Mobility support in IPv6 networks (MIPv6) has been ready for release as
an RFC. However, there were some stimulating major discussions on necessary
improvements needed for real-time communication requirements. One example of
such requirements is the continuing work on the “Fast Handovers For Mobile IPv6”
protocol that aims to reduce the packet loss and latency inherent to the handover
process. The handover process is the time spent when the mobile node is changing
from one access router to another. During the handover period the mobile node is
unable to send or receive data and the connection could be interrupted. Therefore,
packets could be lost or delayed due to intermediate buffers. Fast Handover Mobile
IPv6 (FMIPv6) is then proposed to alleviate the packet loss during handover period.
In this research, the study presents a set of experiments with an
implementation of that protocol and performance evaluation. All tests were done over
IEEE 802.11g Wireless LANs, and were performed by using the MIPv6, UMIP and
FMIPv6 protocol implementation for the Linux operating system. The study considers
the performance of TCP/UDP throughput, UDP packet loss and handover latency.
