Abstract:
PURPOSE: An apparatus for transmitting a node search message and a method thereof are provided to schedule node search message transmission among nodes independently, in order to exchange the required node search message efficiently. CONSTITUTION: A discovery window slot (DWS) calculation part (220) generates slot information for a search window of a search frame in a prior round by using time slot information. A discovery window (DW) size determining part (230) determines the size of the search window in the current round by using the slot information for the search window. A DWS selection part (240) selects a DWS to assign a node discovery message (NDM) to transmit in the current round on the basis of the size of the search window. An NDM processing part (250) transmits the NDM in the time corresponding to the DWS.

Abstract:
PURPOSE: An air patrol system using an unmanned aerial vehicle and a method for the same are provided to remotely monitor the existence of the generation an abnormal state in a monitoring target area at a ground control indicator in a safe area. CONSTITUTION: An air patrol method using an unmanned aerial vehicle is as follows. Image data with respect to a POI(Point Of Interest) which is a target of a patrol is obtained by a plurality of unmanned aerial vehicles(100). The obtained image data of the POI is transmitted to a ground control indicator(200). The ground control indicator analyzes the image data of the POI transmitted by the unmanned aerial vehicles, thereby monitoring the existence of the presence of abnormal objects in the POI. When the abnormal objects are existed in the POI, flight control signals are transmitted to the unmanned aerial vehicle transmitted the image data of the abnormal objects so that the aerial vehicle traces the abnormal objects and transmits the image data thereof to the ground control indicator.
Abstract:
PURPOSE: A QoS(Quality of Service) support device in middleware for a data distribution service and a method thereof are provided to preferentially process a QoS policy having higher priority by checking the compatibility and consistency of QoS policy sets and grouping QoS policies having correlations. CONSTITUTION: A QoS policy analyzing unit(300) extracts a QoS policy set related to publication and subscription set in DCPS(Data Centric Publish Subscribe) to analyze QoS policies. A QoS policy management unit(400) determines the consistency of the QoS policies of a data distribution service and negotiates for the QoS policies for the communication of the data distribution service. A QoS policy processing unit(500) processes the QoS policies of the data distribution service. The QoS policy management unit includes a QoS policy consistency checking unit determining the consistency of the QoS policies.

Abstract:
PURPOSE: A method for improving fuel efficiency of a vehicle of driving environment is provided to reflect lane condition information and road information. CONSTITUTION: A method for improving fuel efficiency of a vehicle of driving environment comprises: a step of calculating the difference of current power and changed power using collected one or more environmental information; a step of comparing the calculated difference with a standard value; and a step of controlling fuel consumption of the vehicle according to the comparison result.
