This project develops a new vision for wireless networks, predicated on the creation of service-driven virtual networks constructed from a pool for resources that belong to a variety of stakeholders. The resources include spectrum, physical infrastructure, and control and management support, and the stakeholders include traditional mobile operators, operators of WiFi access networks, businesses and households that support wireless connectivity through small cell deployment, traffic aggregators (such as Mobile Virtual Network Operators [MVNOs]), and regulators. The resulting architecture separates the consumer-facing service provision from the technologies used to construct the network, enabling the disintermediation of current wireless service provision systems. Moving the point at which network access transactions take place up the value chain (or the protocol stack) means that a greater range of service types can be provided to consumers without requiring large up-front capital investments on the part of the (consumer-facing) service providers. This will have profound impact on both industry and society, affecting the way that these networks are designed and built, spectrum and infrastructure resources are managed, and pricing structures for services provided over the network.This project first defines a new architecture that enables the virtualization of a wireless network over a combination of spectrum licensed under different regimes and infrastructure with different ownership. Relying on game theoretic and market models of virtual network construction, new resource management mechanisms are designed to select the appropriate set of resources to build a virtual wireless network with given coverage and capacity requirements. Combinatorial auctions for multiple objects are practical mechanisms for the dynamic allocation and aggregation of resources for such a virtualized wireless network. In analyzing the impact of the proposed architecture on spectrum markets, a key question is whether the incorporation of a virtualized spectrum commodity influences the viability of these markets (as measured by the liquidity outcome), and how this compares to previous scenarios in which the traded commodity was the physical spectrum resource or 'naked spectrum;. Finally, this project explores how markets in virtual wireless capacity would work when implemented in current wireless networks, in the context of LTE-Advanced and expected 5G developments.

该项目为无线网络开发了新的愿景，这是基于由服务驱动的虚拟网络创建的，该虚拟网络是为属于各种利益相关者的资源而建立的。资源包括频谱，物理基础架构以及控制和管理支持，利益相关者包括传统的移动运营商，WiFi访问网络的运营商，企业和家庭的运营商，通过小组部署，交通聚合器（例如移动虚拟网络运营商[MVNOS]）以及监管机构以及监管机构以及监管机构。最终的体系结构将面向消费者的服务提供与用于构建网络的技术分开，从而使当前的无线服务提供系统的解关性分开。移动网络访问交易进行的点（或协议堆栈）意味着可以向消费者提供更大的服务类型，而无需（面向消费者）服务提供商需要大量前前的资本投资。这将对工业和社会产生深远的影响，影响这些网络的设计和构建方式，频谱和基础架构资源的管理，以及在网络上提供的服务的定价结构。该项目首先定义了一种新的体系结构，该项目可以在不同的制度和基础构造与不同的机构授权下实现无线网络的虚拟化。依靠虚拟网络构建的游戏理论和市场模型，新的资源管理机制旨在选择适当的资源集，以构建具有给定覆盖范围和容量要求的虚拟无线网络。多个对象的组合拍卖是用于这种虚拟化无线网络的动态分配和资源汇总的实用机制。在分析拟议的建筑对频谱市场的影响时，一个关键问题是，合并虚拟谱商商品是否会影响这些市场的生存能力（按流动性结果衡量），以及与以前的场景相比，该市场如何进行交易的商品是物理资源或'naked spectrum; naked spectrum;最后，该项目探讨了在当前无线网络中实施的虚拟无线容量市场如何在LTE高级和预期的5G开发中实施。
