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.**

尽管不断进行研究以开发高效的无线技术，但无线网络最终总是面临超出其能力的容量需求。这一趋势将继续下去，预计容量需求将增长数量级，机器对机器(M2M)通信的增加也将是一个重要转变。为了更好地满足持续不断的无线接入需求，研究界考虑了几项关键技术。在此背景下，本研究计划特别考虑通过开发和分析用于未来毫米波无线网络的媒体访问控制(MAC)技术来优化整体网络效率，其中使用定向天线来降低传播损耗。巨大的毫米波频谱使数据速率提高了数倍，并有效地部署了连续的无线网络。此外，毫米波网络具有许多特性，使得使用具有认知无线电的动态频谱接入(DSA)的操作成为一种有前景的方法，以根据需要有效地部署不同的网络来共享这一巨大的频谱。*因此，该研究计划的总体目标是提供和分析MAC技术，以使集群在不同无线通信网络中的多个设备能够有效地共享广泛的毫米波频谱，每个设备具有不同的服务质量要求和能力。更具体地说，将开发考虑使用定向天线的感知技术，设计适合于毫米波通信实际的异质网络的动态频谱分配算法，并提出和分析适用于具有定向天线设备的异类多频段毫米波认知无线电网络的MAC协议，该协议与业界采用的网络结构更好地兼容。在这项工作中将使用优化工具、启发式算法和模拟工具来实现这些目标。*当前用于毫米波无线网络的MAC协议通常是针对微波频率开发的协议的直接改编，并且没有考虑到巨大的毫米波频谱的特殊性而设计。因此，预计拟议的研究项目将对不断增长的毫米无线网络领域做出重大研究贡献，该领域被预见为未来提供更多无线容量的主要途径。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，它应该有助于认知毫米波无线电和定向天线技术在未来的高速无线网络中的成功整合。
