碩士 === 國立交通大學 === 網路工程研究所 === 98 === A variety of wireless technologies have been popularized in recent years and enable users to connect to the Internet from almost everywhere. This brings the demand on the user mobility that allows a mobile device roams from one place to another without any application disruption. Proxy mobile IP (PMIP) provides network based mobility management to support unmodified mobile device but it cannot apply on non point-to-point networks suck as IEEE 802.11. On the other hand, the demand for IP addresses by mobile terminals can be solved by NAT which is unfortunately not compatible with MIP/PMIP. In this thesis, we propose a novel cross-layer network address translation scheme called Network Address Translation on Demand (NAToD) and integrate it with proxy mobile IPv4. The scheme allows PMIP running on the most popular IEEE 802.11 networks, and it only requires software upgrading on the AP itself. Doing this way, we can reduce the deployment cost as well as shorten the system deployment time. The experiment result shows that NAToD achieve better performance in most cases.
