Hi Aimin,
BTW, about signaling overhead, I think we can adopt the concept of Hierarchal Mobile IP by choosing some RSs acting like Gateway Foreign Agent(GFA) to handle locatized handover signals.

Do you mean a centralized controlled system architechture? If the number of hops is more than two, there will be a lot of signaling needed to collect necessary information for routing or handover, etc. Because there are always a lot of MS moving simultaneously from one RS-cell to the other RS-cell, so the signaling overhead might become very huge and a lot of bandwidth will be used .
I think it better to have a combined architechture. The last 2 hops can be centralized controllized by a high capability RS, however, the first few hops from MMR-BS to this RS should be distributed controlled.
In the combined architechture, an MS can be connected to any RS with different capability. However, the intermediate-RS should have better to be high capability to support distributed controlled.
Best regards,
Aimin

Hi Saravanan,
Thanks for your supporting. Actually, I also think the term of "routing" is not appropriate to be adopted in any 802.16j documents, because it is no need to have routing protocol in RS.
What do you think?
