Abstract

In low Earth orbit mobile satellite systems (LEO MSS), the very high frequency of handovers during a call's lifetime will strongly influence the system capacity and performance. In this paper, a novel and efficient traffic dependent dynamic channel allocation and reservation (TDDCAR) scheme is proposed and its performance is evaluated and compared with several existing channel resource management strategies. To effectively reduce the handover failure probability, the proposed TDDCAR scheme estimates the number of handover requests then assigns or releases the channels for reservation based on the evaluation of certain dynamic channel allocation (DCA) cost functions. The performance evaluation results have clearly shown that the TDDCAR scheme can significantly improve the system performance and it is an excellent handover strategy candidate for LEO MSS.
