摘要
Abstract
LEO satellite networks can provide seamless real-time data communication for all kinds of users, which de-veloped rapidly in recent years. At the mean time, the massive payload data down-link system of space data sources, such as remote sensing satellites, still make use of traditional storage and forward mode. The real-time performance of space mission data will be improved effectively, if such satellites are connected to LEO satellite networks equipped with inter satellite links. However, it is necessary to design a specialized satellite network load balancing routing algorithm. Satellite parallel edge-disjoint multipath routing protocol (SPEMR) was designed for remote sensing satellite real-time down-link applications. OPNET simulation results indicate that the performance degradation index(DI) of the multipath scheme im-plemented by SPEMR is 0.32, which is only 32% of the TLR and 21% of the traditional DSP scheme. It is demonstrated that SPEMR has the better capability of transmitting massive data in real time.关键词
