Abstract:
An operation method of a first apparatus for supporting disaster communications includes obtaining map information of a disaster area from a server; obtaining information on a location of the first apparatus, and obtaining environmental condition information of the first apparatus indicating a risk of an area to which the first apparatus belongs; obtaining information on a location and environmental condition information of a second apparatus located in the disaster area from the second apparatus; determining a disaster risk level indicating a risk level for each location in the disaster area based on the location and environmental condition information of the first apparatus and the location and environmental condition information of the second apparatus; and updating the map information by reflecting the disaster risk level.
Abstract:
A mobile ad-hoc routing apparatus includes a first communication module and a second communication module configured to transmit and receive data through a first communication band and a second communication band, respectively, a memory configured to store a program for transmitting and receiving the data, and a processor configured to execute the program stored in the memory, wherein when the program is executed, the processor receives first control information broadcast by one or more neighboring nodes via the first communication module and stores the first control information in the memory, wherein the first control information includes current position and communication status information of the neighboring node, the processor updates information on the neighboring node on the basis of the first control information, generates packet forwarding information which includes information on a node which currently allows packet data to be transmitted based on the updated information on the neighboring node, and stores the generated packet forwarding information in the memory, and the processor determines a subsequent node which allows the packet data to be transmitted to a destination node on the basis of the packet forwarding information and transmits the packet data to the subsequent node via the second communication module.

Abstract:
A method and apparatus for controlling a transmission signal for a disaster scene communication system. The method includes determining a type of a transmission message transmitted to a mobile terminal device by a control terminal device of the disaster scene communication system, determining a criticality level of the transmission message corresponding to the type of the transmission message, determining an initial distance between the control terminal device and the mobile terminal device by checking initial location information of the mobile terminal device, setting an initial transmission power in consideration of the criticality level of the transmission message corresponding to the type of the transmission message and the initial distance between the mobile terminal device and the control terminal device, and controlling a current transmission power based on the initial transmission power.
Abstract:
A system for managing a disaster based on a grid and an operating method of the system are disclosed. The operating method includes generating one or more models respectively corresponding to one or more sensors, acquiring and storing one or more of one or more pieces of sensing information sensed by the one or more sensors, event information determined based on the one or more pieces of sensing information, and status information of the one or more sensors, in the one or more models, based on multidimensional spatial information based on a grid on which the one or more sensors are disposed, information stored in the one or more models, and disaster information related to the multidimensional spatial information, creating grid-based data to monitor a disaster situation associated with the information stored in the one or more models and/or the multidimensional spatial information, and outputting the created grid-based data.
