Abstract: PURPOSE: An apparatus for a TCP congestion control, a method thereof and a recorded medium recorded with a program executing the same are provided to perform congestion control in consideration of rearrangement of a packet. CONSTITUTION: If the number of received duplicate response of a transceiver(201) is over a duplicate response threshold value, a controller(204) performs a first congestion. If the transceiver receives an acknowledgement response to the first congestion control before the expiration of the verification timer(202), the controller verifies the generation of packet rearrangement. The controller performs a first resetting of more than one of duplicate response threshold value, a slow start threshold value, a congestion window.

Abstract: PURPOSE: An apparatus and a method for routing based on a proxy mobile ipv6 network and a mobile ad hoc network are provided to store and manage first and second identification numbers for a mobile node in the binding update list of a mobile access gateway. CONSTITUTION: An MAG(Mobile Access Gateway)(31) judges whether or not a second identification number exists in a pre-stored binding update list. If the second identification number exists, the MAG performs a comparison operation whether or not the first identification number is identical to the second identification number. The MAG judges whether or not a mobile node executing an Internet gateway is changed. If so, the MAG modifies not only the first identification number of the change mobile node related to the second identification number, but also a link local address.

Abstract: A method and a system for distributing a key using an N dimension lattice of a sensor network are provided to reduce overhead for calculating a shared key and a pass key by distributing shared keys corresponding to a position on each axis in a sensor node. A distributing server performs one-to-one correspondence about positions inside an N dimension lattice and all sensor nodes, and performs one-to-one correspondence about positions on each axis of the N dimension lattice and a plurality of shared keys. The distributing server distributes the shared keys corresponding to the positions on each axis of a position inside the lattice of each sensor node(S10). The sensor node finds a shared key having a position on the same axis as the other sensor node, generates a symmetric key by the shared key, and transmits data to the other sensor node(S20). The sensor node transmits a pass key to the other sensor node via a direct middle node having a position on the same axis about the sensor node and the other sensor node(S30). The other sensor node decodes the data encrypted by the pass key and the symmetric key(S50).

Abstract: A clustering routing method for energy and distance of a wireless sensor network and a device thereof are provided to make a size of a cluster small by increasing selection probability of a cluster head according to a distance to a data collecting device, thereby realizing uniform energy consumption of the cluster head. Each sensor node determines whether it is selected as a cluster head by probability having a bigger value as it is farther from a collecting device(S11). A sensor node which is not selected as a cluster head selects one among the selected cluster heads(S12). The sensor node transmits sensing information by the selected cluster head and the cluster head merges the sensing information and transmits it to a data collection device(S13).
