CAREER: Etiquette for Collaborative Communication and Networking

职业：协作通信和网络的礼仪NSF 0643954，PI：Daniela Tuninetti摘要传统上，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，出现了一种新的和令人兴奋的范例，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，从而允许在其他不协调的发射机之间进行合作。协作通信是指网络中的用户通过与邻居共享资源来提高网络中所有用户的通信能力。本研究的目的是建立一个理论基础，通过确定最佳的资源共享行为，这里被称为礼仪，在对等无线网络中的用户之间的协作通信。它是集中在干扰信道与广义反馈，一种新的信息理论的网络模型，结合了知识的通信对用户可以推断其他并发通信从信息偷听。本研究有两个主要的目标：（1）开发创新的编码和信令技术，资源共享，以提高容量，并研究相关的缩放律，（2）设计高效的和分布式的多址接入和路由协议，以实现协同通信的好处，以最小的开销。我们的目标是阐明一个更丰富，更强大的一类合作模式比目前提出的多跳中继，并奠定基础，更深入地了解最终的权衡参与对等网络。技术方法包括对真实的网络数据进行全面的理论分析和广泛的计算机模拟。此外，一个新的多学科课程，桥梁信息理论和网络理论的开发，让学生接触到这两个学科的交叉施肥协作通信网络的设计的好处。

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.
