摘　　要：为了更好地利用普适计算环境中的计算资源、减少人为干预、提高工作效率,提出了应用的follow-me迁移需求,即计算可以随着用户的移动在异构设备和计算环境中移动,让移动中的用户能够体验到不间断的计算。提出了基于移动代理的普适计算中间件FollowMeAgent。结合情境感知技术,利用软件代理所具备的移动性实现应用的自主迁移,并根据应用特点对迁移策略进行了细分。在此平台上开发了若干应用,通过性能测试证明其可行性和有效性。A new requirement of application follow-me mobility was advanced to make better use of pervasive computing resources, reduce human intervention and thereby improve work efficiency. Namely, application should follow mobile users when they change to a different environment, in order to let them enjoy uninterrupted computing experience. A mobile; agent based pervasive computing middleware FollowMeAgent was proposed to enable application follow-me migration. By leveraging context-awareness techniques, application was capable of migrating autonomously. Migration strategies were refined according to the characteristics of different applications. On top of FollowMeAgent middleware, some applications were implemented and performance was evaluated.
