支持移动计算的反射式中间件

Reflective Middleware For Mobile Computing

传统中间件基于黑盒的设计思想，缺乏必要的灵活性，无法适应复杂动态多变的移动计算环境。反射技术可以使应用程序在运行时检查中间件所提供的服务类型，动态的构造调用请求，适应变化的环境。文章研究了反射的相关概念，中间件技术，分析了移动计算的实际需求，提出了一个支持移动计算的反射中间件架构，支持环境感知、异步通信、动态重配置等。

As a result of ＂black box＂ design structure, traditional object-oriented middleware is short of the necessary flexibility and adaptability, can not satisfy the need of mobile computing. With reflective technology, mobile applications can check the types of service that middleware provide at run time, and build request-transfer dynamically. The paper studies the reflective middleware, analyzes the requirements of mobile computing, and proposes a model of reflective middleware which supports context-aware, asynchronous communication and dynamic reconfiguration.
