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开发有效的无线技术，但无线网络最终总是面临超出其能力的能力需求。这种趋势将继续随着产能需求的预期增长的预期增长而继续，并且随着机器对机器（M2M）通信的增加，这一趋势也将继续存在。为了适当满足对无线访问的持续要求，研究界考虑了几种关键技术。在这种情况下，该研究计划专门考虑优化整体网络效率，并通过对未来毫米波无线网络的中等访问控制（MAC）技术进行开发和分析，其中使用方向天线来减轻传播损失。然后，巨大的毫米波频谱实现了多倍数据速率的增加以及连续无线网络的有效部署。此外，毫米波网络具有许多属性，可以使用动态频谱访问（DSA）具有认知无线电的动态频谱访问（DSA）为有希望的有希望的方法，可以根据需求有效地部署异质网络，以共享此广阔的频谱。*** ***因此，研究计划将提供和分析MAC技术，以使多个无线通信网络中的多个设备具有各种服务要求和功能，以有效地共享广泛的毫米波谱。更具体地说，考虑使用定向天线的传感技术，将设计用于异质网络的动态频谱分配算法，并适应毫米波通信的现实，以及用于异质多频段多频段的MAC协议将提出和分析配备方向天线，最好与行业采用的网络架构兼容。优化工具，启发式算法和模拟工具将在这项工作中用于实现这些目标。***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适应，并且尚未考虑考虑广阔的毫米波谱的特殊性。因此，预计拟议的研究项目将为毫米无线网络的不断增长的领域产生重大的研究贡献，这是预测将来提供额外无线容量的主要方法。这些结果将引起无线服务提供商，设备制造商，标准化组织和研究社区的关注。因此，它应该有助于在未来的高速无线网络中成功整合认知毫米波收音机和定向天线技术。**
