摘要：
Some work have been done in addressing real-time fault-tolerant scheduling algorithms. However, they all based on homogeneous distributed systems or multiprocessor systems, which have identical processors. This paper presents two fault-tolerant scheduling algorithms, RTFTNO and RTFTRC, for periodic real-time tasks in heterogeneous distributed systems. Reliability cost, a main performance metric, is applied. RTFTRC algorithm tries to minimize the reliability cost, while RTFTNO does not consider such metric. The results of the performance evaluation for two algorithms are discussed. Simulation experiments show that RTFTRC has better performance than RTFTNO.
