Abstract-- Mobile IP and SIGMA are handoff schemes at
the network layer and the transport layer respectively. SIGMA
is based on IP diversity and aims to improve the handoff
performance over Mobile IP by reducing the handoff latency.
We compared the performance of the handoff schemes in an
experimental test bed. Results show that SIGMA has a lower
handoff latency when compared to Mobile IP. Moreover, SIGMA
can achieve a seamless handoff between two subnets.
The last two decades have seen considerable growth in
wireless networks which allow users to access the Internet
access without being tied down to one location. The current
