Performance and Capacity Consistency Analysis of A Wireless UAV-Blockchain System

Blockchain is widely applied in the field of Unmanned Aerial Vehicles (UAVs) for its characteristics of high distribution, secure data exchange and storage. Different from the current blockchain systems that are mostly deployed on a wired network, this paper proposed a wireless UAV-blockchain system. Each UAV node acts as a blockchain node and has onboard functionality of performing transactions interactions and consensus mechanisms via wireless ad-hoc channels. We study the interactions between the UAV ad hoc network capacity and the blockchain system, and evaluate the performance (transactions per second) under corresponding all possible network coverage probabilities. Performance evaluations are presented to testify the theoretical analysis, which shows how the UAV-blockchain system throughput is affected by the block arrival rate and UAV network scale.
