Problem statement: In order to achieve high level of reliability and availability, the grid infrastructure should be fault tolerant. Since the failure of resources affects job execution fatally, fault tolerance service is essential to satisfy QoS requirement in grid computing with respect to mobile nodes. Approach: We propose a fault tolerant technique for improving reliability in mobile grid environment considering the node mobility. The Cluster head and monitoring agent was designed in such a way it addresses both resource and network failure and present recovery techniques for overcoming the faults. Results: The proposed model achieves a identifiable performance when compared to the previous model (HRAA). By simulation results, we analyze the node and link failures on parameters such as delivery ratio, throughput and delay against the rate of success. Conclusion: The proposed fault tolerant approach checks for availability of the nodes with least work load for transferring the executed job to cluster head providing an alternate path in case of failure thereby enhancing the reliability of the grid environment.
