Network Security 2
Answer – 1:
According to Darwich, a mobile IPv4, and mobile IPv6 are having different benefits for
datagram transfer, but latency of network is high in case of MIPv4. There are some basic terms
in the mobile network, which are Mobile Node (MN), Home Agent (HA), Foreign Agent (FA),
Access Router (AR), Care-of Address (CoA), Home Address (HoA), and Return Routability
(RR). Basic architecture of mobile network is shown in below figure with all the elements.
Source:[ CITATION Dar11 \l 1033 ]
Home Agent, Foreign Agent, and Mobile node are three main parts for handle mobility.
In a mobile network, a static home address is used for the connection making with the upper
layer of network, such as TCP, and care-of address is used for routing purposes[ CITATION Cha12 \
l 1033 ].
A binding process between HoA and CoA, which is called home-agent registration. It
will happen, when a MN is move from one FA to another FA. Every mobile node maintains the
binding between HoA and the CoA at the HA[ CITATION Che14 \l 1033 ].
