本文提出了一种传感器网络中动态软件重构的方法。我们的方法利用嵌入式应用程序设计空间的显式模型。设计空间是通过对所有软件组件、它们的接口和它们的组合进行正式建模来获取的。系统需求表示为在运行时测量的QoS参数的正式约束。通过基于约束从操作空间的一个点转换到另一个点来执行重新配置。我们使用执行一维跟踪的简单传感器网络的仿真结果来演示我们的方法。
This work presents an approach for dynamic software reconfiguration in sensor networks. Our approach utilizes explicit models of the design space of the embedded application. The design space is captured by formally modeling all the software components, their interfaces, and their composition. System requirements are expressed as formal constraints on QoS parameters that are measured at runtime. Reconfiguration is performed by transitioning from one point of the operation space to another based on the constraints. We demonstrate our approach using simulation results for a simple sensor network that performs one-dimensional tracking.
