Abstract--Satellites are being used to capture real-time images,
video for various purposes, such as, observing the Earth, weather
data, live images for tornado, cyclones, tsunami, etc. In future,
these data can be accessed by terrestrial users through the
Internet. Mobility protocols aim at providing uninterrupted real-
time data communication facilities through seamless Internet
connectivity to hosts or networks in motion, such as in bus, train,
aircraft, and satellites. Mobile IP is an example of such a mobility
protocol which uses Home Agent for mobility management, and
requires signaling among the mobility agents, mobile node and
the correspondent node for its operation. Originally, Mobile
IP had no route optimization between end hosts; all traffic
passes the mobility agents. However, recent mobility protocols,
such as, Mobile IPv6 incorporated Route Optimization between
end hosts, by informing correspondent node and home agent
