....to another while maintaining continuous network connections. The location of a mobile node is therefore independent of its identity. A challenge is to manage location information in such a way that provides seamless network access for mobile nodes while retaining compatibility with wired networks. [4, 6] Researchers have investigated IP based protocol for mobile internetworking, leading to the development of a proposed standard for IP mobility support called Mobile IP [3, 1] In Mobile IP, each mobile node is assigned a long term IP address on a home network called a home address. While away ....

....foreign agent relays the registration reply to the mobile node. Registration requests and replies are sent as UDP packets to port 434. They must be authenticated with the Mobile Home Authentication Extension. The default algorithm is keyed MD5 used in pre x sux mode with a key size of 128 bits [8, 4]. Besides a home address and a network mask, a mobile node must be con gured with a mobility security association for each home agent. Figure 6: IP Datagram Routing in Mobile IP The above gure indicates the triangle routing when a correspondent node S sends IP datagrams to a mobile node M ....

....node at the home agent changes whenever it moves from one IP subnet to another. This could lead to frequent registrations with the home agent, which can incur a long handoff delay when the mobile node is far away from home. This can cause significant packet drop and throughput reduction [5] In [3], Mobile IP is extended with a dynamic routing agent between the home agent and the foreign agent of a mobile node. The routing agent serves as the current Supported in part by the National Science Foundation Grant NCR 9628126 and by the Texas Higher Education Coordinating Board, Advanced ....

....the routing agent to the home agent. The analysis shows that both handoff delay and the extra tunneling cost per IP packet can be controlled and bounded. The rest of this paper is organized as follows. Section 2 reviews the basic framework of Mobile IP [6] and the extension with routing agents [3]. Section 3 presents a performance analysis of Mobile IP and the extension with routing agents. We conclude with a brief discussion of related work and some issues for future work. 2 Mobile IP and the Extension with Routing Agents This section reviews the registration and mobility management in ....

....when a mobile node does cross regions at the top level of the hierarchy, registrations still involve home agents that may be far away, causing a long handoff delay. The fast handoff scheme in [5] handles only intra subnet movement, which is orthogonal to the handling of inter subnet movement. In [6], Mobile IP is extended with a dynamic routing agent between the home agent and the current foreign agent of a mobile node to exploit locality of movement between IP subnets. The routing agent serves as the current location of a mobile node to the home agent. A distinctive feature is that ....

....node in the hierarchy. Registration requests are sent to the foreign agent at the lowest level in the hierarchy that remains the same across a handoff. IP datagrams for a mobile node are sent to the home agent and then tunneled down through the hierarchy of foreign agents to the mobile node. In [5], we have introduced a dynamic routing agent between the home agent and the current foreign agent of a mobile node. For macro mobility, the routing agent serves as the current location for a mobile node at the home agent. The change of the routing agent requires registration with the home agent ....

....wired network is loaded. Overall, routing agents make it possible for a mobile node to control its location dynamically according to various cost criteria.

Section 3 presents performance analysis of Mobile IP and routing agents based upon registration cost, packet drop and packet tunneling.
