In general, the nested mobile networks easily suffer from a bi-directional pinball routing with hierarchically multiple mobile routers. To handle this matter, several route optimization schemes have been proposed. But, to make network mobility feasible in public wireless Internet, well-defined authentication, authorization, and accounting protocols (AAA) should be accompanied. Hence, we combine a route optimization scheme with AAA architecture in network mobility in this paper. And we propose a new accounting system to support the combined architecture appropriately. We evaluate various existing route optimization schemes with AAA in terms of delay.
