Abstract
Third generation (3G) communication networks based on low Earth orbit (LEO) satellites provide a new trend in future mobile communications. LEO satellites provide lower end-to-end delays and efficient frequency spectrum utilization, making it suitable for personal communication services (PCS). However, ongoing communications using LEO satellite systems experience frequent handover due to high rotational speed of satellites. In this paper, we provide a comprehensive literature survey on proposed handover schemes for LEO satellite systems. We also present a detailed classification of handover schemes in the literature. Finally, we compare the handover schemes using different quality of service
