    Norah M. Alshahrani1,2,*, M. L. Mat Kiah1,*, B. B. Zaidan3, A. H. Alamoodi4, Abdu Saif5

    CMC-Computers, Materials & Continua, Vol.75, No.2, pp. 2833-2858, 2023, DOI:10.32604/cmc.2023.036138

    Abstract A smart contract is a digital program of transaction protocol (rules of contract) based on the consensus architecture of blockchain. Smart contracts with Blockchain are modern technologies that have gained enormous attention in scientific and practical applications. A smart contract is the central aspect of a blockchain that facilitates blockchain as a platform outside the cryptocurrency spectrum. The development of blockchain technology, with a focus on smart contracts, has advanced significantly in recent years. However, research on the smart contract idea has weaknesses in the implementation sectors based on a decentralized network that shares an identical state. This paper extensively… More >

    A Novel IoT Application Recommendation System Using Metaheuristic Multi-Criteria Analysis

    Mohammed Hayder Kadhim, Farhad Mardukhi*

    Computer Systems Science and Engineering, Vol.37, No.2, pp. 149-158, 2021, DOI:10.32604/csse.2021.014608

    Abstract There are a variety of Internet of Things (IoT) applications that cover different aspects of daily life. Each of these applications has different criteria and sub-criteria, making it difficult for the user to choose. This requires an automated approach to select IoT applications by considering criteria. This paper presents a novel recommendation system for presenting applications on the IoT. First, using the analytic hierarchy process (AHP), a multi-layer architecture of the criteria and sub-criteria in IoT applications is presented. This architecture is used to evaluate and rank IoT applications. As a result, finding the weight of the criteria and sub-criteria… More >
