NeTS: Medium: Collaborative Research: Enabling Cellular Services over Unplanned Femto-Cell Deployments: From Theory to Implementation

建议的研究的目的是开发的基础上，在毫微微蜂窝网络的资源分配，并使用真实的测试床的解决方案的性能进行评估。 由于四个主要原因，基于毫微微小区的网络中的无线资源分配尤其具有挑战性：（1）毫微微小区之间以及毫微微小区与宏小区之间的干扰;（2）每个毫微微小区与运营商的网络之间的信令和数据通信中的可变且不可预测的延迟;（3）用于通过无线信道向大量毫微微小区发送信令的有限带宽;（4）用于通过无线信道向多个毫微微小区发送信令的有限带宽。以及（4）涉及具有不同优先级的三方：运营商、用户和毫微微小区所有者。 本项目的具体研究任务是：（1）针对传统系统，在不改变现有硬件和标准的前提下，开发宏小区和毫微微小区协同部署下的下行链路和上行链路调度和切换的分布式解决方案;（2）发展分布式，自适应和自组织解决方案（不受传统要求的限制），通过使用统计物理学中称为Glauber动力学的强大工具进行资源分配;以及（3）设计机制以在涉及最终用户、毫微微小区所有者和运营商的实际设置中促进离线真实拍卖。 这些解决方案将在密歇根大学和俄亥俄州州立大学正在开发的两个测试平台上实施和评估。 拟议的研究有可能对手机行业和最终用户产生重大影响。鉴于全球手机的高渗透率，这项研究具有直接和广泛的影响。

The objective of the proposed research is to develop the foundations for resource allocation in femtocell networks, and evaluate the performance of the solutions using real testbeds. Wireless resource allocation in femtocell-based networks is particularly challenging due to four main reasons: (1) interference between femtocells and between femto- and macro-cells; (2) variable and unpredictable delays in signaling and data communication between each femtocell and the operator's network; (3) limited bandwidth for signaling over a wireless channel to a large number of femtocells; and, (4) involvement of three parties with differing priorities: the operator, the users, and the femtocell owners. The specific research tasks in this project are: (1) For legacy systems, develop distributed solutions for both downlink and uplink scheduling and handover under co-deployment of macro- and femto-cells that do not require any changes to existing hardware and standards; (2) Develop distributed, adaptive and self-organizing solutions (unconstrained by legacy requirements) for resource allocation by using a powerful tool from statistical physics, called Glauber dynamics; and (3) Design mechanisms to facilitate offline truthful auctions in practical settings involving the end-users, the femtocell owners, and the operator. The solutions will be implemented and evaluated on two testbeds under development at University of Michigan and at Ohio State University. The proposed research has the potential to significantly impact the cellular industry and end-users. Given the high penetration rates of cell-phones worldwide, this research has an immediate and widespread impact.
