Nitin
H. Vaidya, University of Illinois at Urbana-Champaign
Rajive Bagrodia, Scalable Network Technologies
Mineo Takai, University of California at Los Angeles
Description:
This tutorial will provide the attendees with a broad overview of medium
access control (MAC) protocols for wireless ad hoc networks. The
tutorial will consist of two parts. First part of the tutorial will
focus on design of MAC protocols, whereas the second part will discuss
issues related to simulation modelling of wireless MAC protocols. The
tutorial will begin with the challenges in the design of wireless MAC
protocols. This will be followed by taxonomy of wireless MAC protocols.
The tutorial will discuss some representative examples of MAC protocols,
including random access protocols, TDMA protocols, power-conserving MAC
protocols, power-controlled MAC, fair scheduling and priority-based
scheduling, receiver-initiated protocols, MAC for directional antennas,
and adaptive MAC protocols.
Second part of the tutorial will discuss simulation-related issues
including physical layer models, antenna and radio models, propagation
models, modelling of smart antennas, impact of detailed physical models
on protocol performance, and simulation studies of MAC protocol
performance using QualNet simulator.
First part of the tutorial will be presented by Nitin Vaidya, and the
second part by Rajive Bagrodia and Mineo Takai.
Intended
Audience:
This tutorial is designed to provide an overview of issues related to
design of medium access control protocols for wireless ad hoc networks.
The tutorial should benefit researchers as well as practitioners from
industry and academia, who are interested in areas related to wireless
communications, and mobile networking.

Tutorial
2 (Sunday, June 9, 2:00 pm - 5:30 pm)
Routing and Multicasting in Ad Hoc Networks

Lab (ISSL) of HP Labs
Description:
Ad hoc networking, while not a new idea, has received
a lot of attention in the past few years. As such, numerous
new protocols have been developed that
are revolutionizing the way this
communication works. This tutorial will educate the attendees on
the fundamentals of ad hoc networking
technology and research, as well as
the state of the art in this area. We will begin the tutorial with
a description of the characteristics
of wireless ad hoc networks that distinguish
them from their wired and cellular network counterparts. We
will then cover a variety of recent unicast routing approaches. We
will cover proactive, reactive, and
geographical approaches in detail, while
also highlighting clustering, hybrid, and multipath algorithm,
as well as other approaches. We will
then discuss the interactions that
have been observed between MAC and Routing protocols, and how
these interactions affect the behavior
of the routing protocols. Next we
will cover recent multicast proposals, including tree-based,
mesh-based, and geocast techniques. We
will conclude with recent implementation
and standardization efforts, as well as directions for future
research. These include IETF standardization efforts, as well as
research topics such as sensor networks and security. Attendees of
this tutorial will gain an in-depth
understanding of ad hoc networking issues,
as well as of many of the proposed solutions that are likely
to be, or have already been, adopted
by industry.
Intended Audience:
This tutorial is intended for researchers and engineers in both
industry and academia, as well as for
anyone who would like a deeper understanding
of mobile ad hoc networking and the current state of research
in this area. This tutorial is designed to provide an overview
of the issues related to mobile ad hoc networking, as well as
in-depth coverage of current efforts
in enabling unicast and multicast communication
in mobile ad hoc networks.
