Tuscarora Framework is now Open Source

Tuscarora is a framework for developing highly scalable and portable Network Patterns (NP) and applications. The Framework serves as the narrow waist of the system, decoupling the Application Layer and the Network Patterns from the underlying radio and hardware platform, enabling portability, scalability and extensibility. Tuscarora was partly funded by DARPA.

The source has been released on GitHub at https://github.com/Samraksh/Tuscarora/. Learn More.

About Samraksh

Wireless Sensor Network Expertise We are experts in low-power, reliable wireless sensor networks (WSN) with world-class experience and deep, innovative research into the hardware, software and algorithmic issues they present. We design, manufacture and sell inexpensive high-performance, low-power, scalable and easy-to-program components and systems.

WSN-Enabling Products Besides the eMote .NOW and the BumbleBee highlighted below, we also provide a range of other sensors and supporting items. Complete network solutions can be deployed using these components.

eMote .Now: Low-power, High-performance, Network-ready, Easy-to-use Mote

Features High performance with low power modes for long battery life • Built-in networking with on-board radio and CSMA protocols over 802.15.4 • Program in C# using Microsoft's Visual Studio • Real time processing for time-critical applications • Sample apps for quick start-up

Software eMote: Micro Framework with real-time extensions • Libraries for networking, security and analysis • Virtual machine based app model

Hardware .NOW: 802.15.4 radio; options for external SMA or on-board antenna • High-speed NAND flash for near-line storage • Multi channel, multi-module 12 bit ADC • Micro SD card reader/writer • Serial over USB connector • 4 character LCD • Screw terminals for GPIO, ADC power etc • JTAG connector for developer use •Mezzanine connectors for extended access to I/O

BumbleBee: Versatile, Mote-Scale Doppler Radar

Features Micro-power pulsed Doppler radar with complex output • Complete package; no other components necessary for use • Ready-to-use sample applications for Arduino and eMote .NOW • Accurate displacement differentiation: fewer false alarms than PIR • Low power: run continuously for 8 days on AA batteries • Complex output enables many applications: intrusion detection, radial velocity and direction, acceleration, micro Doppler displacements, target categorization (human or car? or, pedestrian or cyclist?); and others
