Abstract:
A method of transmitting and receiving a data frame supporting a video MAC protocol and a system thereof are provided to use contents having error partially, thereby reducing waste of network resources due to contents retransmission. A video MAC(Media Access Control) support terminal determines whether a video MAC protocol is supported(S210). A video MAC data frame is received so that the video MAC support terminal determines whether error exists in a header. If the error does not exist in the header, the received video MAC data frame is provided to a user without respect to that error exists in a body(S240).

Abstract:
PURPOSE: A heterogeneous sensor network integration support device and a method thereof are provided to deliver converted data to a sensor-integrated system by collecting sensor data from heterogeneous sensor networks. CONSTITUTION: A sensor-integrated system protocol and interface selecting unit(130) selects an interface and a protocol of a sensor-integrated system to which sensor data is delivered. An adaptor generating unit(150) generates an adaptor by using a model. The model is generated by modeling a sensor data collection process, a sensor data conversion process, and a sensor data delivery process.

Abstract:
PURPOSE: A method for collecting sensing information using a sensor air node, the sensor air node therefor, and a base station thereof are provided to efficiently collect 3D sensing information in a wide area requiring sensor nodes according to time. CONSTITUTION: A sensor air node(110) moves along a predetermined movement trace. The sensor air nodes collect sensing information. A base station(130) analyzes the sensing information and the movement trace information. The base station generates an analysis result of the sensing information and movement trace change information. The base station transmits the analysis result and the movement trace change information to the sensor air nodes. The sensor air nodes change the movement trace based on the movement trace change information and the analysis result.

Abstract:
PURPOSE: A monitoring method and system thereof are provided to offer improved three dimensional location based service by embodying topology operation between three dimensional coordinates and a complex location. CONSTITUTION: A reception unit(121) receives measuring time and three dimensional coordinates of a terminal from one or more terminals. A transmission unit(123) notifies the loss of event generation to a monitoring center. A data storage unit(124) stores the generation conditions of the event, the measuring time, and the current three dimensional coordinates. A three dimensional coordinate calculation and control unit(122) uses the measuring time of the current three dimensional coordinates. The three dimensional coordinates calculation and control unit calculates a phase relationship between the three dimensional coordinates and a three dimensional section.
Abstract:
PURPOSE: A products purchase service providing device using social network is provided to offer reliable real-time mobile social shopping service by managing each commenter's reliability based on social network. CONSTITUTION: A public opinion request message processor(250) receives a reputation requesting message from a user terminal. The public reputation message processing unit processes the received message. A product information manager(220) connects to a social network in which the user is subscribed. The product information manager searches products which satisfies the product qualification information. A product evaluation information manager(230) collects evaluation comment of the social network subscribers.
Abstract:
PURPOSE: An event monitoring system with an agent unit which can determine accuracy of an event using a network camera and a method thereof are provided to share existing event information of a camera network around a network camera, thereby improving event accuracy such as motion sensing and object tracking. CONSTITUTION: An event monitoring system using a network camera comprises agent units(102,112,122,132). The agent units provide a protocol for transceiving data between devices by connecting to devices within the monitoring system. When the agent unit receives an event generated from the network camera, verification event transmission for the event is requested to a neighbor network device connected by a wire/wireless network in the monitoring system. The agent unit determines accuracy of the generated event based on verification event information.
