Mobility as an integrated service through the use of naming

As Mobile IP is deployed, so the requirements for its deployment evolve, reflecting the actual use of IP networks today. This includes the ability to use Mobile IP with IPsec, NATs and multi-homed networks. Furthermore, new requirements arise as people start to use IP in scenarios where the whole network is mobile (e.g. military networks), and where edge-networks may not be IP-enabled (e.g. sensor networks), but there is a requirement to interoperate across an IP network. In all these cases, rather than engineering retro-fits, creating an increasingly complex network landscape with possible unforeseen feature interactions and dependencies, we would prefer an integrated architectural solution. We present, from our ongoing work, a solution that would seem to meet all these needs, through a modified use of naming and addressing. Our proposal is incrementally deployable and existing core network routers & routing protocols need not change.
