Backhaul-Aware Drone Base Station Placement and Resource Management for Fso Based Drone Assisted Mobile Networks

In drone assisted mobile networks, drones mounted small cell base stations (DBSs) are responsively and flexibly deployed over any Places of Interest (PoI), such as sporadic hotspots disaster-struck areas, where the existing network infrastructure is unable to provide wireless coverage. Here, a DBS relay node traffic between nearby macro station (MBS) users. addition, Free-space optics (FSO) applied backhauling solution significantly increase capacity backhaul link an MBS in network. Most placement solutions assume FSO based provides sufficient capacity, which may not be true, especially when placed far away from (e.g., > 10 km areas) or bad weather condition. this paper, we formulate problem jointly optimize bandwidth allocation by considering constraint. A Backhaul awaRe allOcAtion (BROAD) algorithm designed efficiently solve problem, performance demonstrated via extensive simulations.
