Grid computing serves as an important technology to facilitate distributed computation computational grids solve large scale scientific problems using heterogeneous geographically distributed resources. Problems like dispatching and scheduling of tasks are considered as major issues in computational grid environment. The Grid Scheduler must select proper resources for executing the tasks with less response time. There are various reasons such as network failure, overloaded resource conditions, or non-availability of required software components for execution failure. Thus, fault-tolerant systems should be able to identify and handle failures and support reliable execution in the presence of failures. Hence the integration of fault tolerance measures and communication time with scheduling gains much importance. In this study, a new fault tolerance based scheduling approach Fault Tolerant Min-Min (FTMM) for scheduling statically available meta tasks is proposed wherein failure rate and the fitness value are calculated. The performance of the fault tolerant scheduling policy is compared with min-min scheduling policy using GridSim and the results shows that the proposed policy performs better with less makespan in the presence of failures. The number of tasks successfully completed is also more when compared to the non-fault tolerant min-min scheduling policy. Thus the proposed FTMM algorithm not only achieves better hit rate but also improved makespan.
