11 TinyOS TinyOS is a small micro-threading operating system that abstracts core application development from specific hardware details The design methodology is to 'wire' different components to each other – higher level components call 'tasks' in lower level components, and lower levels signal 'events' to higher levels

12 TinyOS

13 Sleep Mode – Power Conservation Query Mode – Data Acquisition Re-Programming Mode – Future Option Modes of Operation

14 –Environmental Conditions -20 – 80º C 0 – 100% Relative Humidity (RH) –Sensor Accuracy Light Sensor: ±10% Lumens Humidity: ±3% RH Temperature: ±3º C –Power Usage 3.3V Operating Voltage Goal: 6 Month Battery Life Specifications

15 –Server Pentium-class PC or better NT-based OS Internet Connectivity Serial Port MySQL Database Apache / PHP Webserver –Mote Development Chipcon CC1010 Development Kit Keil uVision2 Integrated Devel. Environment (IDE) Low-Power Sensor Hardware Equipment

16 –Hardware Selected most of the components Preliminary designs –Software: TinyOS Analysis of TinyOS 1.0.0 source code (nesC) Began port to CC1010 hardware Working on simple Blink application Project Progress

17 –Software: WiseDB Using MySQL++ API –Analyzed code utilizing MySQL++ –Performed database operations Implementing Serial Communications –Using Serial API written by Ramon Klein –Tested with loop-back (null-modem) connection –Wrote basic simulator of gateway mote Project Progress

18 –December 2002 Project Research Preliminary Design Proof-of-Concept Porting TinyOS to CC1010 –January 2003 WiseDB Interfaced to Hardware Hardware Design & Software Driver Development Continue Porting TinyOS to CC1010 –February 2003 Add Scheduling / Routing to WiseDB Finalize Hardware (Design PCB) Project Timeline

19 –March 2003 Finalize WiseDB Complete Port of TinyOS to CC1010 –Integrate Hardware Drivers –Implement Advanced Power-Saving –Implement Routing System-Wide Testing and Debugging –April / May 2003 Continued System Testing / Debugging Web-Interface Final Presentation and Report Project Timeline
