Answer :

Mobile IP is an open standard that allows users to keep the same IP address and stay connected  while roaming between IP networks. Mobile IP provides the facility to users to keep the same IP  address while traveling to a different network. This ensures that roaming of users could continue  communication without sessions or connections being terminated.
Components of a Mobile IP Network
Mobile IP has the following three components:
- Mobile Node
- Home Agent
- Foreign Agent
The Mobile Node is a device such as a cell phone or laptop. These devices have software that  enables network roaming capabilities.
The Home Agent is a router on the home network that maintains information about the device's  current location. It uses tunneling mechanism to forward packets from a device on the Internet  called a Correspondent Node.
The Foreign Agent is a router that works as the connection point for the Mobile Node when it  roams to a foreign network, delivering packets from the Home Agent to the Mobile Node.
