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.

本研究的目的是为移动蜂窝网络中的资源分配奠定基础，并利用真实的测试平台评估解决方案的性能。由于以下四个主要原因，基于飞蜂窝网络的无线资源分配尤其具有挑战性：(1)飞蜂窝之间以及飞蜂窝与大蜂窝之间的干扰；(2)每个移动基站与运营商网络之间的信号和数据通信存在可变和不可预测的延迟；(3)用于通过无线信道向大量飞基站发送信号的有限带宽；(4)具有不同优先级的三方参与：运营商、用户和移动基站所有者。本项目的具体研究任务是：(1)对于遗留系统，在宏蜂窝和飞蜂窝的共同部署下，开发下行和上行调度和切换的分布式解决方案，不需要对现有硬件和标准进行任何更改；(2)利用统计物理学中的一种强大工具，即Glauber动力学，为资源分配开发分布式、自适应和自组织的解决方案（不受遗留需求的约束）；(3)设计机制，在涉及终端用户、移动基站所有者和运营商的实际环境中促进线下真实拍卖。这些解决方案将在密歇根大学和俄亥俄州立大学正在开发的两个试验台上实施和评估。拟议的研究有可能对蜂窝产业和最终用户产生重大影响。鉴于手机在世界范围内的高普及率，这项研究具有直接和广泛的影响。
