CAREER: Judicious Resource Management in Wireless Systems

移动设备的资源限制严格限制了无线应用程序在日益分散的世界中的效用和质量。虽然以前在资源管理方面有大量的工作，但解决移动系统资源相互依赖的复杂问题的研究却很缺乏。例如，大多数现代移动设备采用多种技术来减少它们的能源需求，然而，这些技术只关注单个资源，而没有意识到它们的部署可能对其他资源和应用程序性能产生的影响。此外，在分布式系统中，设备通常是自私的，因为它们管理自己的资源，而不考虑远程设备上的资源和应用程序的后果。NSF CAREER研究项目正在开发两个方面，一个是研究这些相互依赖关系和设计问题的实验框架，另一个是提供资源管理解决方案的新服务概念，使多种约束、资源和设备能够有效集成。这种新方法被称为明智的资源管理，它摆脱了传统的、孤立的资源管理解决方案，专注于预防相互依赖的资源适应带来的意想不到的副作用。这个项目更广泛的影响包括一个实验环境，它应该作为未来分布式资源管理研究的催化剂，为新类型的协议、管理技术和集成它们的方法铺平道路。这项工作将研究和教育活动紧密结合起来，使用单一的实验测试平台进行研究、教育和推广工作。

The resource constraints of mobile devices put strict limits on the utility and quality of wireless applications in an increasingly nomadic world. While there has been an abundance of previous work on resource management, there has been a dearth of research to address the complex problem of resource interdependencies for mobile systems. For example, most modern mobile devices employ multiple techniques to reduce their energy requirements, however, these techniques focus on individual resources and are unaware of the effects their deployment may have on other resources and application performance. Further, in distributed systems, devices typically are selfish in the sense that they manage their own resources without considering the consequences for resources and applications on remote devices. This NSF CAREER research project is developing both, an experimental framework for investigating these interdependencies and design issues, and new service concepts to provide resource management solutions that enable the efficient integration of multiple constraints, resources, and devices. The new approach, dubbed judicious resource management, moves away from traditional, isolated resource management solutions and focuses on the prevention of unanticipated side effects of interdependent resource adaptations. The broader impacts of this project include an experimental setting that should serve as catalyst for future research on distributed resource management, paving the way for new classes of protocols, management techniques, and approaches to integrate them. This work closely integrates research and education activities, using a single experimental test bed for research, education, and outreach efforts.
