Based On The Ipv4 Mobile Ip System Ld-mip Design

As a solution to provide worldwide Internet mobility, Mobile IP is scalable, reliable and security. Actually, Mobile IP provides an IP routing mechanism, which makes possible a mobile node communicate with Internet during handover with a permanent IP address. It offers a handover procedure already, which is recognized to be sufficient in certain circumstances such as a laptop roaming in a wired network.In this thesis, we have a deep research in how to implement a Mobile IP system based IPv4. We putted forward the schemes of most necessary module in a Mobile IP system. During the design, we put forward some improvement of some questions in the system.
