摘　　要：普适计算的目标是让环境和计算资源紧密结合,以便更好地为人类服务。为达到这一目标,移动设备和嵌入式设备构成了环境中计算资源的重要组成部分。然而,由于移动设备和嵌入式设备的计算资源有限,网络连接的多样性和不稳定性以及软硬件的异构性,开发用于这些设备的上下文感知应用复杂并且费时,其根本原因是缺乏一个统一的平台支持。为解决这一问题,我们提出了一种用于普适计算的轻量级中间件平台,叫做FollowMeLite。Fol-lowMeLite是整个FollowMe普适计算基础结构中的一部分。它构建在OSGi之上,集成了基于本体的上下文模型和基于工作流的应用模型以及用于适应多种网络连接的通讯服务。通过部署不同的组件模块,FollowMeLite可以方便的适用于多种应用环境。The goal of pervasive computing is to serve human being well by integrating environments and computational resources. To achieve the goal, mobile and embedded devices play an important role in pervasive computing. However, due to the limited resources, the diversity and unsteadiness of the network and the heterogeneousness of the hardware and software, developing context-aware applications on mobile and embedded devices is still complexand time-consuming. The ultimate reason is lacking a uniform middleware support. To address this problem, we proposed a lightweight middleware for pervasive computing, called FollowMeLite. FollowMeLite is part of FollowMe which is a perva sive infrastructure. Based on OSGi, it integrated Ontology based context model, workflow based programming model and network service for dynamic communication. By deploying different components, FollowMeLite can be applied to various application environments.
