Information Theory of Blockchain Systems
Quan-Lin Li, Yaqian Ma, Jing-Yu Ma +1
In this paper, we apply the information theory to provide an approximate expression of the steady-state probability distribution for blockchain systems. We achieve this goal by max…
Performance and Reliability Analysis for Practical Byzantine Fault Tolerance with Repairable Voting Nodes
Yan-Xia Chang, Qing Wang, Quan-Lin Li +1
The practical Byzantine fault tolerant (PBFT) consensus protocol is one of the basic consensus protocols in the development of blockchain technology. At the same time, the PBFT con…
Performance Evaluation, Optimization and Dynamic Decision in Blockchain Systems: A Recent Overview
Quan-Lin Li, Yan-Xia Chang, Qing Wang
With rapid development of blockchain technology as well as integration of various application areas, performance evaluation, performance optimization, and dynamic decision in block…
Dynamic Practical Byzantine Fault Tolerance and Its Blockchain System: A Large-Scale Markov Modeling
Yan-Xia Chang, Quan-Lin Li, Qing Wang +1
In a practical Byzantine fault tolerance (PBFT) blockchain network, the voting nodes may always leave the network while some new nodes can also enter the network, thus the number o…
A Markov Process Theory for Network Growth Processes of DAG-based Blockchain Systems
Xing-Shuo Song, Quan-Lin Li, Yan-Xia Chang +1
Note that the serial structure of blockchain has many essential pitfalls, thus a data network structure and its DAG-based blockchain are introduced to resolve the blockchain pitfal…
Tree Representation, Growth Rate of Blockchain and Reward Allocation in Ethereum with Multiple Mining Pools
Quan-Lin Li, Yan-Xia Chang, Chi Zhang
It is interesting but difficult and challenging to study Ethereum with multiple mining pools. One of the main difficulties comes from not only how to represent such a general tree…
SafetyNet: Safe planning for real-world self-driving vehicles using machine-learned policies
Matt Vitelli, Yan Chang, Yawei Ye +7
In this paper we present the first safe system for full control of self-driving vehicles trained from human demonstrations and deployed in challenging, real-world, urban environmen…
Stochastic Performance Modeling for Practical Byzantine Fault Tolerance Consensus in Blockchain
Fan-Qi Ma, Quan-Lin Li, Yi-Han Liu +1
The practical Byzantine fault tolerant (PBFT) consensus mechanism is one of the most basic consensus algorithms (or protocols) in blockchain technologies, thus its performance eval…
Infections Forecasting and Intervention Effect Evaluation for COVID-19 via a Data-Driven Markov Process and Heterogeneous Simulation
Quan-Lin Li, Chengliang Wang, Yiming Xu +5
The Coronavirus Disease 2019 (COVID-19) pandemic has caused tremendous amount of deaths and a devastating impact on the economic development all over the world. Thus, it is paramou…
A New Theoretical Framework of Pyramid Markov Processes for Blockchain Selfish Mining
Quan-Lin Li, Yan-Xia Chang, Xiaole Wu +1
In this paper, we provide a new theoretical framework of pyramid Markov processes to solve some open and fundamental problems of blockchain selfish mining under a rigorous mathemat…
Double-End Queues with Non-Poisson Inputs and Their Effective Algorithms
Heng-Li Liu, Quan-Lin Li, Yan-Xia Chang +1
It is interesting and challenging to study double-ended queues with First-Come-First-Match discipline under customers' impatient behavior and non-Poisson inputs. The system stabili…
Markov Processes in Blockchain Systems
Quan-Lin Li, Jing-Yu Ma, Yan-Xia Chang +2
In this paper, we develop a more general framework of block-structured Markov processes in the queueing study of blockchain systems, which can provide analysis both for the station…
Blockchain Queueing Theory
Quan-Lin Li, Jing-Yu Ma, Yan-Xia Chang
Blockchain has many benefits including decentralization, availability, persistency, consistency, anonymity, auditability and accountability, and it also covers a wide spectrum of a…
An Optimal LiDAR Configuration Approach for Self-Driving Cars
Shenyu Mou, Yan Chang, Wenshuo Wang +1
LiDARs plays an important role in self-driving cars and its configuration such as the location placement for each LiDAR can influence object detection performance. This paper aims…
