A Blockchain-Based Decentralized Wi-Fi Sharing Mechanism

Wi-Fi is widely used as an inexpensive way for terminal service access, which brings a trend of Wi-Fi sharing. However, the current Wi-Fi sharing mode has problems such as low reliability and high cost. In order to cope with these problems, this paper puts forward a decentralized Wi-Fi sharing mechanism based on blockchain, including three sub-mechanisms of Wi-Fi authentication, Wi-Fi sharing, and Wi-Fi usage charging. Specifically, Wi-Fi owners first authenticate their Wi-Fi information on the blockchain and only the authenticated Wi-Fi can be connected. Then, the Wi-Fi users pay for the Wi-Fi usage through the smart contracts. Finally, all transactions are registered on the blockchain to ensure the security and reliability of Wi-Fi sharing process. Simulation results show that the proposed mechanism keeps a high Wi-Fi sharing success rate of more than 97 percent at a high Wi-Fi request rate of 200 tps.
