CAREER: Etiquette for Collaborative Communications and NetworkingNSF 0643954, PI: Daniela TuninettiAbstractWireless networks have traditionally been deployed with interference avoidance as the primary objective to ensure high throughput. Recently, a new and exciting paradigm has emerged in which interfering communications from different users are viewed as a way to spread "common information" across the network, thereby allowing for cooperation among otherwise uncoordinated transmitters. Cooperative communications holds the potential to enhance the communication capabilities of all users in the network simultaneously if users share their resources with their neighbors. This research aims at establish a theoretical foundation for collaborative communications by identifying the optimal resource sharing conduct, here referred to as etiquette, among users in peer-to-peer wireless networks. It is centered on the interference channel with generalized feedback, a novel information-theoretic network model that incorporates the knowledge a communicating pair of users can infer about other concurrent communications from information overheard. This research has two main thrusts: (1) developing innovative coding and signaling techniques for resource sharing to improve capacity, and investigate the associated scaling laws, (2) designing efficient and distributed multi-access and routing protocols to realize the benefits of collaborative communications with minimal overhead. The goal is to shed light on a richer and more powerful class of cooperation modes than currently proposed multi-hop relaying, and to lay the foundations for a deeper understanding of the ultimate tradeoffs involved in peer-to-peer networking. The technical approach includes comprehensive theoretical analysis and extensive computer simulations on real network data. In addition, a new multidisciplinary course that bridges Information Theory and Networking Theory is developed to expose students to the benefits of cross-fertilizations of the two disciplines to the design of collaborative communication networks.

职业：协作通信和网络礼仪NSF 0643954，PI：Daniela TuninettiAbstract 传统上，无线网络的部署以避免干扰为主要目标，以确保高吞吐量。最近，出现了一种令人兴奋的新范例，其中来自不同用户的干扰通信被视为在网络上传播“公共信息”的一种方式，从而允许其他不协调的发射机之间进行合作。如果用户与邻居共享资源，协作通信就有可能同时增强网络中所有用户的通信能力。本研究旨在通过确定对等无线网络中用户之间的最佳资源共享行为（此处称为礼仪），为协作通信奠定理论基础。它以具有广义反馈的干扰信道为中心，这是一种新颖的信息论网络模型，其中包含一对通信用户可以从无意中听到的信息推断出其他并发通信的知识。这项研究有两个主旨：（1）开发用于资源共享的创新编码和信令技术以提高容量，并研究相关的扩展规律，（2）设计高效的分布式多路访问和路由协议以实现协作通信的好处以最小的开销。其目标是阐明比目前提出的多跳中继更丰富、更强大的合作模式，并为更深入地理解对等网络中涉及的最终权衡奠定基础。技术方法包括全面的理论分析和对真实网络数据的广泛计算机模拟。此外，还开发了一门连接信息论和网络理论的新多学科课程，让学生了解这两个学科交叉融合对协作通信网络设计的好处。
