Abstract:

A new satellite handover scheduling algorithm based on the maximum residual service time was proposed. The algorithm exploits both global positioning system (GPS) infrastructure and satellite diversity, providing a simple and real-time handover management in low earth orbit (LEO) satellite networks to minimize the expected number of satellite handovers. It reduces the users' call drop probability ultimately. Simulations were carried out on the typical Iridium satellite network and the simulation results corroborate the advantages gained by the proposed algorithm.

Key words: low earth orbit satellite networks, mobile satellite communications, handover, satellite diversity
