This paper addresses the workflow rescheduling problem in the Grid where resource performance is fluctuating and hard to predict. Unlike existing rescheduling approaches targeting the same problem, the proposed a mobile agent based distributed approach. Once a workflow is submitted to a central workflow scheduler, an initial schedule for tasks in that workflow will be created first. Then, at the workflow run-time, mobile agents which carry those tasks will reschedule themselves by a rescheduling algorithm when resource performance changes.
