In this paper, the authors have developed a fault tolerant technique to improve reliability in mobile grid environment. The proposed technique handles both resource and network failure and present recovery techniques also. When the job is assigned to the node, acknowledgement must reach monitoring agent within certain time interval else it results in some resource failure. Hence cluster head try to schedule job to any other node from the same cluster or cluster head will reschedule the job through master server. When executed job does not reach cluster heads after specified time interval it results in network failure.
