A Load Balance Local LEO Satellite Network AP Selection Strategy

LEO satellites can serve as spatial extension of terrestrial network, introducing high-quality service through low latency and convenient access. The main challenge is the dynamicity causing by high relative speed between LEO satellites and terrestrial terminals. So how to make proper access point (AP) selection decision is a key problem. In this paper, we focus on AP selection problem, propose a local satellite AP selection strategy aiming at balancing the network load. We establish terminal coverage model and data transmission rate model for data collection and performance assessment. Results of comparative experiments show that the proposed strategy can balance the network load, lower handover frequency while maintaining well throughput expectation.
