The technical approach used can perform data conversion of heterogeneous databases located on different nodes of the network, such as Oracle, Sybase, Informix, MS SQL Server, SQL Anywhere and Foxpro. The conversion system adopts the Client/Server architecture and provides visual integrated interface for users.展开更多

The proposed AIP with the RSA-based proxy signature reduces handover delay time and communication message overhead when the mobile node moves between the heterogeneous networks. It defines new AlP Type Length Value （AlP TLV） in MIH frame format and uses the MIH Information Server （MIHIS） for issuing signature. The MIHIS can generate a signature on behalf of the AAA server and then the signature can he used by mobile node for a pre-authentication. For low handover delay, the proposed AIP performs pre-authentication processes with MIP protocol before layer 2 handover. Also, this paper analyses the performance of the handover and compares with the non-secure MIH.展开更多
