NeTS-NOSS: Unified and Configurable Power Management for Wireless Sensor Networks

电源管理对无线传感器网络至关重要，因为许多应用都有两个共同的特点：无线传感器网络必须在电池上运行，因为在部署环境中无法获得有线电源；同时，它们必须达到极长的使用寿命。尽管早期对各种电源管理策略进行了研究，但应用程序开发人员仍然面临着将多种电源管理策略集成到整个传感器网络的一致解决方案中的重要挑战。此外，随着传感器网络应用和平台的不断发展，为各种应用和网络平台提供灵活的电源管理非常重要。为了应对上述挑战，该项目开发了统一可配置电源管理（UCPM），这是无线传感器网络中可配置和可组合电源管理的统一框架。UCPM框架包括三个创新组件：(1)促进不同电源管理策略集成的统一架构抽象，(2)描述应用程序、网络平台和电源管理策略关键属性的高级建模抽象，以及(3)为给定应用程序和网络生成定制的集成电源管理策略的配置和分析工具。UCPM体系结构和工具使应用程序开发人员能够提高网络的使用寿命，同时降低开发成本，并降低诸如结构健康监测和野火监测等电力关键应用程序的延迟。UCPM框架将通过集成整个传感器网络架构和广泛使用的传感器网络操作系统，传播到广泛的开发人员社区。

Power management is critical to wireless sensor networks because of two characteristics shared by many applications: wireless sensor networks must operate on batteries as wired power supplies are inaccessible in deployment environments; and at the same time they must achieve extremely long operational lifetimes. Despite earlier research on various power management strategies, application developers still face the important challenge of integrating multiple power management strategies into a coherent solution for an entire sensor network. Furthermore, as sensor network applications and platforms continue to evolve, it is important to support flexible power management for diverse applications and network platforms. To address the challenges above, this project develops a Unified and Configurable Power Management (UCPM), a unified framework for configurable and composible power management in wireless sensor networks. The UCPM framework comprises three innovative components: (1) unified architectural abstractions that facilitate the integration of different power management strategies, (2) high-level modeling abstractions that characterize the key properties of applications, network platforms, and power management strategies, and (3) configuration and analysis tools that generate integrated power management strategies customized for given applications and networks. The UCPM architecture and tools enable application developers to improve network lifetime while reducing development cost and delay for power-critical applications such as structural health monitoring and wild fire monitoring. The UCPM framework will be disseminated to the broad developer community through its integration with overall sensor network architecture and a widely used operating system for sensor networks.
