Multihop relay transmission in InterPlaNetary Internet based on fountain codes

To account for the problems of long delay, large loss, low SNR and no feedback information in IPN (InterPlaNetary Internet) backbone network, we proposed multihop relay protocols based on fountain codes. The rateless property, erasure property and no need feedback of fountain codes, which combined the advantage of relay make us propose the Random Linear Network Coding (RLNC) based and LT code based multihop relay protocols. We give the analysis and simulation results in transmission and delay of every protocol. The results indicate that we need to consider the residual energy, work mode and processing ability comprehensively in the selection of these protocols to realize the efficient and reliable transmission in the IPN backbone network.
