Tython

A Dynamic Simulation Environment for Sensor Networks

Michael Demmer and Phil Levis

Overview

Tython is an environment for testing and analyzing sensor network applications. Tython is itself not a program simulator -- it uses TOSSIM to model TinyOS execution.

Tython compliments TOSSIM executions by adding a full featured scripting environment to augment the simulation. This allows users to build on top of and extend Tython to meet application specific requirements. This also significantly helps the debugging process, allowing an arbitrarily complicated experiment to be repeatedly executed on successive versions of the code.

Tython also includes flexible environmental models to accommodate a wide range of applications and real world scenarios. Users can thereby include in their program simulations a wide range of models for environmental effects. Furthermore, the Tython implementation is extensible, allowing developers to augment the included models with specific ones relevant for a particular application.

Tython is distributed as part of TinyOS.
