Optimized deployment of drone base station to improve user experience in cellular networks

Deployment of Drone Base Stations for Cellular Communication Without Apriori User Distribution Information

“…[17] presented a statistical generic air-to-ground RF propagation model for the drone-BS cell, facilitate the formulation of modeling problems of cellular networks with drone-BSs. The control problems of drone-BSs previously studied in, e.g., [2,4,[18][19][20][21][22], are related to the 2D or 3D placement of drone-BSs. Where the objectives are to improve the coverage and power efficiency, maximizing the revenue and minimize the interference of drone-BSs.…”

“…Whereas the location information of network users is often unavailable, especially in the disaster area. [22] optimized the deployment of single and multiple drone-BSs to improve user experience in cellular networks based on greedy algorithms. The paper innovatively considered the inner drone distance constraint and drones' battery constraint during the optimization.…”

“…The paper innovatively considered the inner drone distance constraint and drones' battery constraint during the optimization. The area of interest considered in [22] is the urban area that can be described by a street graph with apriori MS density function that is reflecting the traffic demand at certain positions on the street. MSs are assumed to be located near streets.…”

Optimal Deployment of Drone Base Stations for Cellular Communication by Network-based Localization

“…BS, their exact locations cannot be acquired by the cellular network. [7] formulated a series of single and multiple drone-BSs deployment problems and proved that they are NP-hard. Several greedy algorithms were designed to solve the proposed problems.…”

“…Besides, the 2D projections of drone-BSs are restricted to streets to avoid collision with buildings, and MSs to be served are assumed to be located near streets. [7] innovatively considered drone-BSs' battery constraints and inner drone distance constraint during optimizations. In our paper, the operating area of drone-BSs is not limited to urban areas, and MSs are not necessarily to be located near streets.…”
