Real-time Concurrency Control Based QSR in Broadcast Environments
广播环境中的Q可串行化实时并发控制

Real-time Data broadcast is now a popular data dissemination technology in mobile computing systems. The consistency constraint of mobile real-time transactions in broadcast environments is studied. After QSR is proposed formally, the necessary and sufficient conditions QSR are presented. Next, the concurrency control protocol based on time stamp ordering for QSR is described. Finally,experimental results show a substantial performance improvement of the new protocol.
