NeTS: Small: Collaborative Research: A Service Centric Architecture for Efficient Spectral Utilization in Wireless Networks

这个项目将开始质疑无线网络的基本设计范例，其中有有限的频谱资源，为大量的用户需要一套不同的服务。该项目的最终目标是将无线网络的应用基础从无线互联网扩展到可扩展的移动的医疗保健、急救人员、安全应用、运输、工厂自动化和机器人技术。该项目的主要优势将是带来理论基础，以及系统级设计和算法，以开发可实现的网络。PI计划与其行业合作伙伴密切合作，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解决频谱效率的新方法，反映了网络哲学的转变性质，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概念。未来服务中心网络的主要目标是分发内容和提供有关正在进行的过程的新信息。在过去的几年中，不同无线服务数量的增加给提供商的网络带来了前所未有的压力，以至于当前的架构无法扩展以满足用户需求的指数增长和服务的差异。为了应对危机，本研究满足了所需的范式转变，从静态的用户需求，并在雅阁与垂直集成的架构，利用功能的服务。该项目的驱动愿景是构建一个具有流行的以服务为中心的理念的无线网络。在这奋进，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，网络范围内的认知。在物理层练习“真正的认知”，网络中的节点将被假定为与灵活的无线电一起操作，并且网络对无线电接入技术是不可知的;然而，网络将被设计为利用这种灵活性。因此，网络范围认知的概念在无线网络设计的几个层上得到证实，并在两个耦合的推力中重新访问核心网络基础，一个是关于服务中心网络的调度，另一个是关于延迟敏感服务的网络供应。

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.
