In recent years, the widespread adoption of smartphones and IoT devices has driven an explosive increase in mobile traffic, degrading communication speeds. To accommodate mobile traffic efficiently, small cell deployment, where low-power small cells are deployed within a high-power macro cell to expand coverage and capacity, has proven effective. However, because mobile traffic fluctuates significantly by time and location, fixed small cell deployments suffer from low equipment utilization during off-peak times or in low-demand areas, such as office districts at night or residential areas during the day. To address this issue, moving small cells mounted on vehicles have been proposed, allowing flexible deployment according to temporal and spatial traffic variations. Although
conventional studies have demonstrated that moving small cells can improve throughput, they assumed an ideal wireless backhaul link between roadside units (RSUs) and small cells. In realistic environments, however, bandwidth limitations and radio interference on wireless backhauls must be considered, so the characteristics of moving small cells have not been fully evaluated. This report assumes millimeter-wave backhaul transmission between RSUs and mobile small cells and evaluates end-to-end throughput performance through computer simulations. |
