ATCR: an adaptive time-based channel reservation mechanism for LEO satellite fixed cell systems

Résumé

In this paper, we propose an adaptive time-based channel reservation mechanism (ATCR) suitable for handover and call admission procedure control in future multiservices mobile satellite systems. These systems are characterized by a high rate of handover. While guaranteeing a null handover failure probability, by using a channel reservation strategy in the cells to be crossed by the user, ATCR optimizes the utilization of resources. The performance of our mechanism has been compared to other schemes. ATCR method has the advantage of a better channel utilization by sharing channels between users. An approximate analytical model has been developed, and its results have been validated through simulations.
