Modern wireless networks are complex dynamic systems that promise to provide the public with Internet access, new commercial and public safety services, and real-time information about the world at any location and any time. Without a unifying analytical framework, though, the promises of wireless technology will not be fully realized. This project is exploring the application of game theory, an analysis tool that has been successful in explaining complex economic systems, to create an analytical framework for wireless networks.Specifically, the project is developing a theory of cooperation to explain how network nodes with disparate and limited information can cooperate to achieve network-wide goals. This theory is based on the game-theoretic notion of a potential game, and makes game theory more useful for engineering applications. The nascent theory is being applied to produce optimal algorithms for controlling transmission power and selecting code sequences in a wireless network. This work is expected to lead to more efficient power control and interference avoidance algorithms, thus improving the performance of wireless networks and using radio spectrum (an important public resource) more efficiently. More importantly, though, this research is developing fundamental analytical tools that will enable other researchers to create more efficient and more powerful wireless networks for a wide variety of applications.While pursuing these important research aims, the project also includes strong education components which introduce K-12 students to wireless technology with hands-on activities designed to stimulate interest in electrical and computer engineering and wireless communications.

现代无线网络是复杂的动态系统，有望为公众提供互联网接入、新的商业和公共安全服务以及随时随地的世界实时信息。然而，如果没有统一的分析框架，无线技术的前景将无法完全实现。该项目正在探索应用博弈论（一种成功解释复杂经济系统的分析工具）来创建无线网络的分析框架。具体来说，该项目正在开发一种合作理论，以解释不同和不同网络节点之间的关系。有限的信息可以合作实现全网络的目标。该理论基于潜在博弈的博弈论概念，使博弈论在工程应用中更加有用。 这一新兴理论正被应用于产生用于控制无线网络中的传输功率和选择代码序列的最佳算法。 这项工作预计将带来更有效的功率控制和干扰避免算法，从而提高无线网络的性能并更有效地使用无线电频谱（重要的公共资源）。但更重要的是，这项研究正在开发基础分析工具，使其他研究人员能够为各种应用创建更高效​​、更强大的无线网络。在追求这些重要研究目标的同时，该项目还包括强大的教育部分，其中介绍了 K -12 名学生通过旨在激发电气和计算机工程以及无线通信兴趣的实践活动来接触无线技术。
