CIF: Medium: Collaborative Research: Cooperative Networking Across the LayersThis research goes beyond the physical layer in defining and analyzing cooperative techniques for wireless networks. By incorporating higher layer properties such as traffic dynamics and access control, the investigators develop a new theoretical framework for analyzing and designing cooperative networking algorithms across the layers, which includes existing cooperative techniques such as cooperative relaying and network coding. The basis of this research rests on two major points:: first, the realization that cooperative communication at the physical layer cannot be viewed in isolation, since it has implications at the access and network layers, and second, the recognition . that cooperation at the higher layers, in its own right, can significantly impact overall network performance. This project has three inter-related thrusts: The first thrust studies resource allocation policies which stabilize the queues within various classes of cooperative networks, if stability is indeed attainable. The second thrust determines a family of scheduling algorithms which maximize the volume of traffic served by a cooperative network within a finite horizon. Finally, game theoretic models are developed for cooperative networks where nodes in the network are allowed to pursue differing objectives, and come to a distributed agreement on the (locally) optimal operating point for the overall network.This research also considers non-stationary and non-ergodic environments that are more appropriate representations of the wireless channel in a network.

CIF：媒介：协作研究：整个层次的合作网络这一研究在定义和分析无线网络的合作技术方面超越了物理层。通过纳入较高的层属性，例如流量动态和访问控制，研究人员开发了一个新的理论框架，用于分析和设计整个层的合作网络算法，其中包括现有的合作技术，例如合作中继和网络编码和网络编码。这项研究的基础取决于两个主要要点::首先，意识到在物理层的合作通信不能孤立地观看，因为它在访问和网络层上具有影响，其次是识别。在较高层的合作本身可以显着影响整体网络性能。该项目具有三个相互关联的推力：第一个推力研究资源分配政策，如果确实可以实现稳定，则可以稳定各类合作网络中的队列。第二个推力决定了调度算法的家族，该算法最大程度地提高了有限地平线内合作网络服务的流量量。最后，为合作网络开发了游戏理论模型，在该网络中，网络中的节点被允许追求不同的目标，并就整个网络的（本地）最佳操作点达成了分布式协议。这项研究还考虑了非固定和非迫切环境，这些环境是网络中无线渠道更合适的代表。
