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.
Abstract:
Provided is an apparatus and method for detecting a traffic flooding attack and conducting an in-depth analysis using data mining that may rapidly detect a distributed denial of service (DDoS) attack, for example, a traffic flooding attack, developed more variously and firmly from a denial of service (DoS) attack, perform an attack type classification, and conduct a semantic analysis with respect to the attack. The apparatus and method may support a system operation and provide a more stable service, by rapidly detecting a traffic flooding attack, classifying a type of the attack, and conducting a semantic analysis based on a prediction and analysis scheme of data mining.
Abstract:
Provided is a method for translating connectivity of an entity to a Web. The method for translating an entity to things based on a Web includes dividing the individual entity into a virtualization part that declares request and control with respect to things and a specialization part that specializes a request with respect to things and removes a restriction of the individual entity, and translating the same, and defining a mapping rule between a characteristic of the individual entity and a connectivity technology supported by a Web in the specialization part.
Abstract:
A resource sharing apparatus which allows a first terminal and a second terminal to share a resource includes a virtual node generating unit which generates a virtual node corresponding to the second terminal in a storing space in the first terminal, and a sharing control unit which transmits sharing data to the second terminal through the virtual node, if information on at least one resource which is permitted to be shared with the second terminal, among the resources of the first terminal, is generated, deleted, or changed.
Abstract:
According to an aspect of the present disclosure, there is provided a method of implementing a radio access network (RAN)-core convergence mobile network based on cloud native, the method comprising: extending a first open RAN base station including an open RAN-central unit-control plane (O-CU-CP) and a cloud-based second open RAN base station having converged functions of a core network into a service-based architecture (SBA) of the core network; authenticating and accepting user equipment (UE) through the extended SBA; and extending the UE to the SBA through radio resource setting and protocol data unit (PDU) session establishment.
Abstract:
An a logistics information processing server includes a data processor configured to receive environment sensing data collected from at least one environmental sensor disposed in a cargo storage device in which at least one cargo is stored and cargo related information collected from a cargo tag attached to the at least one cargo, and to perform processing by classifying the environment sensing data and the cargo related data into cargo storage environment data, cargo information, and transportation environment information according to data attributes; and a logistics trust index generator configured to generate a logistics trust index indicating a degree of influence exerted on the quality of the cargo from the cargo storage environment data, cargo information, and transportation environment information output by the data processor.
Abstract:
Disclosed are a high speed wide range RFID tag capable of improving a data transmission speed and a recognition distance between an RFID tag and an RFID reader by controlling a reflected power as multi levels through adjustment of a reflection coefficient in the RFID tag, and a method of controlling the same. The RFID tag includes a data converting unit configured to convert stored RFID serial tag data into a number of multi-level parallel data according to a request of an RFID reader, a reflection coefficient adjusting unit configured to generate a plurality of reflection coefficients corresponding to a number of the converted parallel data, and a transmitting unit configured to transmit a number of the multi-level parallel data according to the generated plurality of tag reflection coefficients through an antenna to the RFID reader.
Abstract:
A method for providing a traffic safety service of a traffic safety service server communicating with a client terminal includes: receiving sensor data of each sensor from the client terminal; classifying the sensor data into data according to at least one specific time slot for each sensor and calculating a safety score of each of the at least time slot; calculating an average of the safety scores of the at least time slot and calculating a safety score for each sensor, and calculating a safety index on the basis of the safety score for each sensor and a weight assigned to each sensor.
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.
