Mobile computers require Mobile IP to preserve connectivity and properly route information while roaming over foreign networks. Registration, forwarding delay, and tunnel initialization diminishes the performance of mobility protocols during handoff. We propose a proactive rather than reactive solution to improve the performance of Mobile IP. We extend the current protocol with two new entities: ghost Mobile Host and ghost Foreign Agent. Our target is mobility scenarios in which mobile hosts are moving at a very high-speed. Our protocol extension uses the Kalman filter to determine the trajectory and speed of the mobile host and to proactively allocate resources for Mobile IP. Preliminary experiments conducted using the RAMON emulator show that the proposed predictive methods offer a promising range of 20-50% of performance improvement. © 2004 IEEE.
