Powerful light-weight portable computers, the availability of wireless networks, and the popularity of the Internet are driving the need for better networking support for mobile hosts. Current versions of the Internet Protocol (IP), make an implicit assumption that the point at which a computer attaches to a network is fixed and its IP address identifies the network to which it is attached. Packets are sent to a computer based on the location information contained in its IP address. Therefore, transparent host mobility is not supported by IP. But there is a growing need for users to be able to connect their portable computers to the Internet at any time, and stay connected even when they are on the move. Amongst various options available to implement host mobility, Mobile IP, which is an IETF (Internet Engineering Task Force) Draft Standard, is the most feasible one. The Mobile IP protocol, that is compatible with the TCP/IP protocol suite, allows a mobile host to move around the Internet without changing its identity. It is an internet (IP) layer solution to host mobility. Route Optimization, which is an extension to Mobile IP, allows a node to cache the location of a mobile host and to send packets directly to that mobile host. This thesis describes the development of a model to simulate Mobile IP with Route Optimization. An event-driven simulator was developed to study this protocol. Using this simulator, experiments were conducted to study the performance of the protocol under various changing network parameters. These experiments also establish the merits of Route Optimization over base Mobile IP.
