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
