My colleagues were always kind to me and my directors always had a great understanding to allocate time for my PhD study. Fourthly, I would also like to acknowledge that BAP Unit of Istanbul Technical University supports my thesis with a project identified by the number: 41757. Lastly and foremost, I would like to thank my lovely family, especially to my wife Müge ÖZÇEVİK, her parents, my sister and my parents. I always felt their unending support in difficult times and I owed all of my achievements to them. In definite, I could not have achieved my current level of success without their support. Thanks for all.

“…As ANs move, RNs need to move as well and it is desirable to move them a minimum amount to re-establish the topology as quickly as possible, e.g., we should determine the instantaneous speeds of all RNs during the run time to maintain the network a specified level of connectivity with a minimum total movement of existing RNs. OUYANG et al [13] proposed an optimal design for UAV path planning to guarantee the connectivity in the scenario where a UAV is used as relay between a mobile access point and a fixed base station. However, the proposed method [13] cannot guarantee a certain level connectivity for a network formed by multiple mobile terminal nodes.…”

As a new sort of mobile ad hoc network (MANET), aeronautical ad hoc network (AANET) has fleet-moving airborne nodes (ANs) and suffers from frequent network partitioning due to the rapid-changing topology. In this work, the additional relay nodes (RNs) is employed to repair the network and maintain connectivity in AANET. As ANs move, RNs need to move as well in order to re-establish the topology as quickly as possible. The network model and problem definition are firstly given, and then an online approach for RNs' movement control is presented to make ANs achieve certain connectivity requirement during run time. By defining the minimum cost feasible moving matrix (MCFM), a fast algorithm is proposed for RNs' movement control problem. Simulations demonstrate that the proposed algorithm outperforms other control approaches in the highly-dynamic environment and is of great potential to be applied in AANET.

“…Under the condition of modern information warfare, unmanned aerial vehicles (UAVs) possessing the capacity of situation awareness, independent decision-making and cooperative attack, have been widely used. UAVs can take the advantage of agile and flexible tactics, strong continuous combat capacity and low life cycle cost, to complete combat mission under the extreme miserable combat environment [1]. However, because the intelligent level of UAVs is not high, it is hard for UAVs to cope with the battlefield environment with high uncertainty and strong emergent.…”

Aiming at the optimal placement of communication relay nodes (OPCRN) problem in manned/unmanned aerial vehicle cooperative engagement system, this paper designed a kind of fully connected broadband backbone communication topology. Firstly, problem description of OPCRN was given. Secondly, based on problem analysis, the element attributes and decision variables were defined, and a bi-level programming model including physical layer and logical layer was established. Thirdly, a hierarchical artificial bee colony (HABC) algorithm was adopted to solve the model. Finally, multiple sets of simulation experiments were carried out to prove the effectiveness and superiority of the algorithm.
