Abstract:
Provided is a method for determining network link quality between a master station and slave stations in a wireless network system having a synchronous superframe structure. The method for determining link quality in a wireless network system includes determining whether the current station is a master or a slave, when the current station is a master, comparing a time value during which the latest packets were received from slaves and a maximum time value during which the slaves are not obliged to exchange packets with the master after accessing a network, and determining link quality between the slaves and the master according to the comparison result.
Abstract:
The present invention relates to a system and method for changing a wireless personal area network (WPAN) channel when the quality of communication is degraded due to a change of a wireless environment. The system according to the present invention includes slaves configured to transmit/receive data, and a master connected to the slaves and configured to obtain communication state information of the slaves and select an adjacent channel search slave from among the slaves according to the obtained communication state information of the slaves.
Abstract:
There are provided a method and a system for operating a metaverse platform, which operate to remember activities of patients with physical difficulties and memories of the deceased. According to an embodiment of the disclosure, a metaverse platforming operating system includes: a data collection unit configured to collect image and voice data of a user; a voice and image correction module configured to correct an image and a voice of the user by inputting the collected image and voice data to a trained AI model; an avatar generation module configured to generate a virtual avatar reflecting a facial image of the user in a metaverse, based on the corrected image; and an avatar action control module configured to control an action of the generated avatar according to an inputted input signal. Accordingly, patients, family, and acquaintances may smoothly communicate with patients with physical difficulties in a metaverse virtual world, and may remember memories of the deceased by communicating with the avatar of the deceased.
