A novel enhanced authentication scheme supporting forwarding mode in heterogeneous hierarchical mobile IPv6 networks

This paper makes its focus on how to reduce the longer delay and extra cost arising from the combination of authentication, authority and accounting (AAA) and hierarchical mobile Internet protocol version 6 (IPv6) further. Firstly, a novel enhanced authentication scheme (E-AAA) is proposed, which supports fast handover mode and forwarding mode between different mobility anchor points (MAPs). Secondly, a cost analysis model is established based on E-AAA. From the theoretical analysis, it could be noted that the cost is affected by average arrival rate and residence time. Finally, the performance comparison demonstrates that the total cost of using E-AAA is much lower than that of the traditional solution, the longer the distance between Root AAA Server (RAAAS) and its home domain is, the more obvious the efficiency shows.
