CS321 -- Warmup Project

Warmup Project:

This assignment is intended to introduce you to programming sensor networks using the TinyOS operating system. You will need the following software tools and hardware (we will provide):

TinyOS-1.x operating system to program sensor networks (detailed installation instructions for Windows can be found here)
java to program PC applications (java toolchain installation instructions can be found here)
2 iMote2 motes (IPR2400)
sensorboard (ITS400)
interface board (IIB2400)

This assignment has two parts: you will learn to build a simple application, access data from sensors and use timers in the first part, and setup basic networking, interface to a PC, and process sensor data on the PC, in the second part. We provide the source code.

Basic AntiTheft application:

Goal: Write a really simple anti-theft application which can protect our motes from being stolen.

Tasks:

Detecting theft

Assume: thieves put the motes in their pockets. So, a “dark” mote is a stolen mote.
Theft detection algorithm: every N ms check if light sensor is below some threshold.

Reporting theft

Assume: bright flashing lights deter thieves.
Theft reporting algorithm: light the red LED for a little while!

You will see: Basic components, interfaces, wiring, essential system interfaces for startup, timing, sensor sampling.

Usage: Unzip AntiTheft.zip file to your home directory and read readme1

Advanced AntiTheft application:

Goal: Different anti-theft mechanisms may be appropriate for different times or places. Our perfect anti-theft system must be configurable! We also need to have a backup plan if the bright LED does not deter the thief: report the theft to a PC.

Assume: a base station (dedicated mote) is connected to a PC via USB cable and the PC is running our java application.

Tasks:

Reconfigurability

Some settings, such as light level threshold or frequency of the theft detection algorithm can be changed and updated on the motes from the java application.

Advanced theft reporting

The stolen mote will broadcast a theft message. Consequently, an alert message with the ID of the mote will be shown on a PC screen.

You will see: How to use basic networking, how to start (and stop) services, “external” types, and their use in networking, how to receive and parse tinyos messages on a PC (using IIB2400 interface board).

Usage: Unzip AntiTheft.zip file to your home directory and read readme2

This application is a courtesy of David Gay, but was modified to tinyos-1.x and simplified for the purposes of CS321 class.
