A Blockchain-Powered Traffic Management System for Unmanned Aerial Vehicles

Abstract

The increasing popularity and usage of unmanned aerial vehicles (UAVs) has brought about new challenges in airspace management. With the number of drones expected to grow even further in the coming years, there is an urgent need for an autonomous traffic management system (TMS) that can safely and effectively manage drone traffic in the airspace. It is critical that this TMS be built with principles of the Confidentiality, Integrity, and Availability (CIA) triad. In this paper, a traffic management system for UAVs is presented that takes advantage of a Hyperledger Fabric blockchain network. The TMS provides a decentralized and secure method to manage and deconflict drone flight paths, allowing for safe navigation in crowded airspaces. Through a series of simulated experiments, we demonstrated the system’s capabilities in handling path creation, multiple conflict resolutions, and large numbers of drones. Simulated tests showed that the proposed system was able to handle deconfliction of 1000 drones inside of a one square kilometer, and returned calculated paths for drones in 60 to 2000 ms with up to 100 deconflictions. The Hyperledger Fabric powered traffic management system showcased the potential to leverage permissioned blockchain technology in improving drone traffic management.

Information Sharing in Land Registration Using Hyperledger Fabric Blockchain

“…The Hyperledger Fabric network involves various nodes, each of them uses an identity that is presented by the Membership Service Provider to enroll users [35,62,64]. The ledger can be divided into the world state, which is a database that contains the last up-to-date values of the object properties, and the blockchain, which is a log of transactions that holds all of the historical values in the form of connected blocks [65]. Each node possesses a ledger copy that is updated by the nodes via a consensus mechanism, which guarantees that all nodes have the same ledger copy [65,66].…”

“…The ledger can be divided into the world state, which is a database that contains the last up-to-date values of the object properties, and the blockchain, which is a log of transactions that holds all of the historical values in the form of connected blocks [65]. Each node possesses a ledger copy that is updated by the nodes via a consensus mechanism, which guarantees that all nodes have the same ledger copy [65,66]. A consensus is achieved through practical Byzantine fault tolerance agreement (PBFT) [67]; however, sometimes, Hyperledger Fabric also allows no consensus [8,68].…”

“…The chaincode constitutes a collection of smart contracts. Each of these contracts encapsulates executable logic responsible for generating new records that are subsequently appended to the ledger [65]. A smart contract establishes the operational rules between different organizations in an executable code [53].…”

A Novel Model-Free Adaptive Proportional–Integral–Derivative Control Method for Speed-Tracking Systems of Electric Balanced Forklifts

“…In recent years, autonomous driving technology has seen rapid advancements and demonstrated remarkable achievements in various fields, including smart cars [2,3], unmanned aerial vehicles [4,5], and rail transportation [6,7]. However, when it comes to electric balanced forklifts, the practical application of autonomous driving is still in its early stages.…”
