Abstract--SIGMA is an IP diversity-based mobility manage-
ment scheme that aims to reduce handoff latency and packet loss
of Mobile IP. In this paper, we propose a power-aware version
of SIGMA (called PEARS) which reduces power consumption by
intelligently switching off network devices, and improves handoff
performance by reducing the number of unnecessary handoffs.
The effectiveness of PEARS and SIGMA have been evaluated
on a Linux-based experimental testbed. PEARS has been found
to require considerably less power than SIGMA. The schemes
used in PEARS can also be used to reduce power consumption
of multihomed mobile nodes and routers.
The last two decades have seen considerable growth in
wireless networks which allow users to access the Internet
