ETRA: Efficient Three-Stage Resource Allocation Auction for Mobile Blockchain in Edge Computing

摘要

Blockchain technology is emerging in various fields, to guarantee security of digital currency and internet of things. In this paper, we provide incentive to encourage edge servers to serve mobile users for the mobile blockchain application. We formulate the problem as a resource allocation problem, then we propose a three-stage auction to implement resource allocation specially designed for mobile blockchain, and introduce the group-buying mechanism to motivate mobile users. We prove that our auction scheme is truthful, individual rationality, and computational efficiency. We compare proposed scheme with TACD and HAF mechanisms, and simulation results show that the social welfare achieved by our scheme is higher than that of TACD and HAF mechanisms.
