Abstract-- Mobile IP, an industry standard for handling mo-
bility, suffers from high handover latency and packet loss,
in addition to change in network infrastructure. To overcome
these problems, we proposed a novel approach called Seamless
IP diversity based Generalized Mobility Architecture (SIGMA).
Although SIGMA achieved a low latency handoff, use of IP
diversity resulted in some instability during handoff. In this
paper, we propose a new handoff policy, called HANSIG-HR, to
solve the instability problem of SIGMA. HANSIG-HR is based on
