5G+ systems expect enhancement in data rate and coverage area under limited\npower constraint. Such requirements can be fulfilled by the densification of\nsmall cells (SCs). However, a major challenge is the management of fronthaul\nlinks connected with an ultra dense network of SCs. A cost effective and\nscalable idea of using network flying platforms (NFPs) is employed here, where\nthe NFPs are used as fronthaul hubs that connect the SCs to the core network.\nThe association problem of NFPs and SCs is formulated considering a number of\npractical constraints such as backhaul data rate limit, maximum supported links\nand bandwidth by NFPs and quality of service requirement of the system. The\nnetwork centric case of the system is considered that aims to maximize the\nnumber of associated SCs without any biasing, i.e., no preference for high\npriority SCs. Then, two new efficient greedy algorithms are designed to solve\nthe presented association problem. Numerical results show a favorable\nperformance of our proposed methods in comparison to exhaustive search.\n
