Distributed Ledger Technology Based Architecture for Decentralized Device-to-Device Communication Network

Abstract

Due to the mobility of devices, device-to-device (D2D) communication is a promising fifthgeneration (5G) technology in dynamic environments for improving message transmission efficiency for group communication. Additionally, all services in an ad hoc network are current Vehicle Ad Hoc Network (VANET) applications. Therefore, D2D communication has been introduced in ad hoc environments to reduce latency during vehicle conversations, such as autonomous vehicle solutions and drone fleet management for cellular vehicle-to-everything (C-V2X) modules and Internet of Drones (IoDs) networks. However, providing secure and effective group communication is an urgent challenge. To solve these problems, we propose a dynamic group management solution based on distributed ledger technology. This study demonstrates that a distributed ledger-based hierarchical architecture for dynamic group management is faster and more adaptable without compromising security and performance. Furthermore, the proposed method can facilitate the transfer of direct communication data without a centralized database, thereby reducing the chance of a single point of failure. In addition, the research was tested by a third party that has established close cooperation with world-leading automotive electronics suppliers in Taiwan.

Vehicles fleet communications in data infrastructure unavailability situations

“…A lot of literature exists on the topics of fleet communications and uncertain situations. Some papers are concentrating on the aspects which are influencing the communications performance [2], while others are describing various methods for planning each vehicle path under different uncertainties [3] or under changing environmentally conditions [4], for reducing the latency of the communication [5] It is presumed all the time that communication exists between any two vehicles in the fleet [6], [7] and also the distance between any two vehicles can be measured [8] There are cases when the vehicles fleet has to be deployed, but the infrastructure is not suitable, does not exist or is not an option to be implemented, either from technical or budget related reasons. An example of such a case would be a group of buildings (a factory or a campus) where the vehicles have to travel both inside the buildings and between them.…”
