It ensures that the communication will continue without user’s sessions or connections being dropped. Terminologies: Mobile Node (MN): It is the hand-held communication device that the user caries e.g. Cell phone. Home Network: It is a network to which the mobile node originally belongs to as per its assigned IP address (home address). Home Agent (HA): It is a router in home network to which the mobile node was originally connected Home Addre
