PowerTOSSIM: Efficient Power Simulation for TinyOS Applications

Abstract:

Energy is a crucial constraint in wireless sensor networks. Because of the cost and difficulty of deploying a sensor network, it is imperative to be able to obtain the power profile of an application before deployment. We present PowerTOSSIM, a power modeling extension to TOSSIM, a TinyOS simulator. PowerTOSSIM accurately models power consumed by TinyOS applications. We also include a detailed model of the power consumption of the Mica2 motes.

News:

• 10/11/2005: Fixed installation instructions to reflect the fact that PowerTOSSIM is part of the released versions of TinyOS.
• 10/28/2004: Finally merged into main CVS branch. Updated instructions here.
• 08/27/2004: Integrating PowerTOSSIM into main TinyOS tree. It's on a branch in the main tree now. See here for instructions.
• 4/29/2004: Committed cpu cycle counting code. Usage instructions.

Detailed power model for the mica2.

TODO

• Add in CPU frequency fixes-TOSSIM is currently hardwired to 4Mhz, which is wrong for the mica2 (also bad design in general).
• Clean up CPU cycle counting code.
• Add support for the packet level radio model (soon)
• Write better processing/visualization tools
• Runtime support for querying info?
• Problems? Feature requests? Email me
