Abstract: Disclosed is a method of controlling a fleet of drones. A method in which a ground control station (GCS) controls a fleet of drones includes registering, by the GCS which is located on the ground, stores information about the drones, and controls the drones, all the drones constituting the fleet in a fleet list, configuring the fleet by synchronizing a physical position and a logical position for each of all the registered drones, controlling a form of the fleet based on a mission of the fleet or a peripheral environment having an influence on a flight of the fleet, and maintaining the fleet by immediately reflecting inclusion or departure in fleet information when the drone constituting the fleet is incorporated into or departs from the fleet.

Abstract: Disclosed is a method of measuring a state of a drone. The method of measuring the state of the drone in a state in which a plurality of drones and a ground control station (GCS) are connected through a wireless network includes measuring, by a first drone, its own state based on collected information, requesting, by the first drone, a second drone or the GCS connected through the network to provide correction information and receiving the correction information from the second drone or the GCS, and comparing, by the first drone, information about the measured state with the received correction information, analyzing an error, and correcting the error.

Abstract: The present disclosure relates to change a network adaptively for an electronic device. According to various embodiments, the electronic device may comprise performing data communication with at least one electronic device over a first communication network, detecting a change associated with a state of network based on at least one of a link connection state with the at least one electronic device and a feature of an application executed in the electronic device, and performing data communication with the at least one electronic device over a second communication network. The electronic device can configure the network according to a state of overall network and control/manage elements of the overall network.

Abstract: The present invention relates to a method for controlling hand-over in a drone network.

Abstract: An image encoding apparatus and method and an image decoding apparatus and method are disclosed. The image encoding method may include extracting a ROI from an input image, determining a compression rate of a remaining region excluding the ROI of the image based on a network state between the image transmitting apparatus and the image receiving apparatus, and encoding the remaining region based on the compression rate.

Abstract: A method and an electronic device for controlling a topology are provided. The method includes forming a star topology by directly connecting the electronic device to at least one node, and transmitting and receiving signals with neighboring nodes including the at least one node and determining whether to form the star topology or an extended star topology with the neighboring nodes based on a result of the transmitting and receiving, wherein the star topology is a topology in which the electronic device is directly connected to the neighboring nodes, and wherein the extended star topology is a topology in which the electronic device is directly connected to the neighboring nodes via an already connected node.
