Delegated IP: A Mobile IPv6-Based Protocol to Support Session Delegation

This work defines a new protocol, Delegated IP, that uses Mobile IPv6 to allow session migration from a mobile node to a target node without affecting the other session endpoint at the correspondent node. Moreover, the concept of session delegation is introduced to indicate that a master device, the mobile node, delegates a session to a target device, or target node, to which the session is migrated while the first one can still manage the target device. The proposed session delegation procedure requires state handover from the mobile node to the target node and the interaction between the application, which triggers the procedure, and the network layer. At the target node, Delegated IP mangles packets belonging to the delegated session at Mobile IPv6 layer so that the mobile node home address is used instead of the target node's home address which appears as care-of address. Whereas this protocol requires application awareness in the mobile node and the target node, it is totally transparent for a Mobile IPv6 correspondent node and a Home Agent, allowing a vendor's implementing its own solution without compromising interaction with the ecosystem.
