移动Agent为完成用户指定的任务 ,通常需要移动到多个主机上 迁移策略为移动Agent规划出最佳迁移路径 ,保证移动Agent正确、高效地完成任务 提出了“旅行图”的概念并给出了基于“旅行图”的 3种迁移策略 旅行图能描述移动Agent的移动语义并能刻画运行环境的动态变化 载有“旅行图”的移动Agent感知运行环境的变化 ,及时反应并自主修改迁移路线 ,按照预先设定的指标完成任务 ,充分体现了Agent的反应性和自主性 基于“旅行图”的迁移策略还可避免由网络断连或结点失效导致的迁移失败 Mobile Agent usually needs to migrate to multiple hosts to complete the task specified by the user Migration strategy for mobile Agent Planning the best migration path to ensure that Mobile Agent correctly and efficiently complete the task Proposed the concept of “travel map” and given Based on the “travel map”, three kinds of migration strategy maps can describe the mobile semantics of mobile agent and characterize the dynamic changes of the operating environment. Mobile Agent with “travel map” perceives the changes of the operating environment, promptly responds and autonomously revises the migration route, According to the pre-set indicators to complete the task, fully reflects the reactivity and autonomy of Agent Based on the “travel map” of the migration strategy can also be avoided by the network disconnection or node failure caused migration failure
