摘要： A method of allocating an address to a mobile node constituting a wireless network in a tree structure. A mobile node receives a wireless network identification (ID) and sets an address of the mobile node, based on the wireless network ID. Accordingly, an address is set based on a PAN ID which is a randomly set variable According to the method, addresses of mobile nodes can avoid conflict in a comparatively simple manner.

摘要： A local congestion-avoidance method in a wireless personal area network includes receiving data from a plurality of sensor nodes, generating a congestion-avoidance response signal with respect to the data first received, and broadcasting the congestion-avoidance response signal to the plurality of sensor nodes. The data may include, for example, a source address, a destination address, a sequence number, and a control frame. The control frame may include, for example, congestion-related information, a sequence number, a source address, and a destination address.

摘要： Disclosed is a method of assigning an address to a mobile node in a tree-structure wireless network, the method including sending a registration request to a management node by a mobile node when the mobile node joins with the wireless network, allocating a static address for the mobile node by the management node responding to the registration request, sending the allocated static address to the mobile node, and setting the static address received from the management node as its own static address by the mobile node. In accordance with the present invention, even if a mobile node moves and its dynamic address is changed, all nodes in the middle of the moved mobile node are not disconnected in communication.

摘要： A routing method is used to establish a data transfer path between a source node and a destination node in wireless networks having a tree structure. If a relay node relaying a data transfer receives data to be forwarded from a source node to a destination node, the routing table is searched to check whether the routing table stores information on a path to the destination node, and the received data is forwarded along a corresponding path if the path information to the destination node exists. However, if the information on a path to the destination node does not exist in the routing table, the routing table is searched to check whether the routing table stores information on a path to a parent node of the destination node, and; if the path information exists, the received data is forwarded along the path to the parent node.
