    Abstract

    In a multi-organization environment like the GRID, each institute
    might want to apply some boundaries on how its resources are being
    utilized by other institutes. A disagreement between the multi-Virtual
    Organizations (VOs) might happen in the security aspect for the
    policy framework. Mobile Grid Services has given the ability to move
    jobs, data and application software from nodes to nodes during jobs’
    execution in the grid environment. It has also solved some of the
    lack in finding suitable resources for the jobs. To facilitate the ability
    to support mobile resource sharing between multiple heterogeneous
    VOs, an authorization policy management framework is needed
    to support authorization for heterogeneous authorization systems.
    Traditional authorization policy management frameworks act well in
    authorization policy for a single VO where the contributing hosts grant
    the permission to follow a global authorization system. However most
    of policy management tools do not provide a clear support for sharing
    mobile resources between multiple heterogeneous VOs. To solve this
    problem, we present a dynamic and heterogeneous policy management
    framework that can give a clear policy definition about the ability to
    move jobs, data and application software from nodes to nodes during
    jobs’ execution in the grid environment. We introduce an architecture
    for policy based resource management in the case of mobile sharing,
    and a scenario that explain the advantages of mobility mechanism and
    the role of policy in the grid systems. To check the performance of this
    architecture, a set of experiments had conducted. The results, analysis
    and the overheads estimation are presented in this journal.
