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.

许多基础设施行业已从私人所有制过渡到公用事业，通常是经过中间阶段。据信，计算今天正处于这一转变之中。 PI认为，基于无线的系统将及时遵循相同的路线。这条道路有望缓解困扰新兴无线应用的频谱瓶颈。要做到这一点，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。在很大程度上依赖于系统设计方法和基于代理的仿真建模，本研究探讨了合作，竞争和实现机制，包括系统架构和协议设计，特别是在代理优化本地之间的关系。特别注意的是不同的方法，大量的设备和异构用途的可扩展性。在无线系统的应用中，研究特别关注可能产生传输机会（称为频谱空洞）的方式。这些成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其用户构建具有明确质量期望的服务。现实的模型构建，使频谱空洞产生的机制和它们的使用，通过协议可以进行评估。研究结果将在主要的通信会议和期刊上发表，并将鼓励开发试点应用程序。
