Abstract: PURPOSE: A network management method and a device thereof are provided to support a restoration for a connection using a link by rapidly connecting the link to a neighbor mesh node. CONSTITUTION: When an entry node entering into a transmission range is sensed, a neighbor node management unit(1100) selects the entry node and a mesh node as an agent node including a neighbor node from a plurality of neighbor nodes. The neighbor node management unit forms a link with the entry node through the agent node. A transmission and reception unit(1300) receives a message from the plurality of the neighbor nodes. The transmission and reception unit transmits the received message to the neighbor node management unit.

Abstract: PURPOSE: A routing method for supporting QoS(Quality of Service) in a wireless network and apparatus thereof are provided to allocate resources by establishing a connection for each intermediate node in the wireless network. CONSTITUTION: A connection management unit determines a next node and a predicted path in order to contact to a destination node(S600). The connection management unit deducts the QoS of a link(S610). The connection management unit requests resource allocation to a resource allocation unit in order to satisfy with the QoS of the link(S620). When the allocated resource is satisfied with the QoS of the link, the connection management unit transmits a connection establishment request to the connection management unit of the next node(S630,S640). The connection management unit stores connection information(S650).

Abstract: PURPOSE: An adaptive interfere avoiding apparatus and method in a channel hopping-based wireless ad-hoc network are provided to classify an unavailable channel on the basis of the measurement of node channel quality. CONSTITUTION: A channel quality measurement unit(110) measures channel quality with a received frame. A channel information storage unit(120) stores the measured channel quality information. Based on the channel quality information, an unavailable channel classification unit(130) classifies an unavailable channel through which communication is not performed later. An unavailable channel propagation unit(140) transfers a unavailable channel list to a neighbor node. A transceiver(150) transmits and receives a frame through a channel which is not classified as the unavailable channel.
