The present invention relates to a sensor network, and more particularly, to a device and method for managing sensor nodes, in which with respect to predictable events and unpredictable events detected by sensors, the predictable events can be managed as existing policies and the unpredictable events can be managed by receiving policies for the unpredictable events from peripheral sensor nodes or peripheral sensor networks, i.e., both predicted events and unpredicted events can be intelligently managed. According to the method device for managing events detected by sensor nodes according to the present invention the present invention, in the case where unpredictable events are detected, policies for the detected unpredictable events received automatically from peripheral sensor nodes or peripheral sensor networks, so that both predictable and unpredictable events can be managed. Each time unpredictable events are detected, new policies for the detected unpredictable events are automatically generated, so that a manager does not need to update the policies for the unpredictable events every time. In addition, since both predictable and unpredictable events can be managed, the event management method of the present invention can be widely used in a variety of application fields requiring stability and accuracy.

The present invention relates to a method of controlling access to a wireless channel in a wireless communication system, and more particularly, to such a method of controlling wireless channel access, in which it is determined whether or not peripheral communication nodes are ones interrupting main communication between communication nodes being activated, and if it is determined that the peripheral communication nodes are ones which does not interrupt the main communication, they gain access to a wireless channel so as to perform parallel communication with respect to the main communication. The wireless channel access control method according to the present invention determines whether or not peripheral communication nodes actually interrupt main communication, and if it is determined that the peripheral communication nodes are ones which does not interrupt the main communication, they gain access to a wireless channel so as to perform parallel communication with respect to the main communication, thereby efficiently utilizing a limited wireless channel resource.

A method is provided for supporting mobility of a Mobile Node (MN) in a multi-hop Internet Protocol (IP) network, in which an MN that has moved from a source Personal Area Network (PAN) to a target PAN, sends a Router Solicitation (RS) message with an option for requesting its profile to a gateway of the target PAN, and receives a Router Advertisement (RA) message from the gateway in response to the RS message. The RA message includes a home prefix of the MN as the requested profile. The method supports mobility of MNs, enables unicast communication, and facilitates efficient use of the network.

The present invention relates to a method of analyzing user's behaviors based on a moving pattern of the user, and more particularly, to a method of operating a user information-providing server, in which behaviors of the user can be analyzed by providing information on user's emotion which varies depending on a moving pattern of the user, together with the moving pattern of the user, to the user or a counterpart. The inventive user information-providing server operating method provides information on user's emotion inferred using user's biological information obtained from a variety of sensors, information on a place where the user is positioned, and information on a counterpart, so that user's behaviors applicable to various fields can be accurately determined based on simple user's moving patterns and user information varying depending on the user's moving pattern. In addition, user's behaviors varying depending on the obtained counterpart information can be determined.

Provided are a method for emotion communication to share a user's emotions between an emotion signal sensing device and an emotion service providing device. The method for emotion communication includes: the emotion signal sensing device's sensing biological and environmental information of the user and generating an emotion signal and emotion information of the user based on the biological and environmental information; establishing an emotion communication connection with the emotion service providing device; transmitting the emotion signal and the emotion information to the emotion service providing device by the emotion communication connection establishment; and breaking the connection with the emotion service providing device

Provided is a method for tracing-back an IP using marking information of a router stored on a hop-by-hop option header, which is one of IPv6 extension headers. According to the method, an attack made by an attacker is detected on the IPv6 network. If the attack is detected, information stored on a hop-by-hop option header of a packet received through the IPv6 network and marked by a router through which the packet has passed is extracted. After that, a reception path of the received packet is reconstructed and an IP of the attacker is back-traced using the extracted marking information.

A mobility management system and method is provided for efficiently support mobility to an IPv6 based LoWpan. The mobility management method for Internet Protocol version 6 (IPv6) based personal area network (PAN) moving with a mobile router according to the present invention includes detecting, at a mobile terminal, movement of the mobile router; determining whether the movement is an intra-network movement or an inter-network movement, transmitting, when the movement is an intra-network movement, a neighbor discovery request message to a gateway of a currently attached network and receiving a neighbor discovery response message containing a temporary address transmitted by the gateway in response to the neighbor discovery request message. When the movement is an inter-network movement, the gateway receives the binding acknowledgement message from a home agent and establishes a bidirectional tunnel with the home agent.

A method for transmitting content in a content centric network. The method provides a mobile router with information regarding the content transmission path between a connection router and a mobile terminal while the mobile terminal moves from the current connection router to the mobile router, and enables the mobile router and routers adjacent to the mobile router to transmit a content request message only to the path router included in the transmission path from among the adjacent routers based on the transmission path information, thus reducing loads to a network and quickly transmitting a request content to the mobile terminal.
