Abstract :
This paper deals with the performance evaluation of different channel resource management techniques in low Earth orbit (LEO) satellite systems based on an Earth-fixed cell concept. Both fixed and mobile users have been considered resulting in several classes of users. Each class requires a given quality of service (QoS) and thus a fixed part of the shared resource. Two channel allocation techniques have been investigated: fixed channel allocation (FCA) and dynamic channel allocation (DCA). An analytical model has been derived to analyse the performance of the FCA scheme supporting different kinds of users. A performance comparison of FCA and DCA strategies has also been carried out by simulations as regards the blocking probabilities of each type of users
