Abstract

The IETF Mobile IPv6 protocol has been developped to manage global (macro) mobility. It is not adapted to local (micro) mobility since it does not support any kind of hierarchy. This paper presents a hierarchical protocol, built on top of Mobile IPv6, that separates local mobility (within a site) from global mobility (across sites) management. Local handoffs are managed locally and transparently to a mobile node' correspondent hosts while global mobility is managed with Mobile IPv6. Our scheme is flexible (several levels of hierarchy can be used), scalable, interworks with Mobile IPv6 and can be deployed gradually.
