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.

媒介：协作研究：跨层协作网络本研究在定义和分析无线网络的协作技术方面超越了物理层。通过结合更高的层属性，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，用于分析和设计跨层的合作网络算法，其中包括现有的合作技术，如合作中继和网络编码。本研究的基础在于两点：第一，认识到物理层的协作通信不能孤立地看待，因为它对接入层和网络层都有影响；第二，识别。高层的合作，就其本身而言，可以显著影响整体网络性能。该项目有三个相互关联的重点：第一个重点研究资源分配策略，该策略可以稳定各类合作网络中的队列，如果稳定性确实可以实现的话。第二个推力决定了一系列调度算法，这些算法可以在有限视界内最大化合作网络的交通量。最后，建立了协作网络的博弈论模型，其中网络中的节点被允许追求不同的目标，并就整个网络的（局部）最佳工作点达成分布式协议。本研究还考虑了非平稳和非遍历环境，这些环境更适合表示网络中的无线信道。
