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：合作通信和网络网络0643954，PI：Daniela Tuninetiabstractwireless网络的礼节传统上是在干预避免的情况下被部署的，是确保高吞吐量的主要目标。最近，出现了一种新的令人兴奋的范式，其中干涉来自不同用户的通信被视为在整个网络中传播“常见信息”的一种方式，从而允许在其他不协调的发射器之间进行合作。如果用户与邻居共享资源，合作通信具有同时增强网络中所有用户的通信能力的潜力。这项研究旨在通过在点对点无线网络中的用户中确定最佳资源共享行为（称为礼节）来建立协作通信的理论基础。它以广义反馈为中心，这是一种新型的信息理论网络模型，结合了知识，通信对用户可以从信息听到的信息中推断出其他并发通信。这项研究有两个主要的推力：（1）开发创新的编码和信号传导技术，以提高容量，并研究相关的缩放定律，（2）设计有效的和分布式的多访问和路由协议，以实现与最小开销的协作通信的好处。目的是阐明比目前提出的多跳继电器更丰富，更强大的合作模式，并为对点对点网络所涉及的最终权衡做出更深入的了解。技术方法包括对实际网络数据的全面理论分析和广泛的计算机模拟。此外，开发了一个新的跨学科课程，该课程桥接信息理论和网络理论是为了使学生揭露这两个学科的交叉施用的好处，以实现协作通信网络的设计。
