Description
Summary:TinyOS is the current state of the art in operating systems for sensor network research. Event- based programming model of TinyOS presents concept of Task to allow postponing processing. For little processing and memory overhead and to avoid race conditions, tasks are non-preemptive. This causes executing long running task reduce system responsiveness. In general two approaches suggested for solving this problem: cooperative and multithreaded multitasking. In this paper we propose a new TinyOS task scheduler to integrate these approaches with new type of tasks. We argue that this approach improves the overall system responsiveness without concerning about data races or complicate programming for developers.
