Abstract

Aiming at the problem of low data transmission rate of traditional single path routing protocol in resource-constrai-ned LEO satellite network, based on GEO/LEO double-layer satellite network model, this paper proposed a new multi-path routing protocol(N-NCMR) for double-layer satellite network based on network coding(NC). Firstly, it used GEO satellite to calculate routing for LEO satellite network, and used NC technology to transmit different parts of data stream along multiple disjoint paths dynamically, thus it reduced the burden of LEO satellite. Secondly, this paper designed a delayed acknowledgement mechanism to accelerate data transmission. Source nodes could send subsequent groups continuously before receiving the previous set of acknowledgement(ACK) messages. The simulation results show that the proposed protocol significantly improves the throughput and data transmission efficiency of LEO satellite network.
