with peripherals such as radios, analog-to-digital converters (ADCs), memory devices, and sensors. The periods of busy-waiting waste time and energy which are both limited resources for many mote applications. This document presents techniques of using software thread integration (STI) in TinyOS applications to reclaim the idle time and use it for useful processing. The TinyOS scheduler is modified to support the selection and execution of integrated threads and analyzes the impact of integration on task response time. A microphone array sampling application is used to demonstrate the savings. Integrated tasks in the sample application finish 17.7% faster and the application?s active time is reduced by 6.3%.
