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)
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
Project Details To test the peripherals attached with the
board like :-• Radio• Serial• External Flash• ADC (Sensors connectivity)• LCD interface
Agenda Software Support Experiments performed Demo Conclusion Future work
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
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

Conclusion/Observations The following peripherals was tested
successfully:-• LEDs• Radio• Serial• External Flash• ADC Lines
ADC0 and ADC2 are interchanged
Future Work LCD interface to be tested Implement a sensor network protocol on
the mote to have a greater confidence
