摘要： 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.

摘要： 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.
