Abstract

Abstract: The traditional heterogeneous distributed real-time scheduling algorithm didn't give consideration to the dynamic behavior of tasks. An aperiodic non-preemptible and heterogeneous distributed dynamic fault-tolerant model and presenting two fault-tolerant scheduling algorithms was proposed based on this model: DRFSA algorithm and DSFSA algorithm. DRFSA(Dynamic and Reliability-driven of hybrid with Fault-tolerant Scheduling Algorithm)algorithm is to improve the system reliability as the scheduling objective through the reasonable scheduling. DSFSA (Dynamic and Schedulability-driven of hybrid with Fault-tolerant Scheduling Algorithm) algorithm is to improve schedulability as the scheduling objective and tries to enhance the schedulability through less task execution time. Both algorithms can dispatch the dynamic real-time tasks in the heterogeneous system andsimultaneously can respond to the task demands as far as possible.
