This project will begin by questioning the basic design paradigms of wireless networks, where there are limited spectral resources for a large population of users needing a diverse set of services. The ultimate goal of the project is to expand the application base of wireless networks from wireless Internet, to include scalable mobile healthcare, first-responders, security applications, transportation, factory automation and robotics. The main strength of the project will be to bring theoretical foundations, as well as system level designs and algorithms to develop a realizable network. The PIs plan to work closely with their industrial partners to ensure that project outcomes impact next-generation wireless networks. This research presents a fundamentally novel approach to address spectrum efficiency that reflects the shifting nature of networking philosophy as networks migrate from the classical paradigm of well-defined users and operators to the notion that networking is a tool for the provision of services. Then the primary objective of future service centric networks is to distribute content and to provide fresh information about on-going processes. Over the last few years, the rise in the number of different wireless services has put unprecedented pressure on providers' networks, to the point that current architectures cannot scale to meet the exponential growth of users' demands and the dissimilarities in the services. To confront the crisis, this research meets the required paradigm shift away from a static view of users' needs and in accord with a vertically integrated architecture to harness features of the services. The driving vision in this project is to architect a wireless network with a prevailing service centric philosophy. The concept of network-wide cognition is introduced in this endeavor to explore attributes and disparities of these services as well as heterogeneity of network nodes. Exercising 'true cognition' at the physical layer, nodes in the network will be assumed to operate with flexible radios and that the network is agnostic to the radio access technology; however, the network will be designed to exploit this flexibility. Therefore, the concept of network- wide cognition substantiates across several layers of wireless network design and revisits core network foundations in two coupled thrusts one on scheduling for service centric networking and the other on network provision for delay sensitive services.

该项目将首先质疑无线网络的基本设计范例，在那里，对于需要多种服务的大量用户来说，光谱资源有限。该项目的最终目标是将无线网络的应用程序库从无线互联网扩展，包括可扩展的移动医疗保健，第一响应者，安全应用程序，运输，工厂自动化和机器人技术。该项目的主要优势是带来理论基础，以及系统级别的设计和算法以开发可实现的网络。 PIS计划与其工业合作伙伴紧密合作，以确保项目成果影响下一代无线网络。这项研究提出了一种从根本上进行新颖的方法来解决光谱效率，这反映了网络理念的转移性质，因为网络从定义明确的用户和运营商的经典范式迁移到网络是提供服务的工具的观点。那么，以未来服务的网络的主要目标是分发内容并提供有关正在进行过程的新信息。在过去的几年中，不同无线服务的数量增加给提供商的网络带来了前所未有的压力，以至于当前的体系结构无法扩展以满足用户需求的指数增长和服务的差异。为了面对这场危机，这项研究符合所需的范式从对用户需求的静态视图和垂直集成的体系结构转变为服务的功能。该项目的驾驶视野是构建具有以服务为中心的哲学的无线网络。在这项努力中介绍了探索这些服务的属性和差异以及网络节点的异质性的概念。在物理层上行使“真实认知”，将假定网络中的节点具有灵活的收音机，并且网络对无线电访问技术不可知。但是，该网络将旨在利用这种灵活性。因此，网络认知的概念证实了几层无线网络设计的概念，并重新审视了两个耦合的核心网络基础，一个在安排以服务为中心的网络的安排时，另一个是在网络提供延迟敏感服务上。
