A wireless networking device and a communication method using the same. The wireless networking device includes an address generator to generate an address to be used in a predetermined wireless network, a router information setter to set router information of the wireless network, and a controller to control operation of the address generator and the router information setter according to the router information and perform hand-off to a wireless network that corresponds to the router information.

Wireless networking device and communication method using the same

Provided is an apparatus and method for transmitting packets in a wireless network. The apparatus includes a motion calculation unit, a transmission repetition adjustment unit, and a packet transmission repetition unit. The motion calculation unit calculates the motion value of a mobile terminal. The transmission repetition adjustment unit receives N-value determination information and determines the number of repetitions (N value) of transmission of a packet transmitted and received by the mobile terminal based on the received N-value determination information, and the motion value calculated by the motion calculation unit. The packet transmission repetition unit repeatedly transmits the packet, which is received from a data link layer, to a physical layer according to the N value determined by the transmission repetition adjustment unit.

Apparatus and method for transmitting packets in wireless network

The present invention relates to a domain name service system and method thereof. According to the present invention, a domain name service can be provided through a mobile host and domain name servers having smallest hop counts, based on position information on the domain name servers included in external links. Therefore, a domain name service can be provided within a short time regardless of operating modes of the domain name servers. Furthermore, it is possible to reduce system traffic since the addresses of optimal domain name servers are provided to edge routers.

Domain name service system and method thereof

A network apparatus for a stable handoff in an IP-based mobile ad hoc network system and a handoff method using the same. Present invention enables a handoff to be stably performed by pre-configuring a handoff to a new access router. The network apparatus of the present invention comprises a movement-determining unit for determining movement depending on the signal strength upon reception of a packet among network apparatuses operating on a communication mobile ad hoc network, and deciding a handoff to a new access router; a router-configuring unit for configuring information on the new access router for the handoff by performing beforehand the handoff to the new access router according to the results of the determination in the movement-determining unit; and a handoff-processing unit for performing the handoff to the new access router using the pre-configured information according to the determination in the movement-determining unit.
