Efficient priority assignment policies for distributed real-time database systems
Hong-Ren Chen, Y.H. Chin · 2007
Abstract: A lot of research works have been done in this filed of real-time database systems to seek for optimizing transaction scheduling. The findings of such studies examining the use of various algorithms of priority assignment policy have been discussed widely. One drawback of these approaches is presenting poor performance due to neglect repetitively missed real-time transactions. In this paper, an improved priority assignment policy named Flexible High Reward with concurrency control factor (FHR-CF) is proposed to reduce the MissRatio and WastedRatio. Key-word: priority assignment policy, real-time transaction scheduling, concurrency control factor, real-time database systems 1
