Medium access control protocols for millimeter wave cognitive networks with directional antennas

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。

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.
