Energy Efficient Resource Allocation in UAV-Enabled Mobile Edge Computing Networks
TL;DR: In this paper, the sum power minimization problem via jointly optimizing user association, power control, computation capacity allocation and location planning in a mobile edge computing (MEC) network with multiple unmanned aerial vehicles (UAVs).
Journal ArticleDOI
Joint Trajectory-Resource Optimization in UAV-Enabled Edge-Cloud System With Virtualized Mobile Clone
TL;DR: This article solves the complicated optimization problem through a block coordinate descent algorithm in an iterative way and can extend the endurance of the UAV and support reliable MC functions for GTs.
Journal ArticleDOI
Secure Wireless Communication in RIS-Aided MISO System With Hardware Impairments
TL;DR: This letter studies the robust transmission design for a reconfigurable intelligent surface (RIS)-aided secure communication system in the presence of transceiver hardware impairments and adopts the alternate optimization method to iteratively optimize one set of variables while keeping the other set fixed.
Journal ArticleDOI
Statistical CSI-Based Design for Reconfigurable Intelligent Surface-Aided Massive MIMO Systems With Direct Links
TL;DR: In this paper, the performance of RIS-aided massive MIMO systems with direct links is investigated, and the phase shifts of the RIS are designed based on the statistical channel state information (CSI).
Journal ArticleDOI
A Blockchain-Based Reward Mechanism for Mobile Crowdsensing
TL;DR: A novel blockchain-based MCS framework that preserves privacy and secures both the sensing process and the incentive mechanism by leveraging the emergent blockchain technology is proposed.
