上下文感知计算近年来得到了广泛的研究，但缺乏一个强大的上下文感知中间件，支持一个统一的编程模型。因此，开发上下文感知的应用程序仍然是复杂和耗时的。我们介绍了一个名为FollowMe的工作流嵌入式中间件。它支持可插拔的上下文感知应用程序。FollowMe包括一个工作流引擎，并支持使用pvPDL描述的应用程序，pvPDL是一种专门为上下文感知而提出的工作流定义语言。工作流技术的应用简化了应用程序的开发，使应用程序的维护更加容易.最后通过一个实例的实现和相关的评价来验证这种改进。
Context-aware computing is widely researched in recent years, but we lack for a powerful context-aware middleware which supports a uniform programming model. So developing context-aware applications is still complex and time-consuming. We introduce a workflow embedded middleware called FollowMe. It supports pluggable context-aware applications. FollowMe includes a workflow engine and sustains applications described with pvPDL, which is a workflow definition language proposed specially for context-awareness. The employment of workflow makes the development of applications simplified and the maintenance much easier. We testify the improvement by realizing an example and the related evaluation.
