Wireless networks have grown rapidly, resulting in increased productivity afforded by untethered mobile communications. The end-to-end communication problem for wireless networks includes physical layer (PHY), Medium Access Control (MAC), and routing issues. This effort aims to provide a joint solution to the end-to-end problem, encompassing all three areas, to maximize efficiency by attempting to unify the theories that support them, namely information theory, queuing and graph theory.Specifically, the MAC problem is being investigated for a variety of situations, incorporating diverse traffic characteristics, advanced physical layer technologies, and potential denial of service, and efficient protocols are being designed. The effect on routing of channel fading is being investigated. The novelty of the project is in the use of information theoretic techniques, such as entropy bounds and error exponents, to analyze MAC and routing, thus complementing queuing and graph theoretic analysis.This project aims to increase the efficiency of wireless networks, whose development is important for the continued growth of global productivity. The project will result in the understanding and design of efficient MAC and routing protocols, which explicitly incorporate PHY characteristics, and are capable of handling practical wireless channel impairments, arising in diverse wireless networks. The results will be of importance to the communications industry in designing high-end competitive products. Further, the project will develop graduate student expertise in information theoretical techniques for wireless networking, and will allow several more undergraduates and graduates to participate through instructional experiments.

无线网络已经迅速发展，导致由无限制的移动的通信提供的生产率增加。无线网络的端到端通信问题包括物理层（PHY）、介质访问控制（MAC）和路由问题。这项工作的目的是提供一个联合解决方案的端到端的问题，包括所有三个领域，以最大限度地提高效率，试图统一的理论，支持他们，即信息论，排队和图论。具体来说，MAC问题正在研究的各种情况下，结合不同的流量特性，先进的物理层技术，和潜在的拒绝服务，并且正在设计有效的协议。信道衰落对路由选择的影响正在研究中。该项目的新奇在于使用信息理论技术，如熵界和错误指数，分析MAC和路由，从而补充排队和图论分析。该项目旨在提高无线网络的效率，其发展对全球生产力的持续增长至关重要。该项目将导致有效的MAC和路由协议的理解和设计，明确纳入物理层特性，并能够处理实际的无线信道损伤，在不同的无线网络中出现。研究结果对通信行业设计具有竞争力的高端产品具有重要意义。此外，该项目将发展研究生在无线网络信息理论技术方面的专业知识，并将允许更多的本科生和研究生通过教学实验参与。
