What is Avrora?

Avrora is a cycle-accurate simulator for sensor network programs. The MicaZ and Mica2 platforms are supported. The main Avrora web page contains a lot of good information but is not actively maintained; Avrora development has moved to Sourceforge.

Installing Avrora

Avrora works fine on Linux and Windows. The main prerequisite is a Java 5 or 6 development environment. Download the latest CVS snapshot: 

cvs -d:pserver:anonymous@avrora.cvs.sourceforge.net:/cvsroot/avrora login
cvs -z3 -d:pserver:anonymous@avrora.cvs.sourceforge.net:/cvsroot/avrora co -P avrora

The following will assume that you have set $AVRORA to be the absolute path to this avrora directory.

Build Avrora: 

cd $AVRORA
make avrora

There should not be any error messages.

Add $AVRORA/bin to your CLASSPATH. Ensure that you can run Avrora: 

java avrora.Main

The output should be a bunch of usage information. On Cygwin the colors may not show up properly in which case you'll want to invoke Avrora using the -colors=false command line option.

Simulating TinyOS Applications

It is assumed that you have TinyOS 2.x installed and can build applications. Try these commands: 

cd $TOSROOT/apps/Blink
make micaz
mv build/micaz/main.exe Blink.elf
java avrora.Main -platform=micaz -simulation=sensor-network -seconds=3 -monitors=leds Blink.elf

The output should be something like this: 

Avrora [Beta 1.7.107] - (c) 2003-2007 UCLA Compilers Group

Loading Blink.elf...[OK: 0.068 seconds]
