Abstract

Context-awareness (CA) enables the development of personalized pervasive services. Current context-aware infrastructures focus on middleware solutions to support acquisition, usage and management of context. However, using context requires the CA application to create a binding between itself and one or more context producing entities. Creating this binding is the responsibility of the CA application developer, which is often an extensive manual task. The ad hoc availability of context-producing entities further complicates this responsibility. This paper proposes an application infrastructure, coined CACI, which offers a binding transparency to support rapid development of CA applications. CACI enables developers to specify context requirements at a high abstraction level using a declarative binding language. CACI also provides the creation and maintenance of bindings to context producing entities based on such specifications. This paper discusses the design and implementation of CACI. Additionally, it discusses the validation of CACI using a pervasive healthcare scenario

普及中间件中的动态上下文绑定

上下文感知(CA)支持开发个性化的普及服务。当前的上下文感知基础设施主要关注中间件解决方案，以支持上下文的获取、使用和管理。但是，使用上下文需要CA应用程序在自身和一个或多个生成上下文的实体之间创建绑定。创建此绑定是CA应用程序开发人员的责任，这通常是一项大量的手工任务。上下文生成实体的特别可用性使这一职责进一步复杂化。本文提出了一种应用程序基础结构，称为CACI，它提供了绑定透明性以支持CA应用程序的快速开发。CACI使开发人员能够使用声明性绑定语言在高抽象级别上指定上下文需求。CACI还提供了对基于此类规范的上下文生成实体的绑定的创建和维护。本文讨论了CACI的设计与实现。此外，本文还讨论了使用普遍医疗保健场景验证CACI的方法
