Security Issues in Space Networks
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.
