A method of supporting flow mobility of an MN is provided in an LMA. The LMA updates a BCE when a flow of the MN moves from a first MAG to a second MAG. The LMA sends a message for requesting binding registration of the flow to the second MAG, and sends a message for requesting binding de-registration of the flow to the first MAG.

A method of extending a routing protocol for supporting an M2M service in a wireless mesh basic service set (MBSS) is provided. A method of extending a routing protocol that sets a mesh station (M-STA) that is connected to a distribution system in M-STAB of an MBSS to a mesh gate, in which the mesh gate transmits a RANN message and a gate announcement message to the M-STA, in which the mesh gate receives a path request message from the M-STA, and in which the mesh gate stores a path from the mesh gate to the M-STA based on the received path request message is provided. Because an M2M service terminal can be connected to the M-STA, the M-STA receives data from an M2M service terminal and the received data is included in a proxy update message, and the proxy update message is transmitted to the mesh gate.

Provided is multi-channel and multi-interface mesh router and method of assigning a channel according to a fixed distribution scheme. The channel assignment method may configure a neighbor information table, a parent list, and a dependent list through exchanging of information between mesh routers, and may determine a channel assignment order based on the parent list and the dependent list and then assign a channel, beginning with a mesh router selected as a seed node, and sequentially transmit channel assignment information to mesh routers included in the dependent list.

Provided is a method of data transmission from an access router in a wireless mesh network. The method of data transmission includes: receiving, from a gateway, a broadcast message indicating that a connection to the external internet can be made; establishing a bi-directional path to the gateway;when a new node is connected to the access router, sending information about the new node to the gateway; if there is a data transmission in which a node located within the coverage area of the access router is a destination node, forwarding the data to the destination node.

In a network environment in which an endpoint identifier and a routing locator are separated from each other, a first router receives a data packet including an endpoint identifier of a first host and an endpoint identifier of a second host that is a communication target of the first host from the first host managed by the first router in order to convert a network address. A message requesting external address prefix information of the second host is transmitted to a second router managing the second host. In addition, the external address prefix information is received from the second router and a routing locator of the second host is generated by converting internal address prefix information of an endpoint identifier of the second host into the external address prefix information of the second host in the data packet.
摘要:
A method and system for supporting a seamless handover of a mobile node using a mobile Stream Control Transmission Protocol (mSCTP) to support the mobility of the mobile node are provided. In the method and system, a change in data link layer information, which occurs when the mobile node moves into a new sub-network, is detected and changed data link layer information is transmitted to a network layer. A new Internet protocol (IP) address for the new sub-network is acquired in the network layer using the changed data link layer information. The new IP address is transmitted to a transport layer and dynamic address setting is performed in the transport layer using the mSCTP.

A heating device having an improved heat resistance structure is provided. The heating device may include a heating element that generates heat, and an elastic conductive part that applies electricity to the heating element. A connector may be provided between the elastic conductive part and the heating element to preclude direct contact between the heating element and the elastic conductive part. The heating element may be fixed to one side of the connector, and the elastic conductive part may be fixed to the other side of the connector to allow current applied from the elastic conductive part to flow to the heating element.

A wireless communication system includes a plurality of nodes and a base station. The plurality of nodes include a connection node that is positioned at a BS range of the base station to transmit and receive a packet to and from the base station, or that is positioned outside a BS range of the base station to transmit and receive a packet to and from the base station through other connection nodes, and a relay request node that is positioned at a periphery of the connection node and that transmits a relay request to the connection node when the relay request node deviated from a BS range of the base station.
