Efficient Alternatives to Bi-directional Tunnelling for Moving Networks

The following paper discusses ways to provide reachability to devices residing within a moving network. A device is reachable when an external node can successfully contact it. In this paper we introduce two novel solutions to support reachability in moving networks – one based on a proxy signalling agent and the other on the use of temporary names. We analyse aspects of these proposals compared to existing solutions, namely the bi-directional tunnelling solution proposed within the IETF’s NEMO (Network Mobility) working group.
