Mobile networking is becoming increasingly important as portable devices such as personal digital assistants (PDAs) and laptops become more powerful and less expensive, and as users need to be connected whenever and wherever they are. Mobile Internet protocol (IP) allows portable devices called mobile nodes to roam from one IP subnet to another while maintaining the communication sessions.
An IP address identifies a node (end point) as well as the subnet to which it is connected. The dual usage of IP addresses thus causes problems when a mobile node changes its point of attachment (indicated by a different subnet prefix) to the Internet. Packets destined to the mobile node would not be able to reach it while it is away from its home IP subnet because routing is based on the network prefix in a packet's destination IP address. To continue communication in spite of its mobility, ...
