Mobile IPv6 and AAA architecture based on WLAN

Mobility support for Internet devices is quite important for consumer electronics and the number of the handled device is growing up quickly. However, the IP addresses are not enough for the number of the rapidly grow devices in the All-IP generation. So the IPv6 is adopted to solve these problems. Our purposed structure is based on the IEEE 802.11. However the 802.11 has denounced drawback in its security issues. Further, for various Internet service providers´ points of view, the accounting is even a more imminent problem. So a mechanism combining mobile IPv6 and AAA based on IEEE 802.11 to overcome these problems is essential. We use AAA mechanism to protect the security, let the architecture have the functionality of authentication, authorization, and accounting. We will discuss the benefit of AAA with the others and the reason why we choose AAA to combine the mobility architecture.
