Mobile IPv6 without home agent

In Mobile IPv6, the home agent (HA) is an essential component.Mobile nodes will not function properly if the HA cannot be reached.Enhanced Route Optimization uses a Cryptographically Generated Home Address in Mobile IPv6, to enhance the security and reduce the handoff delays.Unfortunately, a CGA cannot provide home prefix validation.The 'home test ' signal remains needed for handover purposes.When the correspondent node or the mobile node cannot connect to the home agent for any reason, a "return-to-home" flooding attack could occur if this requirement were ignored.This thesis proposes a solution to enhance the mechanism for Mobile IPv6 communications and avoid this problem, and thus allow Mobile IPv6 to continue operating when no home agent is available.
