Summary: Unmanned aerial vehicles, especially multirotors, are widely used for aerial sensing and remote inspection in large industrial facilities. To overcome the limitation of limited communication range, relaying UAVs can be placed between the source UAV and the control station to create a line of communication links. This study focuses on using WiFi network technology and proposes a fully distributed method for determining the optimal placement of relaying UAVs.

Summary: Distributed denial of service (DDoS) attacks have been prevalent on the Internet for decades and continue to grow in size, frequency, and duration. The new network paradigm, Software-defined networking (SDN), is also vulnerable to DDoS attacks. However, the data plane visibility of SDN provides new opportunities to defend against DDoS attacks in the cloud computing environment.

Summary: This research focuses on the deployment of UAVs over a predefined area to serve ground users, considering the interference between UAVs due to network heterogeneity. By defining a potential game and applying a game-theoretic learning algorithm, the authors successfully solved the user-UAV association and location problem optimally. They designed an efficient greedy algorithm based on submodular features and proposed a heuristic greedy algorithm, both achieving significant performance in a few iterations.

Summary: This paper investigates a mobile relaying system assisted by an unmanned aerial vehicle with a finite buffer size, considering a dual-hop mixed FSO/RF relaying system. By addressing trajectory design of the UAV relay node taking into account transmission rate imbalance between RF and FSO links, the study aims to achieve maximum data throughput at the ground user terminal. A proposed iterative algorithm effectively obtains locally optimal solutions and presents trajectory results under atmospheric conditions, buffer size, and delay requirements, leading to 223.33% throughput gain compared to conventional static relaying schemes.

Summary: This paper proposes a visual positioning algorithm called AGCosPlace based on image retrieval, which leverages the Transformer architecture to improve performance and overcome the limitations of unknown relative poses and intrinsics of drone cameras. The algorithm involves encoding the feature map of the backbone with attention mechanisms, multi-layer perceptron coding, and a graph network module for better contextual information aggregation. Experimental results demonstrate that the proposed algorithm achieves notable improvements in four evaluation metrics and can effectively be used for UAV visual positioning tasks.
