上下文感知所需的日益增加的复杂性使得这类应用程序难以编写和适应。在本文中，我们提出了一种架构，用于将上下文感知应用程序构建为对细粒度Web服务的动态组合调用序列，以解决普遍环境的反应性行为。这些序列的不同服务组合将由不同的上下文产生，例如：可用设备、带宽、时间限制、位置、用户需求和配置文件。我们使用SHOP2规划系统和BPEL4WS Web服务组合技术实现并讨论了一个特定的上下文感知动态服务组合问题。
The increasing complexity required for context awareness makes such applications difficult to write and adapt. In this paper, we present an architecture for building context aware applications as dynamically composed sequences of calls to fine granularity Web services, addressing the reactive behavior of pervasive environments. Different service compositions of such sequences will result from different contexts such as: devices available, bandwidth, time constraints, location, user requirements and profile. We implement and discuss a specific context aware dynamic service composition problem using the SHOP2 planning system and the BPEL4WS Web service composition technology.
