As a Device-to-device (D2D) communication protocol, WiFi-Direct is chosen to enable the P2P data transmission between two parties. This work results in a cost-efficient, secure, SC-based, P2P, and Decentralized application (Dapp). Evaluations on performance of this Dapp is specified in terms of its D2D deployment, transaction costs, scalability, security, and privacy.enSmart ContractsBlockchainsEthereumPeer-to-peer ApplicationsPurchase and Rental ContractDecentralized Mobile ApplicationsText/Journal Article10.1515/itit-2017-00362196-7032
