Ad hoc network elastic transmission control method based on blockchain security attributes

Abstract

The invention discloses an ad hoc network elastic transmission control method based on blockchain security attributes. According to the ad hoc network elastic transmission control method, the advantages of the blockchain technology are combined, the data transmission behavior of the whole network is controlled based on a unified security attribute threshold of the whole network, and the problems of low transmission efficiency and the like caused by high dynamic and transmission intermittency of cluster network nodes in traditional end-to-end transmission are solved. A hop-by-hop transmission mode is combined with an environment perception and scheduling strategy, so that safe and flexible transmission and congestion control of heterogeneous nodes are realized, and the end-to-end transmission reliability of cluster data is ensured.

Description

technical field [0001] The present invention relates to the fields of block chain technology and network transmission technology, in particular to an ad hoc network elastic transmission control method based on block chain security attributes. Background technique [0002] Blockchain is a distributed database with features such as immutability, verifiability and traceability, and high security. First of all, immutability means that once the information is added to the blockchain, it cannot be tampered with by anyone. This is because the block needs to pass the consistency verification of all nodes in the system, so the modification of data on a single node is invalid. Secondly, verifiability and traceability means that each piece of information recorded in the block can verify its authenticity and reliability and track the source, because each piece of information in the block is stamped with a time stamp and has been recorded The data in the block cannot be tampered with, s...

Problems solved by technology

The transport layer of the traditional TCP / IP network architecture uses end-to-end reliable transmission based on the TCP protocol. It does not have a special security mechanism to ensure data security, and for a cluster network with dynamically changing network topology, the end-to-end path may It does not exist, and the routing path cannot be established at all times. If the TCP protocol of the traditional network is used, it will lead to possible information leakage and low efficiency of reliable transmission.

At the same time, the best-effort forwarding of the traditional network will cause packet loss when the link is interrupted, and the resource utilization of the intermittent link is low.
