The world has witnessed an exponential growth in the number and demand of wireless devices, and an increase in the array of wireless broadband network applications that has permeated virtually all aspects of our daily lives. However, this progress cannot be sustained with the current wireless communication network technologies, and this fact has spurred research innovations towards the next generation of wireless systems, typically termed 5G technologies. Two key paradigm shifts that will help meet these demands in 5G networks are the deployment of heterogeneous small cell networks combined with device to device and multi-hop wireless communication, and the adoption of more innovative ways of sharing the spectrum through cognitive radio and dynamic spectrum access.This project provides tools for quantifying the design trade-offs in future spectrum-agile heterogeneous networks, as well as the theoretical performance limits. Several networks are expected to exist in the same geographical area, each with varying access rules and access protocols. The project studies co-existence and possible cooperation between such networks. Two modes of cooperation are considered: relay cooperation and content cooperation. Two approaches are considered for the analysis of each of these modes, which compose the two thrusts of the proposal: Thrust I: queuing network approaches, which characterize finite as well as asymptotic performance, and focus on random-access based schemes; and Thrust II: scheduling and optimization approaches, which characterize the theoretical best possible performance. The broader impacts of the work include the development of course projects and modules for two graduate level courses that integrate results from the two thrusts of this research, K-12 outreach, enhancement of student diversity and increase of number of women and under-represented groups in engineering, and international collaboration that offers international exposure for students.

世界已经见证了无线设备的数量和需求的指数增长，以及无线宽带网络应用阵列的增加，其几乎已经渗透到我们日常生活的各个方面。然而，这种进展无法用当前的无线通信网络技术来维持，并且这一事实已经刺激了对下一代无线系统（通常称为5G技术）的研究创新。有助于满足5G网络这些需求的两个关键范式转变是部署与设备到设备和多跳无线通信相结合的异构小型蜂窝网络，以及通过认知无线电和动态频谱接入采用更具创新性的频谱共享方式。该项目提供了量化未来频谱敏捷异构网络设计权衡的工具，以及理论性能极限。预期在同一地理区域中存在多个网络，每个网络具有不同的访问规则和访问协议。该项目研究这些网络之间的共存和可能的合作。考虑了两种合作模式：接力合作和内容合作。两种方法被认为是分析这些模式，这构成了两个推力的建议：推力一：排队网络的方法，其特点是有限的，以及渐近性能，并专注于随机接入为基础的计划;和推力二：调度和优化的方法，其特点是理论上最好的性能。这项工作的更广泛的影响包括为两门研究生课程开发课程项目和模块，这些课程整合了本研究的两个重点，K-12推广，学生多样性的增强以及工程领域妇女和代表性不足群体的数量增加，以及为学生提供国际曝光的国际合作。
