Exploring m-Platform for Local Application Performance: Sound Source Localization

In this report we present results of a performance study of the m-platform, a modular stack-based architecture for sensor nodes. An m-platform node consists of several boards or other hardware modules that have different performance properties, but share the same communication interfaces. The main motivation for a stack-based architecture is design flexibility and reconfiguration, and not necessarily least possible power or fastest system response. The report focuses on power minimization, and presents a power and timing aware task scheduling algorithm. We apply the algorithm to a sound source localization application.
