Abstract: PURPOSE: A data packet transmission method is provided to improve the stability of transmission by preventing the degradation of total bandwidths. CONSTITUTION: An access point receives a unicast packet transmitted from a predetermined terminal connected to a wireless network (S401). The access point determines a data packet transmission method including rapid transmission speed between the broadcast method or the unicast method based on the number of terminals connected to a wireless network and the access point (S402). The access point transmits broadcast packet converted into the unicast packet to the access point and each terminal connected to the wireless network when the transmission speed of the broadcast method is faster than the unicast method (S403-S404). [Reference numerals] (AA) Start; (BB) Finish; (S501) Receives packets; (S502) Convert into external network address; (S503) Transmit to external interface; (S504) Broadcasting transmission is faster.; (S505) Convert into each connected terminal unicast address; (S506) Transmits to access point interface; (S507) Convert into an original broadcast address

Abstract: PURPOSE: An energy cognitive routing method considering mobility in a sensor network and a device thereof are provided to set a route in consideration of a remaining energy amount of a sensor node, thereby lengthening lifetime of a wireless sensor network. CONSTITUTION: A mobile node transmits a help message to adjacent nodes in consideration of an available remaining energy amount(S120). The mobile node checks a response for the help message(S122). When the mobile node does not receive a route setup message from the adjacent nodes, the mobile node notifies data transmission unavailability to a previous sensor node(S130). When a sensor node requesting data transmission to the mobile node is not a source node, the sensor node deletes route information for information for the mobile node(S132,S134).

Abstract: PURPOSE: A packet transmitting device in a wireless network and a method thereof are provided to reduce the frequency of using real time data packets which are not transmitted within a fixed period of time. CONSTITUTION: A delay time calculating unit(100) calculates predicted delay time to a destination based on a hop number and channel access time for transmitting a received packet to the destination. A packet processing unit(110) discards the received packet or inserts the received packet to a transmission queue by comparing the predicted delay time with a preset allowable value.

Abstract: PURPOSE: An inactivity / activity duty cycle method is provided to maximize the efficiency of a channel recycle by minimizing the size of a virtual cluster. CONSTITUTION: Each node dynamically searches a 1-hop distance neighbor node by a three step handshake of a Beacon/Approval/ACK frame on a free contention access period of a time frame. Each node selects an initial activation schedule. The activated node selects the next active schedule by the second handshake of the Beacon/Approval frame on the control period. The node activated on the corresponding time slot as an owner has an exclusive channel access right for the corresponding time slot. The node transmits data on the transmission time.
