Desktop Grid resources are volatile, heterogeneous and geographically distributed in nature, so scheduling and fault tolerance become the important challenges for Desktop grid systems. In this paper a proactive fault tolerant strategy is developed which also considers the unwanted delays in association with speed and load of resources in the Grid while scheduling jobs on Grid resources. Simulation experiments are conducted by using GridSim toolkit 5.2. The experimental results obtained from applying the proposed strategy considerably improves the performance in terms of Throughput, Turnaround time & Success Rate.
