Query: Backhaul-Aware Optimization of UAV Base Station Location and Bandwidth
  Allocation for Profit Maximization   Unmanned Aerial Vehicle Base Stations (UAVBSs) are envisioned to be an
integral component of the next generation Wireless Communications Networks
(WCNs) by dynamically moving the supply towards the demand. A significant
drawback of the state-of-the-art have been designing a WCN in which the
service-oriented performance measures (e.g., throughput) are optimized without
considering different relevant decisions such as determining the location and
allocating the resources, jointly. In this study, we address the UAVBS location
and bandwidth allocation problems together to optimize the total network
profit. In particular, a Mixed-Integer Non-Linear Programming (MINLP)
formulation is developed, in which the location of a single UAVBS and bandwidth
allocations to users are jointly determined. The objective is to maximize the
total profit without exceeding the backhaul and access capacities. The profit
gained from a specific user is assumed to be a piecewise-linear function of the
provided data rate level, where higher data rate levels would yield higher
profit. Due to high complexity of the MINLP, we propose an efficient heuristic
algorithm with lower computational complexity. We show that, when the UAVBS
location is determined, the resource allocation problem can be reduced to a
Multidimensional Binary Knapsack Problem (MBKP), which can be solved in
pseudo-polynomial time. To exploit this structure, the optimal bandwidth
allocations are determined by solving several MBKPs in a search algorithm. We
test the performance of our algorithm with two heuristics and with the MINLP
model solved by a commercial solver. Our numerical results show that the
proposed algorithm outperforms the alternative solution approaches and would be
a promising tool to improve the total network profit.
