Abstract: The existing mobile IP handoff scheme has some problems such as more handoff latency, easy to lose packets and poor security. From the point of the motion detection, the key problem of mobile IP handoff, this paper presents and implements an efficient mobile IP handoff scheme which can initiatively predict neighbor mobile IP. It adopts the adaptive initiative predictive algorithm, can predict intelligently according to the network conditions and the movement of the mobile host, and thus a fast and smooth handoff is achieved. Simulation results show that it could effectively solve the above problems, reduce greatly the handoff latency and the counters of handoff, guarantee the packet’s arriving in time, increase the handoff performance of the system, and maintain a better QoS.

Key words: Mobile IP, Adaptive initiative prediction, Handoff scheme, Hierarchical mobility management
