Background
Handover algorithm between different domains
After host signal degrade, and mobile can not contact current attachment point, the mobile node then flood signal try to contact any available attachment points.
Attachment point itself would know the mobile host in the edge of its domain if attachment point keeps a domain verge range information table (e.g., GIS system of Cellular). Attachment point tell the mobile host it maybe among the verge range, the mobile host should begin to find its available attachment points.

Proposal
To propose a method for mobile host to know it is moving to a different domain.
802.11, , Cellular and so on…
To propose a predictive handover before detaching current domain for seamless connectivity among different domains.

Open Issues
Needs an administrator’s network design
DID should be assigned on the edge system of each domains.
Ambiguous verge area among them.
Particularly, overlapped domain.
WLAN inside Cellular.
Expanded message for including DID.
Cellular
WLAN

Conclusion
Predictive handover is a essential element to seamless connectivity among different domains.
WIEN is a good place to discuss this issue.
