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 bidirectional tunnelling solution proposed within the IETF's NEMO (Network Mobility) working group.
