Tutorials
- Tutorial Session I: Compressive Sensing Theory and Applications
by Volkan Cevher and Richard Baraniuk (Rice University)
Time: April 16,2009 Thursday 8:30AM~11:30AM
Abstract: Compressive sensing (CS) is a new approach to
simultaneous sensing and compression that enables a potentially
large reduction in the sampling, communication and computation costs
at a sensor for signals having a sparse representation in some
basis. The CS measurement process is non-adaptive, and the recovery
process is nonlinear, for which a variety of algorithms have been
proposed.
The goal of this tutorial is to expose the CS theory to a wide
audience in academia and industry who are interested in information
processing in sensing systems. The tutorial will present the
fundamentals of CS in an approachable manner, aiming to encourage
engineers in industry and academia to exploit the new theory in
their applications and their research. Although several theoretical
results will be presented, the emphasis is on the intuition and the
understanding of the theory.
The target audience level is the same as the target audience of the
IEEE Signal Processing Magazine.
- Tutorial Session II: TinyOS 2.1 (introduction and new features)
by Omprakash Gnawali (University of Southern California)
Time: April 16,2009 Thursday 8:30AM~11:30AM
Abstract: TinyOS is an operating system widely used in sensor
network research in academia and industry. In this tutorial, we will
explain the details of TinyOS 2.1 architecture and learn how to
start using TinyOS 2.1 for research and sensor network application
development. This tutorial presents: a) an overview of TinyOS 2.1
component-based architecture and design rationale, b) the details of
nesC, the C-dialect used to write programs in TinyOS, c) mechanisms
to trap memory access errors (null pointer dereferences, array bound
violations, etc.) using Safe TinyOS, d) an overview of TinyOS
threads which enables seamless interleaving of long running
background computations with time critical event-based services, and
e) a survey of the TinyOS network stack. The tutorial will include
hands-on session during which the participants will learn about
TOSSIM, the TinyOS simulator, and run TinyOS programs.
Requisites for the hands on session - Bootable CD drive.
- Tutorial Session III: Energy Metering and Tracking with ICount and
Quanto
by Rodrigo Fonseca (Brown University) and Prabal Dutta
(University of California, Bekerly) and Thomas Schmid
(University of California, Los Angeles)
Time: April 16,2009
Thursday 1:00PM~5:00PM
Abstract: This tutorial will show, using a
hands-on approach, how application programmers can instrument their
TinyOS applications to measure energy usage broken down by hardware
component (e.g. MCU, radio, flash, sensors), logical activity (e.g.
sensing, storage, routing, network programming), or time. The
tutorial will show how the iCount energy metering hardware, the
Quanto tracing framework, and set of software tools, can be used to
ask such questions and interpret the results. The tutorial will also
cover how system programmers can instrument system components and
device drivers to integrate with the framework.
Applying these techniques, students will be able to answer
simple questions like, "How much energy and CPU time is used for
Blink?" to more complex questions like, "What is the network-wide
cost of a flood?" Each participant will be able to use one provided
Quanto Testbed Mote, based on Epic, equipped with iCount, and
programmable over the network. The tutorial will combine
presentations using overhead slides with short practical activities
on the supplied nodes, with the instrumentation and measurement of
simple applications to illustrate the concepts presented.
Attendees are expected to have knowledge of nesC/TinyOS programming.
The TinyOS 2.1 tutorial taking place immediately prior can provide
the necessary background if needed. The presenters will be Prabal
Dutta and Rodrigo Fonseca, the creators of iCount, Quanto, and Epic.
- Tutorial Session IV-1: Building the Internet of Everything Using the
TinyOS Kernel Interface (TOSKI)
by Chad Metcalf, Jonathan Hui and Alec Woo (ArchRock)
Time: April 16,2009 Thursday 1:00PM~3:00PM
Abstract:
In 2006, we demonstrated the first
complete and low power IPv6/6LoWPAN network stack for wireless
sensor networks (sensornets). Since then, IPv6 has had significant
impact in both academia and industry. In this tutorial, we will
provide faculty, students, and practitioners interested in embedded
networking with a hands-on understanding of the foundations of
IPv6/6LoWPAN and the practical application of the technology. We
will emphasize the use
of open standards at several levels - including TinyOS 2.x operating
system, IEEE 802.15.4 radio, 6LoWPAN adaptation, IPv6 networking,
UDP/TCP transport, and HTTP - as they apply to ubiquitous embedded
network devices and applications.
This tutorial will present: (i)the benefits of an IP-based
architecture for sensornets, (ii)a technical overview of IP-based
networking extended to sensornets using 6LoWPAN, and (iii) hand-on
experience building IP-based applications using a
production-quality, TinyOS-based network kernel (TOSKI) on
EPIC-based modules.
Please join us if you want to make your sensor network applications
run native IP and become part of the Internet!
Requisites: For the hands-on session, a bootable CD drive is
required. If you are unfamiliar with TinyOS/nesC, we encourage you
to attend the TinyOS 2.1 tutorial during the morning session.
Knowledge of IP networking and BSD sockets is helpful but not
required.
- Tutorial Session IV-2: IP-based Sensor Networks: a Hands-on Tutorial (uIP)
by Adam Dunkels (Swedish Institute of Computer Science)
Time: April 16, 2009 Thursday 3:00PM~5:00PM
Abstract: IP-based sensor networks are a rapidly
emerging hot topic in both academia and the industry.
The open source uIP stack from the Contiki operating system, first
released in 2001, is used in IP-enabled products and systems from
hundreds of companies, ranging from pico-satellites, airplanes, and
car engines, to worldwide freighter container tracking systems, ship
control systems, and oil boring and pipeline monitoring systems. In
October 2008 Cisco Systems released uIPv6, the world's smallest
fully compliant IPv6 stack, for Contiki.
During this tutorial, participants will get started with building
IP-based sensor networks with Contiki and uIP, and get hands-on
experience with developing, compiling, and running IP-based software
on sensornet hardware, setting up IP networking to the sensor
network, and getting performance metrics (power, throughput,
latency) from a running network.
We use a combination of Tmote Sky and Sentilla JCreate motes as the
hardware platform. We provide Tmote Skys and JCreates for
participants to borrow during the tutorial.
To avoid installation of compilers and tools, participants will use
the Instant Contiki development environment, a complete development
environment in a single-file download consisting of a VMWare virtual
machine with all Contiki software development tools installed:
