Cost-efficient blockchain application to secure data transmission in heterogeneous FANETs

To guarantee the success of vehicular networks, it is essential to ensure that the communication process is reliable and safe from malicious actions and that the solution has low computational complexity and energy consumption. Therefore, the present work proposes a proof-of-concept solution to ensure crash fault-tolerant communication in emulated heterogeneous Flying Ad-Hoc Networks (FANETs) using the Proof of Elapsed Time (PoET) consensus algorithm through the Hyperledger Sawtooth blockchain framework.
