In 2009, Chen et al. proposed a satellite communication system for mobile devices to achieve wide communication. In this scheme, there are some security loopholes that need to be fixed since the mobile device was stolen. Since a malicious attacker intercepts the mobile user’s information they can proceed with different attacks. Hence, we propose a novel scheme to improve the mobile user’s commu...

In this article, design and analysis of an optimal orbit control for a communication satellite is investigated. It is the challenging task and critical importance to control the orbit of a communication satellite especially the one used for worldwide communication. The main objective of this work is to evolve a design based on modelling and simulation of an optimal orbit controller for a satell...

Satellite communication promises potential methods for providing global communication. In particular, by the development of a Low Earth Orbital (LEO) satellite constellation, both global coverage and broadband communication will be accessible. Problems arise in situations where various tra¢ c types in broadband communication require di¤erent levels of quality of service (QoS). Tra¢ c control is...

Low Earth Orbit (LEO) satellites are used for public networking and for scientific purposes. Communication via satellite begins when the satellite is positioned in its orbital position. Ground stations can communicate with LEO satellites only when the satellite is in their visibility region. The duration of the visibility and the communication vary for each LEO satellite pass over the station, ...
