Reducing the Impact of Mobile IP Handoff by the Recorded Neighbor Information

Abstract

The routing protocol Mobile IP is introduced in 1996 to facilitate wireless networking and mobile communication. The problem encounters Mobile IP is: When a mobile node (MN) hands off between different agents, packets may get lost or the node itself may get disconnected. A number of handoff schemes have been proposed to improve the situation but can reduce only the impact of Mobile IP handoff in ideal topologies with enough signal overlapped areas. The goal of this investigation is to reduce the handoff latency to attain seamless communication even under tough topologies. By adding a recording feature to every agent to preserve the information of neighbor agents, our new scheme can help a migrating MN keep receiving packets during the handoff period to attain the desired seamless connection even in the toughest topologies.
