There is provided a method performed by a system for obtaining a relative location of an anchor-free UWB-based node. The method includes obtaining relative distances between a plurality of nodes based on UWB sensor values between the nodes, constructing a relative coordinate system having a center node of the plurality of nodes as a base, and calculating coordinate values of other nodes in the relative coordinate system. The constructing of the relative coordinate system having the center node of the plurality of nodes as a base includes constructing the relative coordinate system based on a relative distance between the center node and another node and absolute values of y axis values.

System and method for obtaining relative location of anchor-free UWB-based node

Disclosed is a communication method for transmitting a packet in an environment where a plurality of networks or communication schemes coexist. A communication method according to an exemplary embodiment of the present disclosure may comprise receiving at least one observation value or reward-related information for network states; determining a transmission control protocol (TCP) congestion window size based on the at least one observation value or the reward-related information; and transmitting a packet according to the determined TCP congestion window size.
