Paper Abstract

Due to the limited capacity of a single low earth orbit (LEO) satellite, the blocking probability of guaranteed handover (GH) algorithm increases rapidly in the case of high traffic load. In order to solve this problem, a novel handover scheme defined by multi-tier optimal layer selection is proposed. The scheme sufficiently takes into account the characteristics of the low/medium earth orbit (LEO/MEO) double-layer satellite network and the multimedia transmitted by such network, so it can effectively reduce the traffic load in the LEO which perform GH algorithm. The simulation results show that this approach integrated with GH algorithm used in LEO/MEO satellite network achieves a significant improvement in the QoS performance and practicability of the algorithm as compared to the single LEO layer network.
