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

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，使得使用认知无线电的动态频谱接入(DSA)操作成为一种有前途的方法，可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。

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.
