    A Blockchain-Based Game Approach to Multi-Microgrid Energy Dispatch

    Zhikang Wang#, Chengxuan Wang#, Wendi Wu, Cheng Sun, Zhengtian Wu*

    CMES-Computer Modeling in Engineering & Sciences, Vol.138, No.1, pp. 845-863, 2024, DOI:10.32604/cmes.2023.029442

    Abstract As the current global environment is deteriorating, distributed renewable energy is gradually becoming an important member of the energy internet. Blockchain, as a decentralized distributed ledger with decentralization, traceability and tamper-proof features, is an important way to achieve efficient consumption and multi-party supply of new energy. In this article, we establish a blockchain-based mathematical model of multiple microgrids and microgrid aggregators’ revenue, consider the degree of microgrid users’ preference for electricity thus increasing users’ reliance on the blockchain market, and apply the one-master-multiple-slave Stackelberg game theory to solve the energy dispatching strategy when each market entity pursues the maximum revenue.… More >

    A Secure Microgrid Data Storage Strategy with Directed Acyclic Graph Consensus Mechanism

    Jian Shang1,2,*, Runmin Guan2, Wei Wang2

    Intelligent Automation & Soft Computing, Vol.37, No.3, pp. 2609-2626, 2023, DOI:10.32604/iasc.2023.037694

    Abstract The wide application of intelligent terminals in microgrids has fueled the surge of data amount in recent years. In real-world scenarios, microgrids must store large amounts of data efficiently while also being able to withstand malicious cyberattacks. To meet the high hardware resource requirements, address the vulnerability to network attacks and poor reliability in the traditional centralized data storage schemes, this paper proposes a secure storage management method for microgrid data that considers node trust and directed acyclic graph (DAG) consensus mechanism. Firstly, the microgrid data storage model is designed based on the edge computing technology. The blockchain, deployed on… More >

    Cross-Domain Data Traceability Mechanism Based on Blockchain

    Shoucai Zhao, Lifeng Cao*, Jinhui Li, Jiling Wan, Jinlong Bai

    CMC-Computers, Materials & Continua, Vol.76, No.2, pp. 2531-2549, 2023, DOI:10.32604/cmc.2023.040776

    Abstract With the application and development of blockchain technology, many problems faced by blockchain traceability are gradually exposed. Such as cross-chain information collaboration, data separation and storage, multi-system, multi-security domain collaboration, etc. To solve these problems, it is proposed to construct trust domains based on federated chains. The public chain is used as the authorization chain to build a cross-domain data traceability mechanism applicable to multi-domain collaboration. First, the architecture of the blockchain cross-domain model is designed. Combined with the data access strategy and the decision mechanism, the open and transparent judgment of cross-domain permission and cross-domain identity authentication is realized.… More >

    Blockchain-Based Secure and Fair IoT Data Trading System with Bilateral Authorization

    Youngho Park1, Mi Hyeon Jeon2, Sang Uk Shin3,*

    CMC-Computers, Materials & Continua, Vol.76, No.2, pp. 1871-1890, 2023, DOI:10.32604/cmc.2023.039462

    Abstract These days, data is regarded as a valuable asset in the era of the data economy, which demands a trading platform for buying and selling data. However, online data trading poses challenges in terms of security and fairness because the seller and the buyer may not fully trust each other. Therefore, in this paper, a blockchain-based secure and fair data trading system is proposed by taking advantage of the smart contract and matchmaking encryption. The proposed system enables bilateral authorization, where data trading between a seller and a buyer is accomplished only if their policies, required by each other, are… More >

    An Incentive Mechanism Model for Crowdsensing with Distributed Storage in Smart Cities

    Jiaxing Wang, Lanlan Rui, Yang Yang*, Zhipeng Gao, Xuesong Qiu

    CMC-Computers, Materials & Continua, Vol.76, No.2, pp. 2355-2384, 2023, DOI:10.32604/cmc.2023.034993

    Abstract Crowdsensing, as a data collection method that uses the mobile sensing ability of many users to help the public collect and extract useful information, has received extensive attention in data collection. Since crowdsensing relies on user equipment to consume resources to obtain information, and the quality and distribution of user equipment are uneven, crowdsensing has problems such as low participation enthusiasm of participants and low quality of collected data, which affects the widespread use of crowdsensing. This paper proposes to apply the blockchain to crowdsensing and solve the above challenges by utilizing the characteristics of the blockchain, such as immutability… More >
