Despite ongoing research efforts to develop efficient wireless techniques, wireless networks always eventually face capacity demands exceeding their capabilities. This trend will continue with orders of magnitude expected growth in capacity demands and also an important shift with increasing machine-to-machine (M2M) communications. To properly serve the continuing demands for wireless access, several key technologies are considered by the research community. In this context, this research program specifically contemplates optimizing overall network efficiency with the development and analysis of medium access control (MAC) techniques for future millimeter wave wireless networks where directional antennas are used to mitigate the propagation loss. The vast millimeter wave spectrum then enables multi-fold data rate increase and the efficient deployment of contiguous wireless networks. Furthermore, millimeter wave networks have a number of properties that make operations using dynamic spectrum access (DSA) with cognitive radios a promising approach to efficiently deploy on a per need basis heterogeneous networks to share this vast spectrum. The general objective of this research program is thus to provide and analyze MAC techniques to enable multiple devices clustered in different wireless communication networks, each with various quality of service requirements and capabilities, to efficiently share the broad millimeter wave spectrum. More specifically, sensing techniques considering the use of directional antennas will be developed, dynamic spectrum allocation algorithms for heterogeneous networks and adapted to the reality of millimeter wave communications will be devised, and MAC protocols for heterogeneous multi-band millimeter wave cognitive radios networks with devices equipped with directional antennas, and preferably compatible with network architectures adopted by the industry, will be proposed and analyzed. Optimization tools, heuristics algorithms, and simulation tools will be used in this work to achieve those objectives. Current MAC protocols for millimeter wave wireless networks are generally straightforward adaptations of protocols developed for microwave frequencies and have not been designed taking into account the particularities of the vast millimeter wave spectrum. It is therefore expected that the proposed research project will yield significant research contributions to the growing field of millimeter wireless networks, foreseen as the main approach to provide additional wireless capacity in the future. Those results will be of interest to wireless service providers, equipment manufacturers, standardization organizations and the research community. As such, it should contribute to the successful integration of cognitive millimeter wave radios and directional antenna techniques in future high-speed wireless networks.

尽管正在进行的研究努力，以开发有效的无线技术，无线网络总是最终面临的容量需求超过他们的能力。这一趋势将随着容量需求的数量级增长以及随着机器对机器（M2M）通信的增加而发生的重要转变而继续下去。为了适当地服务于对无线接入的持续需求，研究界考虑了几种关键技术。在这种情况下，本研究计划专门考虑优化整体网络效率与媒体访问控制（MAC）技术的发展和分析未来的毫米波无线网络，定向天线用于减轻传播损耗。广阔的毫米波频谱使数据速率成倍增加，并有效部署连续无线网络。此外，毫米波网络具有许多属性，这些属性使得使用动态频谱接入（DSA）与认知无线电的操作成为一种有前途的方法，以在每个需要的基础上有效地部署异构网络来共享这个巨大的频谱。 因此，本研究计划的总体目标是提供和分析MAC技术，使多个设备集群在不同的无线通信网络中，每个具有不同的服务质量要求和能力，有效地共享广泛的毫米波频谱。更具体地说，将开发考虑使用定向天线的感测技术，将设计用于异构网络并适应于毫米波通信现实的动态频谱分配算法，以及用于异构多频带毫米波认知无线电网络的MAC协议，该网络具有配备有定向天线的设备，并且优选地与业界采用的网络架构兼容，将提出并分析。在这项工作中，将使用优化工具，算法和仿真工具来实现这些目标。 用于毫米波无线网络的当前MAC协议通常是针对微波频率开发的协议的直接适配，并且没有考虑到广阔的毫米波频谱的特殊性来设计。因此，预计拟议的研究项目将产生重大的研究贡献毫米无线网络的不断增长的领域，预计作为主要方法，以提供额外的无线容量在未来。这些结果将引起无线服务提供商、设备制造商、标准化组织和研究界的兴趣。因此，它应该有助于在未来的高速无线网络的认知毫米波无线电和定向天线技术的成功集成。
