Abstract: 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.

Abstract: Provided is a Raman scattering measurement apparatus including a light source which emits light to smoke particles, a filter configured to block light which is incident to the smoke particles and passes through the particle and to allow Raman scattered light to pass therethrough, and a photodetector which detects the Raman scattered light passing through the filter in order to distinguish fire smoke generated due to a true fire from non-fire smoke generated due to daily life or industrial activity. The present invention also provides a fire determination apparatus including a unit which reads a Raman shift from Raman scattered light detected by the photodetector of the Raman scattering measurement apparatus, estimates a smoke component from the read Raman shift, and determines fire/non-fire from the estimated smoke component and a method thereof.

Abstract: Provided are an apparatus and method for performing routing for multi-hop communication. A mobile ad-hoc routing apparatus includes a control information manager configured to generate control information for managing a topology in a mobile ad-hoc network, a control information transceiver configured to transmit the control information or information for generating the control information to other nodes and receives control information of the other nodes or information for generating the control information from the other nodes, a data path manager configured to set a path for transmitting and receiving data using the generated control information and the received control information or the information for generating the control information, and a data transceiver configured to transmit and receive the data through the set path. The path for transmitting and receiving the data and a path for transmitting and receiving the control information use channels that are physically different from each other.
