到岸价：中等：合作研究：跨层协作网络本研究超越了物理层，定义和分析无线网络的协作技术。通过结合更高层的属性，如交通动态和访问控制，研究人员开发了一种新的 分析和设计跨层协作组网算法的理论框架，其中包括现有的协作技术，如协作中继和网络编码。这项研究的基础在于两个主要点：第一，实现在物理层的合作通信不能孤立地看待，因为它在接入和网络层的影响，第二，认识。在更高层的合作本身可以显著地影响整体网络性能。这个项目有三个相互关联的推力：第一推力研究资源分配政策，稳定的队列内的各种合作网络，如果稳定性确实是可以实现的。第二推力确定了一个家庭的调度算法，最大限度地提高了交通量的合作网络在有限的地平线。最后，博弈论模型开发的合作网络中的节点被允许追求不同的目标，并达成分布式协议的（本地）最优的工作点为整个network.This研究还考虑了非平稳和非遍历的环境，更合适的无线信道在网络中的表示。

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.
