摘要： IETF的移动IP协议存在代理的部署少、三角路由增加网络开销以及操作系统的支持有限等问题，未得到广泛应用。该文针对移动IP协议的不足，提出了一个新型的嵌入式移动性支持方案。该方案引入嵌入式移动代理和地址索引服务器来实现移动管理，最大限度地减小了移动管理对网络基础设施的依赖，为单个或成组移动设备提供了透明的移动服务。仿真实验表明，该移动性方案开销小、效率高，易于实现。

Abstract: Mobile IP has problems such as lack of agents, triangle routing and limitation of the support of the operating system. Therefore, mobile IP has not been put into widespread use. This paper proposes a novel mobility support scheme based on embedded technology. The scheme realizes the mobile management with embedded mobile agent and address trail server, reduces the dependence on the network infrastructure and provides the transparent mobile service for mobile equipments. Simulation study shows that this mobility scheme costs little, has high efficiency and is easy to realize.

Key words: embedded system, mobile management, mobile agent, mobility
