Abstract: A network connecting method includes: storing, by a server, a data table that matches a first information on an access point (AP) with a second information related to a beacon, wherein the access point (AP) and the beacon are configured to perform short-range wireless communications of different standards; transmitting, by the beacon, a beacon message on basis of an authentication information; obtaining, by a terminal, the authentication information based on the beacon message; transmitting, by the terminal, a request message including the authentication information to the server through long-range wireless communication; obtaining, by the server, based on the data table, an access information corresponding to the authentication information transmitted from the terminal; transmitting a response message including the access information to the terminal; and accessing, by the terminal that receives the response message, the AP by using the access information.

Abstract: Disclosed herein are a virtual controller client mobile terminal-based virtual game controller and a remote control system using the same. The remote control system includes a virtual controller server and a virtual controller client. The virtual controller server generates button setting information including mapping relationship between key inputs and virtual input messages, transfers the button setting information, extracts a key input from a virtual input message, and provides the key input to the application. The virtual controller client specifies an arrangement and attributes of virtual buttons based on the button setting information, generates a virtual button screen on the touch screen of the mobile terminal, generates a touch input message based on touch event objects generated based on touch signals for regions corresponding to the virtual buttons, and converts the touch input message into a virtual input message and outputs the virtual input message.

The remote control system includes a virtual controller server and a virtual controller client. The virtual controller server generates button setting information including mapping relationship between key inputs and virtual input messages, transfers the button setting M information, extracts a key input from a virtual input message, and provides the key input to the application. The virtual controller client specifies an arrangement and attributes of virtual buttons based on the button setting information, generates a virtual button screen on the touch screen of the mobile terminal, generates a touch input message based on touch event objects generated based on touch signals for regions corresponding to the virtual buttons, and converts the touch input message into a virtual input message and outputs the virtual input message.

Abstract: Disclosed herein are a method of controlling Hierarchical Mobile IPv6 (HMIPv6) network-based handover and an Access Router (AR) and Mobile Node (MN) therefor. The method include the steps of a first AR, to which a MN is connected, receiving an L3 handover initiation message, including a Media Access Control (MAC) address of the MN and the ID of a target Base Station (BS); the first AR creating a Local Care-of Address (LCoA) based on the MAC address of the MN and the ID of the target BS, and performing Binding Update (BU) on a Mobility Anchor Point (MAP) using the created LCoA; when an L2 handover completion message is received from the target BS of the MN, a second AR creating a second LCoA and transmitting the second LCoA to the MN; and the MN receiving the second LCoA from the second AR and configuring the received second LCoA as its own LCoA.

Abstract: Disclosed herein are a sensor network control method for data path establishment and recovery and a sensor network therefor. The sensor network control method includes the steps of (a) the sink node or a first sensor node creating an interest message, including information about a hop count between itself and the sink node, and transmitting the interest message to one or more neighboring nodes; (b) a second sensor node, which has received the interest message, creating a routing table using the hop count information of the interest message and information about the node having transmitted the interest message, (c) the second sensor node determining a data transmission path for data transmission to the sink node using the routing table; and (d) the second sensor node transmitting an interest message, including information about a hop count between itself and the sink node to at least one neighboring node.
