Transparent mobile IP: an approach and implementation

The problem of Internet terminal mobility without reconfigurations and host software modifications (transparent) is presented. A solution based on the introduction of network agents, with proxy ARP and IP tunneling features, has been introduced discussed and implemented. Some strategies for routing optimization, in order to avoid triangular paths, are investigated and tested Implementation results demonstrate the value of this approach in terms of both functionality and performance and are of interest in indicating a simple way of supporting the increasing request for mobility.
