Abstract:
PURPOSE: A method and a device for arranging relay nodes, and a computer recordable medium thereof are provided to efficiently and rapidly calculate an arrangement location of a relay node. CONSTITUTION: A memory(230) stores location information of a sensor node included in a list of sensor nodes to be connected and a relay node included in a list of arranged relay nodes. A control unit(220) performs a relay node arrangement method using information stored in the memory. A data receiving unit(240) receives information related to the sensor nodes included in the list of the sensor nodes which will be connected.
Abstract:
PURPOSE: A method for assigning a family-based address in a wireless sensor network, and a method for setting a hierarchical routing path using the same are provided to assign an address of a child node to which a parent address is reflected by enabling the parent node to respond to an address assigning request of a child node, thereby easily setting a routing path. CONSTITUTION: If address assignment is requested from a node, the number of maximum child nodes is compared with the number of current child nodes(S105,S110). If the number of current child nodes is the same as the number of maximum child nodes, address assignment is rejected(S115,S120). If the number of current child nodes is smaller than the number of maximum child nodes, addresses of childe nodes are assigned.
Abstract:
PURPOSE: A multiple router IP-USN(Ubiquitous Sensor Network) and a communication method thereof are provided to have at least one router, thereby enabling internal sensor nodes to communicate each other through the router. CONSTITUTION: Sensor nodes(21~25,31~34,41~45) respectively designate routers as default routers. The sensor nodes designate closest routers among the routers as default routers. The sensor nodes communicate with an external network through the default routers.
Abstract:
PURPOSE: An address assigning method for hierarchical routing in a low power wireless personal area network and a packet transmitting method are provided to transmit a packet using hierarchical routing even though a location of a mobile node moves. CONSTITUTION: If a node is a mobile node, the node inputs its address to a departure address field and a destination address field(S10,S20). If the node is a fixed node, the node determines whether a destination node is a mobile node(S40). If the destination node is a mobile node, the node searches whether the node has an address bundle of the destination node and its undertaking node(S50).
Abstract:
PURPOSE: A method of operating a directory proxy agent in a low power wireless personal area network, a method of searching for specific service information, and a directory proxy agent performing the same are provided to operate a direction proxy agent, thereby enabling a user agent to efficiently search for desired service information. CONSTITUTION: A service registration request message is advertised to peripheral nodes. The peripheral nodes include at least user agent and at least one service agent(2120). An updated service information list is transmitted to a directory agent(2300) and another directory proxy agent(2110).
Abstract:
PURPOSE: A method for connecting an IP-based USN(Ubiquitous Sensor Network) with an existing IP network is provided to enable sensor nodes in an IP-based USN system to have intrinsic IP addresses, thereby enabling a user to obtain desired information and service from any external network. CONSTITUTION: Intrinsic IP addresses are respectively assigned to sensor nodes(S110). The sensor nodes broadcast their location information. An IP-USN router stores the broadcast location information in its own table. The IP-USN router broadcasts its own existence information to update the location information stored in the table.
Abstract:
복수의 사람에 의하여 공동으로 사용되는 물건의 점유 상태를 관리하는 방법은 카드로부터 카드 아이디를 얻는 단계, 상기 카드 아이디가 유효한 경우에는, 다수의 사람에 의하여 공동으로 사용되는 물건의 점유 상태를 포함하는 물건 점유 상태 테이블을 전송하는 단계 및 상기 물건 점유 상태 테이블에 포함된 적어도 하나의 물건 중 점유되지 않은 물건에 상응하는 물건 아이디를 입력받아 상기 입력받은 물건 아이디에 상응하는 물건의 점유 상태를 설정하는 단계를 포함한다. 따라서 복수의 사람에 의하여 공동으로 사용되는 물건의 점유 상태를 체크하여 효율적으로 물건의 점유 상태를 관리할 수 있다.
Abstract:
A robot game system is provided to inform a state of a robot by displaying changed energy information in graphical, and to generate control data according to operation of a user conveniently. A robot game system(100) includes a remote controlling part(110), a robot(120), and a robot status display part(150). The remote controlling part transmits generated control data after generating the control data. The robot performs a combat based on the transferred control data. The robot sends the robot status information. The robot status display part displays the received robot status information.
Abstract:
A method capable of easily finding out a place registered by a user is provided to store a position ID into a card or a card ID and position ID into a server by reading of a place by a location register. In a method capable of easily finding out a place registered by a user, an ID is read out from a card by the control of a location registor(220), and a location ID of the location registor is written into the card(S420). The location ID is obtained from the card by the control of a location display unit(S430). The location of the location registor registered by the card is displayed(S440).
Abstract:
A sensor node is provided to easily perform the sensor removal task and sensor change operation by forming the structure of exposing the sensor inserted into the sensor mounting portion. The various kinds of sensors(300) is installed to collect the various information in the sensor mounting portion(110). The sensor mounting portion has the structure of being exposed to outside. The sensor is easily mounted to the sensor mounting portion without the task separating the housing(100). The cover(200) is used in order to cover the upper side of the housing. The cover is manufactured to the square plate shape or the dome form. The display unit(130) showing the operating state of sensor is formed in one side of the sensor housing.
