Economic Models for Collaborative Access Network Provisioning: US-Finland Collaboration

无线网络容量的增加主要来自于小区尺寸的缩小，但是对于大型运营商来说，继续这种趋势已经变得不切实际。小型无线网络也在过度拥挤的频段中捉襟见肘。这些问题在高密度802.11部署中尤为严重。很明显，利用运营商的大型基础设施部署和802.11和毫微微蜂窝网络的分布式部署的协作方法可能是非常有益的。本项目主要研究与异构无线网络相关的三个主要问题。首先，模型的开发，量化的收益之间的合作，大型运营商和小型运营商和最终用户部署自己的无线接入网络。其次，博弈论和定价模型的开发，研究激励结构，以支持异构无线网络中的协作。第三，开发了一个威胁模型，通过全面的脆弱性评估，专门建模的安全威胁，会影响一个异构的无线网络。这三项任务都通过频繁的原型设计和实验来补充。这项工作将立即适用于真实的网络，并将量化网络运营商合作的好处。此外，该合作项目将深化美国和芬兰之间的技术合作。在这个项目中开发的模型将在科学文献中提供并发表，提供对异构无线网络的全面理解。这些模型将促进协议和标准的进一步技术发展，以支持开放的异构无线网络。

Increased capacity in wireless networks has largely come from shrinking cell sizes, but continuing this trend has become impractical for large operators. Small wireless networks are also straining in overcrowded spectrum bands. The problems are particularly acute in high-density 802.11 deployments. It is clear that a collaborative approach, taking advantage of both large infrastructure deployment by operators and distributed deployments of 802.11 and femtocell networks could be extremely beneficial. This project focuses on three major problems related to heterogeneous wireless networks. First, models are developed that quantify the gains from cooperation between large operators and small-scale operators and end users deploying their own wireless access networks. Second, game theoretic and pricing models are developed to study incentive structures to support collaboration in heterogeneous wireless networks. Third, a threat model is developed to specifically model security threats that would impact a heterogeneous wireless network through a holistic vulnerability assessment. These three tasks are all complemented by frequent prototyping and experimentation.This work will be immediately applicable to real networks and will quantify the benefits of collaboration for network operators. In addition, the collaborative project will deepen technological collaboration between the United States and Finland. The models developed in this project will all be available and published in the scientific literature, providing a holistic understanding of heterogeneous wireless networks. These models will catalyze the further technical development of protocols and standards to support open, heterogeneous wireless networks.
