Crossbow has offered the Stargate gateway and Xscale CPU platform for
approximately 1.5 years. In this time, the Stargate has found a wide range
of applications. Crossbow will review these applications. In addition to
selling as a standalone item, Crossbow has developed a number of software
utilities that run on the Stargate for managing sensor networks. Crossbow
will review these tools and present how the Stargate is an effective sensor

Server is a small, mobile device that is designed to be a user’s wireless repository for their
mobile media, documents, preferences, and other personal information. Built
around the Stargate platform it takes advantage of the
trend in high density mobile storage and short range wireless standards.
Initial Personal Server prototypes have paved the way for commercial
adoption of basic media-access technology, highlighting the power of personal
mobile systems that are small enough to be easily carried in the pocket and
conveniently accessed over a wireless link. In addition to storing movies,
music, and photographs, the Personal Server has also been used as the center of
personal medical data in the CareLog
application, as well as the basis for interaction with smart
spaces using RFID. From a research perspective, the Personal Server
highlights how the emerging technologies embodied in the Stargate platform can
be integrated into personal mobile devices.
Bio: Dr. Want is a principal engineer at Intel Research, where he has managed the Ubiquity project since 2001. He received his B.A. degree in computer science from Churchill College, Cambridge University, UK, in 1983 and continued research at Cambridge into reliable distributed multimedia systems. He earned a Ph.D. degree from Cambridge in 1988 and then joined Olivetti Research in 1988. While there, he developed the Active Badge, a system for automatically locating people in a building. Dr. Want later joined the Ubiquitous Computing program at Xerox PARC in 1991 and led a project called PARCTab, one of the first context-aware computer systems. At PARC, he managed the Embedded Systems group and earned the position of principal scientist.

|This discussion involves the development hurdles and challenges posed when integrating the Stargate
into an advanced surveillance robot platform. The LRV (Lightweight Reconnaissance Vehicle) can climb
stairs, navigate through snow, and fit below vehicles for inspection. The Stargate is stretched by
this robot to real-time video streaming, 2-way stereo audio, and an interface to several BrainStem
processors that handle motion control and I/O functions on the robot. The discussion will center
around the development of the Acroname Daughter Board which manages many of these features including
a USB hub, audio Codecs, video capture and streaming, and several other key functions of the system.
The challenges include mechanical, electrical, and software interfaces in the robotics domain.
Acroname has been involved in the Stargate development for several years working with Intel on design issues for the Stayton and Stargate processors. The commercially available Stargate is distributed by Acroname to robotics researchers and the platform is also used in contract design work Acroname is involved in.
|The Intel Mote platforms are motivated by several design goals:
increased CPU performance, improved radio bandwidth and reliability, and the usage of commercial
off-the-shelf components in order to maintain cost-effectiveness. The first generation is built
around an integrated wireless microcontroller consisting of an ARM7 core, a Bluetooth radio, RAM
and FLASH memory, as well as various I/O options. The software architecture is based on an ARM
port of TinyOS. Networking and routing layers have been created on top of the TinyOS base to
provide the underlying multi-hop functionality. The network is self-organizing on startup and
has mechanisms to repair failed links and circumvent failed nodes. The second generation Intel
mote has a common core to the next generation Stargate2 platform, and is built around a new
low power X-Scale processor and an 802.15.4 radio. The processor has a rich set of interfaces
that ease the sensor integration, larger RAM and CPU power to support data processing and larger
FLASH to enable extended offline logging.
The Intel Mote was deployed in multiple pilot industrial applications. In this talk, we describe the equipment monitoring application using industrial vibration sensors. This application was chosen since it benefits from the increased platform capabilities and network bandwidth of the Intel Mote platform. We will also describe a water pipeline monitoring application, deployed in Boston last year.
Bio: Lama is currently a senior researcher at Intel Corporation. She is working on creating the next generation of self-organizing wireless sensor network nodes (also called "motes"). Lama has over 8 years of experience in the areas of computer architecture, embedded platforms, networking and wireless sensor networks. Previous assignments at Intel involved the development and evaluation of microarchitecture components for the Itanium® and Itanium® 2 processors. Prior to joining Intel, Lama has held multiple senior roles at Ubicom Inc, Weave Innovations and Microsoft Corporation. Lama received her MS and BS in computer engineering at the University of Wisconsin-Madison. Her research focused on computer architecture and design validation.
|Project ExScal (for Extreme Scale) designed, developed, and deployed the
largest wireless sensor network to date. The system was used to detect,
classify, and track intruders in real time across an extended area (1km by
300m). To span this area, ExScal included a backbone ad hoc network of
802.11 nodes on a hitherto unprecedented scale. We adopted the Stargate
platform for the backbone tier to serve as the basis for developing
efficient, robust, and easily deployable backbone service. Stargate's
Linux-based open source system software and the portability of EmStar
framework facilitated our software design and development. In this talk,
we focus on the ad hoc 802.11 backbone of ExScal and detail the design and
performance of one of its three routing protocols.

|PlatformX is an open-source suite of development tools designed to support various Stargate-related
platforms and applications. Hosted on Sourceforge, it is designed to allow individual contributors
to maintain local versions of a Stargate software build, configured for their specific needs, while
still tracking a central system base. Additionally, the system is designed to encourage community
participation, by allowing people to generate and submit patches to the build process, enabling the
core system to be used for a wide variety of purposes. This tutorial will cover the basic development
tools, showing how they can be used to update and configure a Stargate platform.

|Many Wireless Sensor Network (WSN) applications are composed of a mixture of deployed devices with varying capabilities, from extremely constrained 8-bit "Motes" to less resource-constrained 32-bit Stargates. The development and deployment of WSNs rides heavily on the availability of simulation, emulation, visualization and analysis support. EmStar is a software environment for developing and deploying complex WSN applications on networks of 32-bit embedded microserver platforms, and integrating with networks of Motes. EmStar consists of libraries that implement message-passing IPC primitives, tools that support simulation, emulation, and visualization of live systems, both real and simulated, and services that support networking, sensing, and time synchronization.|
