Performance of the Double Tunneling with Handoff Prediction in Mobile IP Network
Abstract: Mobile IP protocols allow a mobile host to send and receive
packets addressed with its home IP address, regardless of the IP address of
its current point of attachment in the Internet. Four routing schemes, home,
optimal, hierachical and point forwarding approaches are discussed with regard
to the handoffs. In the existing methods packets are delayed and lost during
the change of the care-of-address from an old foreign agent to a new agent.
To
handle the packet loss and delay problem we propose a double tunneling method
in which received packets at an agent are copied and sent to both the old and
new foregn agents. The method is backed up by the predicted handoffs. Computational
results show that the double tunneling method outperforms existing handoff procedure
in view of lost and delayed packets.
