  3. Summary WISENET is a network of low-power wireless sensor devices (“motes”) designed to record and report environmental data. (MICA mote from Crossbow Technology)

  4. Standards Hypertext Transfer Protocol (HTTP) Structured Query Language (SQL) Serial Link (RS-232) Micro-Controller Serial Link (I2C) FCC regulations (ISM Bands)

  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
