Mobile computing in the true sence will be provide an environment where a user will be able to continuously access data and services in state of mobility.Mobile computing should not be confused with portable computing.In a portable computing environment,we move with the computing device from one location to another and use the network wile stationary.For example, while I'm in office with my laptop computer, I use the company Ethernet LAN; and,when I am back home, I use the broadband at home.
A data connection between two end-points TCP/IP network requires a source IP address,source TCP port and a target IP address with a target TCP port. The question is how do we allow mobility while a data connection is alive.The technology to do so is "Mobile IP".The term "mobile" in "Mobile IP" signifies that, while a user is connected to applications across the Internet and the user's point of attachment changes dynamically, all connections are maintained despite the change in underlying network properties including the point of attachments.
