Provided is a method of managing a non-IP sensor network using a simple network management protocol (SNMP), and more particularly, a method of remotely managing a non-IP based sensor network, such as Zigbee, from the Internet of a sensor network manager.

There is provided a movement detection method of a mobile node in a DSMIP6 environment. The movement detection method includes performing neighbor unreachability detection in a network to which a mobile node moves, confirming network movement detection and simultaneously performing IPv4 address allocation when the neighbor unreachability detection fails, performing router discovery at the same time as the IPv4 address allocation, recognizing the movement detection into the IPv4 network when the IPv4 address allocation succeeds, and recognizing the movement detection into the IPv6 network when the router discovery and the IPv6 router discovery succeed. Therefore, the movement detection method can be useful to continuously perform operations as defined in a DSMIP6 specification so as to confirm whether the network to which the mobile node moves is an IPv6 network or an IPv4 network and detect movement to the confirmed network, and to perform a binding update in time.

Provided is an apparatus and method for preventing air baggage from getting lost using a radio frequency identification (RFID) system. The apparatus for preventing baggage from getting lost, change, or stolen in which a baggage tag storing baggage management information is attached to the baggage and a receipt tag storing the baggage management information is issued to a baggage owner, the apparatus includes: a tag reader reading the receipt tag and the baggage tag in a predetermined area; and a determiner determining whether the tag reader reads the receipt tag including the same baggage management information as the baggage management information of the baggage tag within a predetermined time before and after the tag reader reads the baggage tag. As a result, air baggage is quickly and exactly managed, costs is reduced, and foreign confidence of an airport is increased, thereby preventing baggage from getting lost and exchanged.

A method of transmitting a neighbor discovery protocol (NDP) message in an IEEE 802.16/Wibro network is provided. The method of transmitting an NDP message in a sub-network formed with access routers and a plurality of base stations connected to the access router through separate interfaces includes: a first base station transmitting a first NDP message received from a first terminal, to the access router; and the access router transmitting the first NDP message to the remaining base stations excluding the first base station. According to the method, a method of processing an NDP message in an environment having multiple base stations which cannot be considered under a conventional environment using a multicast connection ID (CID) can be improved, and problems that can occur when a IPv6 is introduced in an IEEE 802.16/Wibro network can be solved.
摘要:
Provided is a communication method between an IPv6 mobile node and an IPv4-based correspondent node in a mobile IPv6 (MIPv6) environment, and more particularly, a communication method which can keep communication between a mobile node in an IPv6-based network and a correspondent node in an IPv4-based network, although the mobile node, which communicates with the node in the IPv4-based network, moves to a foreign network. In order to support mobility between the both networks, a DSTM gateway (or DSTM TEP) corresponding to a DSTM border router processes a binding update request received from an IPv6 mobile node.
摘要:
The present invention provides a robust FBAR device and a simplified method of fabricating a FBAR device. FBAR device according to the present invention includes a membrane supporting layer between a substrate and a membrane layer, surrounding an air gap region. The membrane supporting layer supports the membrane layer to obtain a robust structure. Firstly, the method forms a sacrificial layer on the substrate, then a photoresist pattern is formed on air gap forming region at a top surface of the sacrificial layer, the method removes the sacrificial layer to form a sacrificial pattern by using the photoresist pattern as an etching mask. An insulating material then deposits on the substrate, the photoresist pattern is remove, and a membrane layer is formed on a top surface of the sacrificial layer and the insulating material layer. Finally, the method removes the sacrificial pattern to form an air gap.

A steam generator is provided that includes an external case having an opening that allows an internal space to communicate with an external environment. Additionally, the steam generator may be provided with a supplier that supplies water to the internal space, a heater provided to the opening to generate steam, an outlet pipe having a first side that communicates with the external environment to discharge steam, and a steam discharge controller provided to a second side of the outlet pipe to open/close the outlet pipe according to a presence or absence of a discharge of the steam.

A method of performing a handover is provided. The method of performing the handover includes: a mobile terminal transmitting an access stop message to a first Access Point (AP) when the mobile terminal moves from a first AP area to a second AP area; the first AP transmitting a handover start message to a first Mobility Access Gateway (MAG) corresponding to the first AP in response to the access stop message; the first MAG transmitting the handover start message to a Local Mobile Anchor (LMA); and the LMA performing a buffering of a data packet to be transmitted to the mobile terminal.
