Abstract: A system for communication between a mobile node and a communications network is provided for use with a communications network having one or more communications network nodes that define a foreign agents and that communicate with the mobile node in a predefined region. The system includes a ghost-foreign agent that advertises a foreign agent so that the mobile node is aware of the foreign agent when the mobile node is located outside the predefined region. The system further includes a ghost-mobile node that signals the foreign agent in response to the foreign agent advertising and based upon a predicted future state of the mobile node.

Abstract: A system for emulating mobile network communications can include one or more wireless nodes configured to variably adjust signal reception sensitivity and signal transmission strength; at least one mobile node configured to wirelessly communicate with selected ones of the wireless nodes; and a network emulator communicatively linked to each wireless node. The network emulator can replicate attributes of a wired communications network. The system also can include a controller communicatively linked with the wireless nodes and configured to control signal reception sensitivity and signal transmission strength of each said wireless node, as well as a home agent configured to interact with at least one mobile node via selected ones of the wireless nodes.
