An efficient connection scheme for mobile IP

Computer users in this varied and rapidly changing world does not stay in one place, and the correspondence among computers through the Internet has increased due to the quick development of Web based applications. But the Internet TCP/IP communication protocol was not designed to cover a mobile host, so the IP protocol should detect a mobile host that independently moves and have a moving management system to transmit the data. That is, the mobile IP protocol, must provide the mobile host with the continuous connection to the Internet. The mobile IP proposed by the IETF is efficient, but if the mobile host moves frequently and communicates with others in a specific zone, it may be inefficient. This is because there would be a delay in registering the mobile hosts and in setting up a secure tunnel in the Internet environment, and also in transmitting the data. These inefficiencies were maximized by the mobile host that has an incessant mobility. When the mobile host registered itself with the home agent, the registration cost can be reduced by using boarder router to manage the mobility within a specific zone. It enables the mobile host to detect quickly by placing an anchor FA that uses the anchor chain scheme, which is a combined pointer forwarding and caching method. Therefore, to solve the inefficiencies of the mobile IP, we suggest the border router and anchor FA to manage the mobility in the specific zone and to efficiently detect the mobile host.
