Abstract

In grid systems, as the number of heterogeneous components increases in the networks, the chance of failure of resources increases. Identifying the various faults that occurs and imparting tolerance to those faults has become the principal area of concern. Many of the existing fault tolerant algorithms concentrate on increasing throughput and reducing the response time but consider less on increasing user satisfaction. The proposed fault-tolerant check-pointing based Deadline Hit Count (DHC) scheduling algorithm concentrates on increasing the efficiency of the resource through identifying the faults and reducing the turn-around time. It also increases the user satisfaction as it combines both the dynamic check pointing approach and fault tolerant scheduling. In the proposed technique, a DHC scheduling algorithm with check-pointing is implemented to identify and pro-actively tolerate faults to select the appropriate resources. Experiments are performed to assess the performance of the proposed approach using GridSim tool and have shown better performance.
