Enhancing Survivability of Mobile Internet Access Using Mobile IP with Location Registers

The Mobile IP (MIP) protocol for IP version 4 provides continuous Internet connectivity to mobile hosts. However, currently it has some drawbacks in the areas of survivability, performance, interoperability with protocols for providing QoS. We have proposed an alternative protocol, Mobile IP with Location Registers (MIP-LR), which overcomes some of these drawbacks and is closer to the "service node" database approach used in the Public Switched Telephone Network (PSTN): before launching a packet to the mobile host, the sender first queries a database, called the Home Location Register (HLR), to obtain the recipient's current location. MIP-LR is designed for operation in enterprise environments or within logical administrative domains. In this paper we focus on showing how MIP-LR enhances the survivability of MIP by eliminating some of the functions which MIP introduces for mobility support, allowing the HLR to be placed outside the mobile's home network in case the ...
