  • IPV6 address management method and gateway performing the same
    Patent number: 9173129
    Abstract: A management method for an IPv6 address for use in a gateway is provided. The method includes receiving a packet including an IPv6 address, extracting a MAC address from the IPv6 address of the packet, generating a compressed address by inserting a previously defined bit sequence into the MAC address, and storing the compressed address and the IPv6 address in a mapping table. The packet is received from a WPAN (Wireless Personal Area Network) node.

  • Network system
    Patent number: 9148373
    Abstract: A method for packet processing in a network including a plurality of terminals, includes generating, by a first terminal, a packet including a geographical address. The first terminal transmits the packet transmitted to a destination. The geographical address includes a location information field having location information of the first terminal and a range field indicating whether the destination is a single destination representing that the destination is a target terminal or an area destination representing the destination is a target area. The range field has range information of the target area in the case that the destination is the area destination.

  • DYNAMIC ROUTING METHOD IN AD-HOC NETWORK AND NETWORK DEVICE THEREFOR
    Publication number: 20150043364
    Abstract: A dynamic routing method of a network device in an ad-hoc network is provided. The method includes (a) collecting a factor comprising at least one of the number of neighboring network devices, a moving speed and an amount of data traffic; (b) setting a routing information transmission mode based on a value of the collected factor; and (c) processing at least one of transmission and non-transmission of routing information according to the set routing information transmission mode, wherein in the step (b), when setting the routing information transmission mode, if the value of the factor is less than a preset threshold value, the routing information transmission mode is set to an active mode, and if the value of the factor exceeds the threshold, the routing information transmission mode is set to an inactive mode.
