Abstract

The invention discloses a BATMAN security routing method based on a blockchain-based satellite self-organizing network. At the beginning, the network is initialized, each satellite node generates a creation block, and an initial reputation value is assigned to each satellite node in the creation block ; Each satellite node periodically broadcasts an OGM packet message, and at the same time generates a class I block corresponding to the OGM packet message, and broadcasts it to the entire network; subsequently, the routing operation of the BATMAN protocol is performed according to the reputation value, and other satellite nodes are re-routed. Broadcast to complete secure routing. The invention can deal with route manipulation attack and the information communication problem of the whole network caused by it, and at the same time, can isolate or check the attacked nodes in time, and improve the performance of the whole network in terms of routing security.

Description

Blockchain-based satellite self-organizing network BATMAN secure routing method technical field The present invention relates to satellite routing field, be specifically related to a kind of satellite self-organizing network BATMAN security based on block chain. Full routing method. Background technique The transmission distance of satellite communication is long, and also can overcome the limitation of geographical location and bad weather, whether it is Satellite communication can be realized in cities and towns populated by human beings, or in sparsely populated mountainous areas or oceans with harsh environments. Its coverage is difficult to compare with the communication network on the ground. At the same time, in the face of severe earthquakes, tsunamis, etc. During natural disasters, satellites can also work normally and provide stable communications. The advantages of satellite communication in these aspects make it not With continuous development, it has ...
