Users increasingly want to use Internet applications for information access and processing from a variety of fixed and mobile networked computing devices, such as desktops, cell phones, and PDAs. These devices have different capabilities, are not equally secure, and operate under different network conditions. Mobile users may also want to transfer an on-going communication activity from one device (e.g., a desktop) to a different device (e.g., a PDA). The proposed research aims to design a software framework for building distributedapplications to meet these emerging needs. A key concept is to use mobile, context-aware communicating components to compose distributed applications. Using component mobility across devices, system designers can build robust and responsive applications that adapt to varying network connectivity and to various device capabilities. The framework will also allow applications to adapt to changes by dynamically adding and removing components, or by replacing a set of components with another set. To allow users to move active work across devices, communication among components will handle component mobility and tolerate transient disconnections. This research will address performance issues, develop software methodology to accommodate device heterogeneity, and explore solutions to handling security concerns in using the framework to build distributed applications.

用户越来越希望使用因特网应用程序来从各种固定和移动的联网计算设备（诸如台式机、蜂窝电话和PDA）进行信息访问和处理。这些设备具有不同的功能，安全性不同，并且在不同的网络条件下运行。 移动的用户还可能希望从一个设备（例如，桌面）到不同的设备（例如，PDA）。拟议的研究旨在设计一个软件框架，用于构建分布式应用程序，以满足这些新兴的需求。一个关键的概念是使用移动的，上下文感知的通信组件组成分布式应用程序。 利用跨设备的组件移动性，系统设计人员可以构建健壮且响应迅速的应用程序，以适应不同的网络连接和各种设备功能。该框架还将允许应用程序通过动态添加和删除组件，或通过用另一组组件替换一组组件来适应变化。为了允许用户跨设备移动活动工作，组件之间的通信将处理组件移动性并容忍暂时断开。 这项研究将解决性能问题，开发软件方法，以适应设备的异质性，并探讨解决方案，以处理安全问题，使用框架来构建分布式应用程序。
