See full text

A mobile node is arranged to perform a high-quality hand-over operation for eliminating an interruption time in communication and keeping the continuance of communication excellent. The mobile node has a function of interfacing with networks and includes a network quality monitor, a hand-over controller, and a network controller. The network quality monitor operates to monitor a network quality based on at least one of an intensity and a radio bandwidth of a radio wave received by network devices. The hand-over controller performs the hand-over operation of transmitting a care of address to an address registering destination in response to a state of the network quality before a communication is disconnected, changing a route of communication information, and switching a connecting destination into a new network. The network controller receives a response that indicates an update of the care of address in the address registering destination and keeping a function of receiving data from the network before being switched until the communication is disconnected.
