Energy Efficient Maximal Throughput Resource Scheduling Strategy in Satellite Networks

In this letter, a greedy routing strategy is proposed for resource scheduling in Earth observation mission to achieve the maximum throughput and improve energy efficiency. Resource time-expanded graph (RTEG) introduced depict time-evolving topology resources of satellite networks. Based on RTEG, an efficient allocation algorithm (EERA) designed reduce total consumption maximize data transmission by properly transceiver resource, storage power satellites. Simulation results show that EERA achieves preferred efficiency when reaching throughput.
