Design of Routing Incentive Protocol for Space Network Based on Blockchain Technology

The global commercialization of satellites has intensified, and the types and numbers of new spacecrafts have increased year by year. However, the repeated functional construction and “islandization” characteristics of spacecraft severely restrict the use efficiency of space resources. How to realize the open interconnection and self-adaptation optimization cooperation of satellite resources and encourage more and more on-orbit spacecrafts to share spatial data services and routing resources is a severe challenge for the new generation space network communication protocol. This paper builds the Incentive Protocol of Routing based on the TCP/IP protocol family under the CCSDS spatial communication protocol standard framework. Using blockchain distributed database technology and consensus mechanism, combined with routing flow identification technology, design, and implement a network route incentive protocol and game model based on spacecraft route contribution proof consensus mechanism, intended to provide a feasible technical framework and feasible solution for the construction of the integrated digital intelligent economic ecology of the world.
