  1. Testing and Verifiationof Kmoteusing Tiny OS Manish Aggarwal Guide :- Proff Purushottam K

  2. Kmote board: Front view LCD Interface JTAG Power Connector CC2420 Radio User and Reset button LEDs Expansion Line ADC lines Serial

  3. Kmote board: back view MicroController MSP430 Crystal 16MHz ST flash RS232 Trans-reciever

  4. Platform Details (Hardware) • Micro-Controller (MSP430) • Radio (CC2420) • Flash (STM25P80) • RS232 Trans-receiver (MAX3380) • 16MHz crystal for radio • LEDs • LCD interface (useful for debugging) • JTAG (to download the program) • ADC Lines (to attach sensors)

  5. Motivation • Number of motes available. • Not easily available and expensive for research and teaching purpose in India. • Goal: • To build knowledge base in sensor mote. • Aid easy availability in India. • Develop India specific applications. • To design a low cost, low power platform

  6. Project Details • To test the peripherals attached with the board like :- • Radio • Serial • External Flash • ADC (Sensors connectivity) • LCD interface

  7. Agenda • Software Support • Experiments performed • Demo • Conclusion • Future work

  8. Software support • Independent Programs (IAR workbench) • Use some existing OS • Tiny OS • SOS • Preferred approach • Use Tiny OS • Supports its close counterpart (Tmote) • Easy configurability • Good Documentation

  9. Tiny OS • Open source • Event driven architecture • Uses Components, Interfaces and wiring concept • Small memory footprint • Efficient in power and computation • Supports diverse application design

  10. Tiny OS programming

  11. Radio Component Send and Receive Packet Example

  12. Radio Component Serial Component Send and Receive Packet Example

  13. Radio Component Serial Component Send and Receive Packet Sense Data And send it Either on radio or serial Sensor Example

  14. Experiments Performed • BlinkTORadio • BaseStation (Radio to serial) • Block • BlinkConfig • TestAdc • SenseToSerial • SenseToRadio

  15. Conclusion/Observations • The following peripherals was tested successfully:- • LEDs • Radio • Serial • External Flash • ADC Lines • ADC0 and ADC2 are interchanged

  16. Future Work • LCD interface to be tested • Implement a sensor network protocol on the mote to have a greater confidence

  17. References • KMote - Design and Implementation of a Low Cost, Low Power Hardware Platform for Wireless Sensor Networks. Mtech thesis Report, N. Madabhushi • Tutorial on TinyOS2.0 from www.tinyos.net • Gay, D., Levis, P., and Culler, D. 2005. Software design patterns for TinyOS.

  18. Thank you • Demo • Any Questions??

  19. Tmote: Front

  20. Tmote: Back

  21. Difference between kmote and tmote • LCD Interface • Onboard sensor • Transreceiver

  22. Problems Faced • Make the platform work (Linux and windows) • Understanding Tiny OS • Downloading the program • Dump message packets to serial • Attach pot to check ADC

  23. Power Consumption
