Distributed Ledger Technology for Smart Mobility: Variable Delay Models
This work addresses the lack of mathematical models for DAG-based DLTs, which is important for researchers and engineers developing feedback control systems in smart mobility.
The authors extend a fluid-based approximation for IOTA's DAG-based distributed ledger to incorporate variable transaction delays, validating it through simulations to support feedback control applications in smart mobility.
Recently, Directed Acyclic Graph (DAG) based Distributed Ledgers have been proposed for various applications in the smart mobility domain [1]. While many application studies have been described in the literature, an open problem in the DLT community concerns the lack of mathematical models describing their behaviour, and their validation. Building on a previous work in [1], we present, in this paper, a fluid based approximation for the IOTA Foundation DAG based DLT that incorporates varying transaction delays. This extension, namely the inclusion of varying delays, is important for feedback control applications (such as transactive control [2]). Extensive simulations are presented to illustrate the efficacy of our approach.
