The current use of IP address in network application session identification cannot preserve the session when the IP address changes. Host Identity Protocol (HIP), which is an identity-location separation protocol, provides a better framework to build solutions for mobility, multi-homing, and security by adding a host identity layer on top of the IP layer. Yet modifying the IP protocol stack and adding mobility as well as other solutions to all the hosts can be impractical to deploy and interoperate with existing IP hosts. This paper proposes a network-based HIP service as well as mobility solution at HIP layer to all mobile hosts.
