摘要： 针对传统Ad Hoc网络节点面临性能下降或动态离开而无法继续提供服务的情况，基于迁移服务模型提出一种移动Ad Hoc网络服务迁移机制。该机制采用上下文动态感知、迁移目标选择及移动代理等关键技术，保证服务的可持续性。实现基于Aglets的移动Ad Hoc网络服务迁移平台，并验证该服务迁移机制的有效性。

Abstract: In mobile Ad Hoc network, the rapidly changing node’s operating contexts leads to situations where a node currently providing a certain service becomes unsuitable for hosting that service any longer. Based on migratory service model, this paper presents a service migration mechanism which uses dynamic context-awareness, migration destination selection and mobile agent so as to keep providing service continuity. A service migration platform based on Aglets is implemented in mobile Ad Hoc network. Experiment verifies the feasibility of the platform.

Key words: mobile Ad Hoc network, service migration, mobile agent, context-awareness
