Abstract

In order to improve the routing efficiency and reduce handoff latency, we have proposed an enhancement of Mobile IP (MIP) called MIP with Home Agent Handover (HH-MIP) to enjoy most of the advantages of Route Optimization MIP (ROMIP) but with only a small increase of signaling overhead. In HH-MIP, the concept of Temporary Home Agent (THA) was proposed and the mobile host (MH) registers the new CoA with its THA rather than its original HA. In this paper, we propose a multicast extension for HHMIP (HH-MIP/ME). HH-MIP/ME reduces routing inefficiency in bi-directional tunneling without generating large signaling overhead. Simulation results demonstrate that the proposed scheme enjoys small handoff latency as well as routing efficiency and the number of control packets generated in proposed scheme is significantly less than that in other approaches.
