Abstract
A new application area in which wireless sensor networks are applied requires the performance of more elaborated and complicated task and the completion of those tasks within a time limit. Until now, it is, however, insufficient to do research on the mechanism of handling interrupt based on real-time sensor operating systems which carefully consider the limitation of resources of sensor nodes and the property of tasks which is executed in a wireless sensor network area. In this paper, the requirements satisfying real-time in sensor operating systems are analyzed and based on this, a system is designed and implemented. In addition, the proposed mechanisms are confirmed by several verification methods, and the efficiency of the performance and the satisfaction of those requirements for real-time are verified by simulation.
