This paper investigates application of active networking technology to enhance Internet Engineering TaskF orce (IETF) Mobile IP. We propose an active delivery scheme (ADS) that enhances the operation of Mobile IP. ADS contains the following functionalities: redirection of packets, fast handoff, efficient delivery of binding updates and a frameworkfor aggregation location update messages. Simulation results show significant improvements in transmission control protocol (TCP) performance with ADS. The performance of ADS is compared with those of original and optimised schemes. The improvements due to ADS are most significant when both communicating ends are mobile and during high handoff latencies.
