Task execution reliability of resource allocation with tasks replication in mobile ad hoc grid

This paper reviews task execution reliability in mobile ad hoc grid. We consider resource allocation for mobile ad hoc grids with centralized architecture in the presence of dependent tasks. Allocating appropriate resources for the tasks can avoid uncompleted tasks and ensure the service reliability. With the aim to increase service reliability, resource management can assign the same tasks to different resources for parallel execution (tasks replication). Analytical example is given to illustrate the reliability. The result reveals that assigning the same tasks to more than one resource nodes has increased the reliability. Assigning the same tasks to 4 or 3 resource nodes provides superior reliability than that of just 2 resource nodes.
