【摘要】 面向普适计算的中间件是信息技术领域一个非常重要的研究方向。本文提出了一个轻量级的基于构件化的Agent中间件系统-SkyWalker。它基于.NETFramework环境,支持构件级重构、Agent动态迁移、跨平台等特点。文章接着论述了SkyWalker的结构模型以及构件动态重构与迁移和服务动态发现与加载的算法步骤。最后在两个不同平台上进行了性能测试和分析,证明了SkyWalker在代码尺寸、功能和性能上是有较好的优势。更多还原

【Abstract】 Middleware for pervasive computing is a very important research area in information technology. The SkyWalker, a lightweight component-based agent middleware is proposed, The mobile agent is composed of components and each component can change its behavior and be replaced according the volatile agent environment. It’s base on the .NET Framework and supports component reconfiguration, agent mobility, cross-platform. Next, the architecture model of SkyWalker and the algorithms of agent reconfiguration,agent mobility, service discovery and loading are analyzed. Finally, the performance tests in two different platforms are given to evaluate the work, and the test proved the advantage of SkyWalker on size, function and performance.更多还原
