- Abstract
To solve the limited storage resource and the data storage reliability problem of Interplanetary Internet, a novel distributed storage strategy based on Raptor codes (DSSR) is proposed. According to the proposed strategy, source data packets are quickly transmitted to every node in the cluster by use of a directional random walk mechanism. The ID-based estimation method is used to estimate the global information at the pre-coding phase, the values are obtained without additional global information estimation phase. The reasonable procedure of XORing packets is designed so that the distribution of code degree tends to the ideal distribution. As presented by the analyses and simulations, random walk steps is greatly reduced compared with a relevant distributed storage strategy, while improving the decoding performance.
