An Effective Approach for Improving Responsiveness of Total Bandwidth Server
As a result of increasing in diversity and complexity, real-time embedded systems have to deal with both periodic and aperiodic tasks. In such systems, it is expected that response time of aperiodic tasks is as short as possible. Total Bandwidth Server (TBS) is one of effective task scheduling algorithms for a mixture of periodic and aperiodic tasks. As a successor to TBS, Adaptive TBS (ATBS) is an algorithm where TBS is enhanced with prediction of execution times. Virtual release advancing (VRA) is an additional technique for TBS to shorten response time of tasks and Enhanced VRA (EVRA) is the extended version of VRA with lightweight complexity. In this paper, combination of ATBS and EVRA is examined to further improve the responsiveness of TBS. Simulation results show that the combination can reduce response times by up to 25% compared with TBS under heavy loads, while maintaining the schedulability and relatively low time complexity of the system.
It was my honor to be presented and introduced about my research's results at the 8th International Conference on Information and Communication Technology for Embedded Systems (IC-ICTES 2017) in Thailand. I presented an academic paper on combination of the adaptive TBS and the (enhanced) virtual release advancing for real-time task scheduling. Significantly, my paper was selected as one of the Best Paper Awards of the IC-ICTES 2017. Fist of all, I would like to thank Associate Professor Tanaka as my supervisor for his devoted helps during my conducting research and supporting me to present at the conference. Then, I would like to express my thanks to JAIST for the opportunity to continue conducting my doctoral research. Finally, I have to thank JAIST officers who helpfully supported me during official procedures, especially one of the conference. All of these supports are really helpful and motives to my future research at JAIST.
