Abstract: Disclosed herein are a location measurement method and apparatus. The apparatus includes a first grading unit, a first presumed line calculation unit, a second grading unit, a second presumed lined calculating unit, a presumed location calculation unit, and a final location calculation unit. The first grading unit determines the grade of a first RSSI. The first presumed line calculation unit calculates the range of the object from a first node based on the grade of the first RSSI. The second grading unit determines the grade of a second RSSI. The second presumed line calculating unit calculates the range of the object from a second node based on the grade of the second RSSI. The presumed location calculation unit calculates two presumed locations. The final location calculation unit determines one of the two presumed locations to be the final location of the object.

Abstract: Disclosed herein is an apparatus for continuous profiling for a multicore embedded system, the apparatus including a profiling data reception unit for receiving one or more pieces of profiling source data, in which events for each core in a multicore embedded system are written, from the multicore embedded system; a profiling data analysis unit for analyzing the profiling source data, determining a time at which each of events included in the profiling source data occurred and a core corresponding to the event, and determining whether each of the events is a past event depending on the time at which the event occurred; and a profiling file management unit for distinguishing each of the events depending on the determination of whether the event is a past event and storing the events in profiling files.

Abstract: Disclosed herein are a dynamic scheduling method for guaranteeing Quality of Service QoS depending on network transmission traffic and a system using the same. The dynamic scheduling method includes assigning communication channels to respective nodes based on Identifications (IDs) of parent nodes corresponding to the respective nodes, setting priorities for assignment of time slots to the respective nodes in each quarter based on data traffic volumes corresponding to the respective nodes, and assigning time slots to the respective nodes in each quarter depending on the set priorities for assignment of the time slots.
