IMPLEMENTATION OF MOBILE IP HOME AGENT AND FOREIGN AGENT ON WINDOWS NT 4.0 WORKSTATION PLATFORM

Abstract

Mobile IP is an enhancement to the existing Internet Protocol (IP) which allows a mobile computer to roam freely on the Internet while still maintaining the same IP address and without losing existing connection. The Mobile IP architecture defines special entities called the Home Agent and Foreign Agent that cooperate to allow a Mobile Host to move without changing its IP address. This dissertation presents to the reader the implementation of Mobile IP Home Agent and Foreign Agent on the Windows NT 4.0 Workstation operating system. The design implemented for the Home Agent and Foreign Agent is made up of a combination of source codes in both the user and kernel modes of the Windows NT 4.0 Workstation operating system. For its kernel implementation, the author has utilized the NDIS Intermediate Driver, which is layered beneath the native Microsoft IP stack.
