Link Layer Assisted IP Mobility Protoco

Abstract

As the popularity of IEEE 802.11 rises, many problems have been arisen that were absent in the traditional wired networks. A serious problem has arrived from the movement of mobile nodes - this mobility characteristic will make the data transmission mechanisms differ from before. A general solution to this problem is Mobile IP. ButMobile IP in itself has problems and will create a big latency. The roaming nodes will need to complete all registrations before being able to receive data. The registrations then become the bottleneck in data transmission. In this paper, it is proposed that a novel link layer handoff is designed to deliver that data to a destination before the roaming nodes complete its Mobile IP registrations. The proposed method is completely independent of network layer; therefore, no matter Mobile IPv4 or Mobile IPv6 is used, the proposed method can work correctly. No modification to the existing specification is necessary in Mobile IP.
