Abstract: PURPOSE: A unit-directional link connection control method in a mobile temporary network and a recording medium storing program thereof are provided to accurately sense a uni-directional link by using transmission power loss on transmission path. CONSTITUTION: If an RA(Recipient Address) of a frame transmitted by each moving node is a BA(Broadcast Address) or an address of a corresponding moving node, a corresponding frame is received(S1). If the moving node does not receive a beacon message, it determines whether a relay request field has been set in a frame(S2,S4). The moving node checks whether a destination of a frame is included in a neighbor node list(S5). The moving node checks whether there is redundant power information to destination of the frame(S5,S6). If so, the moving node determines whether stored redundant power is greater than redundant power included in the corresponding frame(S7). If the stored redundant power is greater than the redundant power included in the frame, the moving node updates a TA(Transmitter Address) field of the frame and redundancy power information(S8). The moving node reflects the redundant power information when backoff time is generated before transmission of the corresponding frame(S9). The moving node transmits the frame to a moving node that can transmit the corresponding frame close to a destination of the frame(S10).

Abstract: PURPOSE: A dynamic address management device, a method therefor, and a wireless packet service method using the same are provided to make use of defined address resources efficiently by temporarily and dynamically assigning an Internet address in a certain point where a mobile host is currently located. In addition, the device and the methods are provided to perform a roaming function and enable a packet to be transmitted and received to/from an optimized path. CONSTITUTION: An address management request signal processing unit(202) receives an Internet address assignment request signal from an AAA(Authorization, Authentication, and Accounting) server. An address management unit(203) dynamically assigns an Internet address according to the address assignment request signal from the address management request signal processing unit(202). A name-address mapping management unit(204) maps a name of a mobile host with the Internet address dynamically assigned in the address management unit(203). An address management interface unit(201) interworks with an external address assignment and mapping function supporting server. A domain management unit(205) manages a domain of the mobile host. A data access request processing unit(206) processes a data access request signal for address assignment from the address management unit(203), the name-address mapping management unit(204), and the domain management unit(205). A mobile IP(Internet Protocol) database(207) provides dynamic assignment association information of the Internet address requested by the data access request processing unit(206).
