A system, method, and apparatus are provided for establishing a wireless network connection between a mobile terminal and an electronic apparatus by using a near field communication network. At least one electronic apparatus is connected to the near field communication network. A mobile terminal is connected to the near field communication network, exchanges information with the at least one electronic apparatus for a wireless communication network connection through the connected near field communication network, and establishes the wireless communication network connection with the at least one electronic apparatus based on the exchanged information.

System, method and apparatus for wireless network connection using near field communication

A method and apparatus for communicating with a target device in a personal area network (PAN), when a multi-function remote controller (MRC) is outside the coverage area of the target device. The apparatus includes a proxy device which automatically forms a virtual PAN by setting up a pairing link with the target device to control the target device. Accordingly, a user may continuously control the target device irrespective of the location of the MRC.

Method and apparatus for remotely controlling consumer electronics device by using wireless personal area network

Provided is a wireless connection device including a selection information generating unit which generates selection information with respect to each external device of a plurality of external devices that transmitted signals for wireless connection; a selecting unit which compares the selection information regarding each external device of the plurality of external devices and selects an optimal device from among the plurality of external devices based on a result of the comparison; and a connection processing unit which establishes a wireless connection to a first external device, among the plurality of external devices, that first transmitted the signal for wireless connection, and, if the first external device is different from the optimal external device, terminates the wireless connection to the first external device and establishes a wireless connection to the optimal external device.

Method and apparatus for secure pairing in wireless communication

Heterogeneous protocol stacks are used in an approach including analyzing a destination network ID of data received by a shared, lower layer protocol stack, a data type field value, and/or whether any of the upper layer protocol stacks support broadcasting. An upper layer protocol stack is selected based on the results of the analysis. The received data is transmitted to the selected upper layer protocol stack. Accordingly, heterogeneous protocol stacks may be realized in one chip.

Method and apparatus for communication using heterogeneous protocols

A method of avoiding a channel interference in a single channel sensor network, includes periodically measuring an energy of a channel used by at least one node included in the sensor network; exchanging the measured energy of the channel with a neighbor node of the at least one node; receiving energy of all nodes of the sensor network and determining if there is an interference, by a coordinator node, which is a highest node of the at least one node; and when it is determined that there is an interference, switching a channel influenced by the interference to a channel which has been scanned by the coordinator node and is not influenced by the interference, thereby avoiding an influence of the interference.

A method and apparatus for authenticating a sensor node in a sensor network. The method for authenticating a sensor node by a first sink node in a sensor network includes receiving an authentication request using an authentication ticket from the sensor node, identifying a second sink node which has issued the authentication ticket, decoding the authentication ticket using a group key, which is previously stored in correspondence to the second sink node to confirm the validity of the authentication ticket, when the second sink node is included in a neighboring node list, normally processing authentication for the sensor node, generating an authentication ticket using a group key of the first sink node, and transmitting the generated authentication ticket to the sensor node.

A channel connection of a device that performs short range wireless communication is provided. If a public key that is broadcast by a specified device is received, the device encrypts its own UID (Unique Identifier) using the public key to transmit the encrypted UID to the specified device, transmits a pairing request to the specified device, and safely receives a key seed from the specified device using a security address included in a pairing device and the UID to form a security channel with the specified device.

Method and apparatus for forming security channel in short range communication

Disclosed a system and method for mutual authentication between a node and a sink in a sensor network. At least one sink periodically creates a neighboring sink list including information on at least one adjacent sink, and the sink requests node authentication to a base station when receiving an authentication request from the node and transmits its own neighboring sink list to the node when the node authentication has been completed. When the node moves and requests authentication to another sink, the another sink stores a neighboring sink list received from the node, determines if a node-authenticable sink exists in its own neighboring sink list according to the authentication request, and requests re-authentication of the node to the node-authenticable sink when the node-authenticable sink exists, so that re-authentication between the node and the sink is easily performed.
