When Data Fly: An Open Data Trading System in Vehicular Ad Hoc Networks

Communication between vehicles and their environment (i.e., vehicle-to-everything or V2X communication) in vehicular ad hoc networks (VANETs) has become of particular importance for smart cities. However, economic challenges, such as the cost incurred by data sharing (e.g., due to power consumption), hinder integration open systems into city applications, dynamic environmental zones. Moving from trading can address challenges incentivize vehicle drivers share data. In this context, integrating distributed ledger technology (DLT) is promising reducing transaction payments trading, avoiding dependencies on third parties, guaranteeing openness. because DLT conflicts with short available communication time fast moving objects VANETs, it remains unclear how VANETs using should be designed viable. work, we present a system design DLT. We measure required roadside unit real scenario estimate associated cost. Our results show that proposed technically feasible economically
