随着普适计算技术的发展，世界将充满互连的上下文感知域（例如，家庭、办公室、医院等）。虽然之前的研究仅关注单个域中产生的上下文的管理，但在本文中，我们讨论了跨域上下文管理需要解决的挑战。通过分析几个场景的需求，我们确定了两个上下文生产者-消费者模式在多域环境中。此外，为了解决跨域上下文共享中出现的移动的实体问题，提出了一种透明的查询机制，使应用程序能够从远程域获取有关移动的实体的上下文信息。已经开发了两个原型应用程序-智能家居和社区服务在智能校园，以展示跨域上下文管理的关键功能和实用性。初步的实验也进行了评估我们的系统的性能。
With the development of pervasive computing techniques, the world will be filled with interconnected context-aware domains (e.g., homes, offices, hospitals, etc.). While the previous studies focused solely on the management of contexts produced in a single domain, in this paper we discuss the challenges to be addressed for cross-domain context management. By analyzing the requirements from several scenarios, we identify two context producer–consumer patterns in multi-domain environments. Furthermore, to deal with the mobile entity problem raised in cross-domain context sharing, a transparent query mechanism that enables applications to obtain context information about mobile entities from remote domains is proposed. Two prototype applications—smart home and community services in a smart campus—have been developed to demonstrate the key features and usefulness of cross-domain context management. Initial experiments have also been conducted to evaluate the performance of our system.
