Abstract:
Mobile IPv6 is a network layer protocol. It allows a Mobile Node to remain reachable by
a Correspondent Node while roaming from one network to another network. The
movement of a Mobile Node away from its home link is transparent to the higher layer
protocols as well as to the applications. In Mobile IPv6, a Mobile Node directly updates
its current location information to a Correspondent Node using a route optimization
method. Route optimization helps to culminate the packet delay incurred due to
suboptimal route traversed by the packets from a Correspondent Node to a Mobile Node
in Mobile IPv4. However, it introduces packet losses during Mobile Node's transition
from one foreign network to another foreign network. This packet loss increases as the
mobility of the node increases. In this thesis, we propose a probabilistic scheme to reduce
this packet loss. Our solution is based on the Mobile Node's mobility prediction at the
Correspondent Node and a buffering mechanism at the Home Agent. Simulation results
prove the effectiveness of our scheme in case of reducing the packet loss problem
besetting the Mobile IPv6.
