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.

A low cost error-based program testing apparatus and method are provided. The testing apparatus according to an embodiment of the present invention generates error programs by adding errors to a test target program, selects a test target error program associated with test data among the error programs using error information obtained through the error addition, receives the test data to execute the test target error program, and tests for presence/absence of the errors. Accordingly, it is possible to reduce a text execution time and testing costs.
