|dc.description.abstract||As wireless technology has improved, the demand for constant internet connectivity
increased. With the invention of Mobile IP, users are still more interested to have connection to
the internet while moving from one network to another. During the mobility, the mobile host
moves from one network to another, undergoes the handoff process, and registers with the new
network. Due to the scarcity of IPv4 addresses and other limitations, new Internet Protocol
version 6 (IPv6) has evolved. In the real world, planning is being done to deploy IPv6 along with
the IPv4 network. The IPv6 node should understand IPv4 addressing and its features while
communicating with it. When considering mobility in both IPv4 and IPv6 networks together, it is
a bit complicated where either the mobile host or any other entity in the network should
understand both IPv4 and IPv6 networks.
In this thesis, research was centralized in the scenario where both internet protocol
versions IPv4 and IPv6 are active and mobility is introduced between them. The research deals
with the handoff process and registration of the mobile node with the agent in the new network.
The author proposed a new handoff algorithm with the basic security involved in the process
which can be used as model before planning to introduce mobility between IPv4 and IPv6
protocols. The significance of the algorithm is to reduce the handoff latency by enhancing the
functionality of the Tunnel End Point (TEP); this in turn reduces the tunneling of the data twice.
The research, analysis is done on the complete handoff process by varying different
parameters involved in the process. An analytical model is proposed to support the algorithm.
The effects of the parameters are studied. The results of the proposed analytical model were
studied in comparison with the traditional schemes.||en_US
