(Re)Enabling support for the CC2420 chip on the TinyOS Simulator

Simulation tools for networked devices are a valuable resource to speed up software development. • TOSSIM (TinyOS SIMulator)[1] is a network simulator that is part of TinyOS [2] (an operating system for networked wireless sensors). • The CC2420 chip [3] is a radio frequency transciever used in many wireless sensor devices. The TOSSIM maintained as part of the main TinyOS trunk does not implement simulation of the CC2420 chip. This has been succesfully implemented outside the primary TinyOS trunk in the past [4], however this support has not been maintained with newer versions of TinyOS. In this paper we describe in detail the process that was followed to add CC2420 simulation support to the latest TOSSIM. We also describe our evaluation method to confirm that the implementation is functional and accurate. We publish the results of our evaluations and show that the CC2420 is succesfully simulated within the TOSSIM environment.
