Blockchain based data transmission control for tactical data link

Abstract

Tactical Data Link (TDL) is a communication system that utilizes a certain message format and a protocol to transmit data via wireless channels in an instant, automatic, and secure way. So far, TDL has shown special importance in military applications. Current TDL adopts a distributed architecture to enhance anti-destruction capacity. However, TDL faces the problem of data inconsistency and thus cannot well support cooperation across multiple militarily domains. To tackle this problem, we propose to leverage blockchain to build an automatic and adaptive data transmission control mechanism for TDL. It achieves automatic data transmission and realizes information consensus among TDL consensus nodes. Besides, smart contracts based on blockchain further enable adjusting data transmission policies automatically. The experimental results illustrate effectiveness and efficiency of our proposed blockchain based data transmission control for TDL.
