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.

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.


A low-power, mote-scale Pulsed Doppler Radar sensor board. The Samraksh Company's first offering in a suite of Wireless Sensor Network products.

Comes with the BumbleBee Software Package: device drivers, data collection modules and sample applications for download.

For more information about the BumbleBee, see the Learning page.

Key features:

  • Operates at a 5.8GHz center frequency
  • Coherent quadrature output (both I & Q)
  • Maximum detection range of 10m
  • Maximum range controllable via software down to 1m with range gate sharpness of 0.2m
  • On-board (internal) antenna with 60 degree conical coverage pattern
  • Optimized for human-like targets
  • Responds to radial velocities between 2.6cm/s and 2.6m/s
  • Easily interfaced with mote devices
  • Ships with battery pack and with cabling for use with the .NOW mote
  • Connector boards / do-it-yourself instructions available for interfacing with IRIS/MICAz and Imote2 motes

The BumbleBee Radar enables a number of low-power, wireless sensor network applications including simple motion detection, robust intrusion detection using velocity estimation, velocity-based motion tracking and vibration monitoring.
