NODES PROJECT

A NOVEL DESIGN FOR EMBEDDED SENSOR NETWORKS

• Hardware - Software development for embedded systems
• Communication / networking protocols for sensor and ad-hoc networks
• File / Database management for sensor systems.

Our goal is to mobilize the latest in hardware technologies and software methodologies to create truly versatile sensor systems, for a multitude of applications. Our present research efforts are motivated by the requirements of  the Center for Conservation Biology at UCR .

The RISE (RIverside SEnsor) has been built as the prototype sensor platform demonstrating our current contributions

•  High performance,low power, state of the art platform
•  Built around the Chipcon CC1010 System on Chip
•  Incorporates TinyOS (ported to 80C51 CPU)
•  Gigabyte scale - High capacity flash data storage (SD-Card)
•  Multitude of sensors
  • Temperature
  • Carbon dioxide
  • Microphone
  • Camera
•  Integrated radio transceiver - Compatible with MICA for interoperability and investigation into the nature of heterogenous networks.

The Sense and Store paradigm is the central idea in our NODES project. Using this for data management and retrieval for sensor systems with large memories we have demonstrated significant gains over the prevalent Sense and Send methodology as shown in the following figure.

The figure shows the number of bytes transmitted in the SS (sense and send), SMS(sense merge and send), SSMS (sense store merge and send)  models using atmospheric data.
