 About WSN Test Bed:

WSN Test Bed at MAJU comprises of Sun SPOT sensor nodes. Sun SPOTs (Sun Small Programmable Object Technology) are small, wireless, battery-powered devices developed at Sun Labs to explore the next frontier of network computing. These devices can be used in a wide range of applications including robotics, environmental monitoring, asset tracking, proactive health care and many others. Sun SPOTs are powered by a specially designed small-footprint Java virtual machine, called Squawk, that can host multiple applications concurrently, and requires no underlying operating system. Stackable boards include application-specific sensors and actuators such as accelerometers, light detectors, temperature sensors, LEDs, push buttons and general I/O pins. The devices can be duty cycled to run for months on a single charge of their rechargeable battery.

With current state-of-the-art, developing applications for most other embedded devices is a tedious chore -- often involving learning unfamiliar languages/tools with little or no debugging support. By supporting application development and debugging via standard IDEs such as NetBeans, our platform opens up the exciting world of embedded programming to a much broader class of developers. Sun SPOTs have been commercially available at sunspotworld.com since March 2007 and have been used in several high profile technology demonstrations with Sun customers and partners, at university courses and even art installations. They are also proving to be a popular platform for hobbyists and researchers. Sun SPOTs have been featured on Infoworld's list of Must-have gadgets and Javalobby's list ofAmazing Java Applications. Click on the video presentation link in the right column to learn more about Sun SPOTs.

The Sun SPOT Software Development Kit (SDK) includes the necessary documentation, code samples and software to help you develop applications for SPOTs. The SDK also includes an emulator so users that do not have any Sun SPOT devices can still develop and run applications on virtual SPOTs. All of the Sun SPOT SDK (and even the hardware) is available as open source from Java.net.
