At present, we are in the 5G wireless technology era, where the implementation is being rolled out, and work is still going on. The next technological advance, according to G+ trends, is 6G, and work on it has already started. Although the work is still being carried out, the expected technologies, advancements, challenges, and opportunities. One such key aspect of 6G is privacy and trust while handling high-level, data-intensive applications. Making 6G a general-purpose and useful technology presents a challenge and a pillar of wireless technology for the upcoming years. This paper investigates how this can be accomplished using blockchain technology and an appropriate consensus algorithm for an anticipated 6G user case: smart infrastructure/Internet of vehicles, an intelligent transport system that can communicate over blockchain in a 6G-like environment. The entire work has been done over Ethereum, and 6G-type conditions have been replicated using a network simulator. The work demonstrates how blockchain can lead to enhanced data security, and an efficient and reliable consensus for practical purposes. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Aiming at the Byzantine fault-tolerant consensus algorithm when the number of nodes is too large, there are problems such as a large amount of data exchange, slow consensus speed, and security degradation caused by proxy nodes, based on threshold signatures, a new Byzantine fault-tolerant consensus algorithm based on local temporary consensus and global confirmation is proposed. Nodes divide into different zones based on their geographical location, the algorithm conducts temporary consensus among zones in parallel, and all nodes participate in global confirmation together, reducing the amount of network data exchange during the consensus process while improving consensus speed and security. © 2024 IEEE.

Cryptocurrencies, such as Bitcoin and Ethereum, are digital currencies operating on a peer-to-peer network. Cryptocurrencies rely on consensus algorithms for transaction validation and network security. Ethereum recently replaced its proof-of-work (PoW) consensus algorithm with a proof-of-stake (PoS) algorithm on September 15, 2022. This research aims to study the following research question: Does changing from PoW to PoS consensus increase price and transaction volume? To answer this question, we implemented synthetic control methods to compare the pre- and post-treatment trends of the price and volume of Ethereum against a synthetic counterfactual. The result of our analysis suggests that Ethereum shifting from PoW to PoS had a positive effect on its price and a non-significant negative effect on transaction volume. Price increasing relative to the synthetic counterfactual is promising for convincing other PoW blockchains that a switch to PoS may lead to increased investment opportunities while decreasing the environmental impact. © 2023 29th Annual Americas Conference on Information Systems, AMCIS 2023.

Consistent state of the system is the basis of reaching the target area at the same time in rendezvous of multi-UAV, and consensus algorithm is an effective method of multi-UAV system to achieve a consistent state. In order to shorten the convergence time of system state, on the base of the mathematical model of multi-UAV rendezvousing problem, the basic consensus algorithm and the consensus algorithm based on the past state difference have been improved. A new fast consensus algorithm was designed with a parameter, and theorems about efficiency and convergence of the new algorithm were mathematically proved. Simulation results verify the effectiveness and feasibility of the new algorithm. © 2015 IEEE.

The polar region communication network is modeled as a delay-tolerant payment channel network and a multi-path routing system is assumed to operate. Among the most appropriate models for sharing and managing such collected scientific and technological information, a distributed ledger-based information distribution service model would be one. In this paper, we analyzed the delay-tolerant payment channel network based on a partially Δ-synchronized blockchain model. In this study, we analyze how communication network delay can affect the delay-tolerant payment channel protocol. For the security transfer analysis of the blockchain-to-blockchain consensus algorithm, we assume that the protocol including slashing operates in a partially Δ-synchronous and permission-less setting. This paper proposes upper bounds of the attacker's share and safe areas according to private attacks in a delay-tolerant communication network situation. © 2024 IEEE.

Blockchain ensures data consistency and security through consensus algorithms. The PBFT is a consensus mechanism frequently applied in consortium blockchains. However, PBFT encounters performance bottlenecks when handling a substantial number of nodes, thereby significantly constraining its applicability in blockchain systems. This paper proposes an enhanced PBFT algorithm called RT-PBFT. The algorithm designs a reputation model to assess the credibility of nodes, then groups nodes based on the evaluation results, and subsequently divides the consensus process into intra-group and inter-group consensus, thus improving overall consensus efficiency. Additionally, a threshold signature mechanism is incorporated to optimize intra-group consensus, effectively reducing the communication overhead among nodes. The performance of RT-PBFT algorithm is verified through comparative experiments with traditional PBFT and G-PBFT algorithm. The experimental results demonstrate that the RT-PBFT algorithm reduces transaction latency and enhances throughput. © 2024 IEEE.

Multi-agent systems presently find extensive applicability across diverse domains. Central to these applications is the imperative for agents to exchange information regarding their experiences, knowledge, and actions. Distributed algorithms, denoting algorithms employed by multiple agents within a system to collaboratively execute a particular task, play a pivotal role. Within multi-agent systems, these algorithms facilitate the coordination of agents that are typically autonomous and possess decision-making capabilities. Given the diverse communication graph structures and communication challenges inherent in multi-agent systems employing distributed algorithms, agents necessitate a consensus phase. Conversely, the implementation of distributed algorithms within graphs featuring a substantial number of edges can exert significant strain on the limited resources of wireless nodes. This study proposes a gossip algorithm as a viable solution to the requirement for consensus among agents engaged in decentralized decision-making within multi-agent systems. The suggested algorithm reduce the graph through its scoring structure and fosters consensus among agents via the ranked gossip structure constructed upon this graph. Through simulation studies, the feasibility and effectiveness of the proposed algorithm across varied graph structures are demonstrated. © 2024 IEEE.

This article proposes a new formulation for walking behavior of a group of autonomous robots that adopts socio-dynamic capabilities of a pedestrian crowd. The socio-dynamic capabilities here mean the ability to receive position information from the other robots, to follow the behavior of the group without compromising its safety. The socio-dynamic behavior which will be implemented in the robot group adopted from the model of human walking behavior in a pedestrian crowd, which is known as Social Force Model (SFM). In this research, factors contained in SFM will be induced into a consensus algorithm and then will be implemented into a group of humanoid robots. The aim of the integration of SFM into consensus algorithm is to create a group of robots that are capable of carrying out its collective tasks while still able to maintain its safety. The attractive feature of the proposed algorithm is the fact that robots are still back to the formation after it avoid obstacle. Simulation and experiment results show the effectiveness of the proposed algorithm. Experiments were performed in this research is the first consensus algorithm implementation on a group of humanoid robot.

Traditional droop control is incapable of achieving precise frequency and voltage regulation, as well as dealing with power imbalance issue caused by inconsistent line impedance in distributed generator (DG) systems. Therefore, an improved droop control strategy is proposed in this paper. The improved strategy solving the two problems using consensus algorithm and coefficient adaptation. First, by constructing dynamic droop coefficients, the method adaptively adjusts frequency and voltage. This ensures accurate frequency and voltage regulation with zero steady-state error in the system. Additionally, a reactive power deviation term is constructed to depict deviation level of each DG in the system. Utilizing the consensus algorithm, reactive power deviation terms lead to zero in the end and precise distribution of reactive power is achieved. Simulation experiments are conducted on the MATLAB/Simulink platform to validate the effectiveness of the proposed control strategy.

Distributed control for multiple hybrid energy storage systems using consensus algorithm in direct current power supply system

Multiple hybrid energy storage systems (multi-HESSs) consisting of batteries and supercapacitors (SCs) is widely used to share the requirement of system pulsating power, reducing the dependence on a single hybrid energy storage system (HESS) to improve the system reliability. The filter composed of virtual resistance droop control (VRDC) and virtual capacitance droop control (VCDC) in a HESS can achieve frequency distribution of pulsating power between a battery and SC. However, it suffers from the output voltage deviation and terminal voltage variation. Mismatched line impedances and different system parameters can cause different output voltages and inaccurate current sharing in the multi-HESSs. Meanwhile, the differences in the terminal voltages of SCs can affect the transient output capability. Therefore, this paper proposes a consensus-based distributed control strategy (CDCS) for multi-HESSs, which not only achieves global average output voltage and current sharing for batteries but also realizes restoration and consistency of SCs terminal voltage. The state variable information of adjacent converters for multi-HESSs is exchanged by the sparse communication network, and the steady-state analysis of state variables is proved. The direct current (DC) power supply system with four HESSs is established to verify the effectiveness of the proposed control strategy.
