A method is provided for supporting mobility of a Mobile Node (MN) in a multi-hop Internet Protocol (IP) network, in which an MN that has moved from a source Personal Area Network (PAN) to a target PAN, sends a Router Solicitation (RS) message with an option for requesting its profile to a gateway of the target PAN, and receives a Router Advertisement (RA) message from the gateway in response to the RS message. The RA message includes a home prefix of the MN as the requested profile. The method supports mobility of MNs, enables unicast communication, and facilitates efficient use of the network.

A method is provided for registering a mobile router in an Internet Protocol version 6 over Low power Wireless Personal Area Network (6LoWPAN) network. The mobile router detects movement into a wireless network through the reception of a beacon message, and sends a Router Solicitation (RS) message requesting registration in the wireless network to a gateway. The gateway acquires an address of the mobile router from the RS message, stores the acquired address, assigns a new address to be used in the wireless network to the mobile router, and sends a Router Advertisement (RA) message with assigned address information and gateway address information, to the mobile router. The mobile router acquires the assigned address information and the gateway address information from the RA message.

Method for supporting route optimization in 6LoWPAN based MANEMO environment

Provided is a method for tracing-back an IP using marking information of a router stored on a hop-by-hop option header, which is one of IPv6 extension headers. According to the method, an attack made by an attacker is detected on the IPv6 network. If the attack is detected, information stored on a hop-by-hop option header of a packet received through the IPv6 network and marked by a router through which the packet has passed is extracted. After that, a reception path of the received packet is reconstructed and an IP of the attacker is back-traced using the extracted marking information.
