Cooperation under Competition: System implications for DSA and computing systems

许多基础设施行业已经完成了从私有制到公用事业的过渡，通常要经过中间阶段。人们相信，今天的计算正处于这种转变之中。pi相信基于无线的系统最终也会遵循同样的路线。这条路径有望缓解困扰新兴无线应用的频谱瓶颈。为了实现这一目标，技术进步必须引起相互竞争的公司的合作行为。这些进步必须利用无线电系统设计的进步，包括认知无线电。本研究在很大程度上依赖于系统设计方法和基于agent的仿真建模，探讨了合作、竞争和实现机制之间的关系，包括系统架构和协议设计，特别是agent局部优化。特别要注意的是不同方法对大量设备和异构使用的可伸缩性。在无线系统的应用中，研究特别关注可能产生传输机会（称为频谱洞）的方式。这些结果将使紧急应用程序更容易获得无线连接，从而使应用程序设计人员能够为用户构建具有明确质量期望的服务。建立了真实的模型，以便评估频谱空穴产生的机制及其通过协议的使用。研究结果将发表在主要的通讯会议和期刊上，并鼓励开发试点应用程序。

Many infrastructure industries have made the transition from private ownership to utility, often through intermediate stages. It is believed that computing is in the midst of this transition today. The PIs believe that wireless-based systems will follow the same route in time. This path promises to alleviate the spectrum bottlenecks that plague emergent wireless applications. For this to occur, technological advances must take place that elicit cooperative behavior from firms that also compete with each other. These advances must leverage advances in radio system design, including cognitive radios. Relying heavily on system design methodologies and agent-based simulation modeling, this research explores the relationships between cooperation, competition and the implementation mechanisms, including system architectures and protocol design, especially where agents optimize locally. Particular attention is paid to the scalability of different approaches to large numbers of devices and heterogeneous uses. In the application to wireless systems, the research pays particular attention to ways in which transmission opportunities (called spectrum holes) may be created. These outcomes will enable easier access to wireless connectivity to emergent applications, thus enabling application designers to build services with explicit quality expectations for their users. Realistic models are constructed so that the mechanisms for spectrum hole generation and their use through protocols can be evaluated. The results will be published in major communications conferences and journals, and the development of pilot applications will be encouraged.
