About avroraZ
Posted on September 29th, 2008 by Rodo
AvroraZ, a research project of the AWS center, is an extension of the Avrora emulator – The AVR Simulation and Analysis Framework – which allows the emulation of the Atmel AVR microcontroller based sensor node platforms with IEEE 802.15.4 compliant radio chips thus allowing emulation of sensor nodes such as Crossbow’s MicaZ
Avrora is a set of simulation and analysis tools for programs written for the AVR microcontroller produced by Atmel and the Mica2 sensor nodes. Avrora contains a flexible framework for simulating and analyzing assembly programs, providing a clean Java API and infrastructure for experimentation, profiling, and analysis.
AvroraZ is based on design, implementation and verification of several extensions to Avrora: the address recognition algorithm, an indoor radio model, the clear channel assessment (CCA) and link quality indicator (LQI) of the IEEE 802.15.4 standard. The motivation of this implementation is to enable precise emulation of IEEE 802.15.4 based protocols without any modifications in the code developed for the real hardware.
The tool is being tested and evaluated using the implementation of beacon-enabled mode of the IEEE 802.15.4 protocol stack developed in nesC, under the TinyOS operating system for the CrossBow MICAz motes called Open-zb as well as new add-ons to this implementation that allow mesh topology.
