论文摘要
为了提高容量并克服蜂窝无线网络的某些局限性,可以部署带有空中基站的无人机以协助陆地蜂窝无线网络。无人机的移动性允许灵活的网络重新配置适应动态流量和渠道条件。但是,这是以牺牲更多移交为代价的,因为即使静态用户也可能在无人机移动时会经历移交。在这封信中,我们为无人机基站网络的移交率和周时间(随后的两个移交之间的时间)提供了精确分析。我们还表明,在具有相同均值的不同速度分布中,当所有无人机基站以相同的速度移动时,切换率为最低。
To improve capacity and overcome some of the limitations of cellular wireless networks, drones with aerial base stations can be deployed to assist the terrestrial cellular wireless networks. The mobility of drones allows flexible network reconfiguration to adapt to dynamic traffic and channel conditions. However, this is achieved at the expense of more handovers since even a static user may experience a handover when the drones are mobile. In this letter, we provide an exact analysis of the handover rate and sojourn time (time between two subsequent handovers) for a network of drone base stations. We also show that among different speed distributions with the same mean, the handover rate is minimum when all drone base stations move with same speed.
