Fast-Fading Channel and Power Optimization of the Magnetic Inductive Cellular Network
Honglei Ma, Erwu Liu, Zhijun Fang +4
The cellular network of magnetic Induction (MI) communication holds promise in long-distance underground environments. In the traditional MI communication, there is no fast-fading…
Blockchain Based Zero-Knowledge Proof of Location in IoT
Wei Wu, Erwu Liu, Xinglin Gong +1
With the development of precise positioning technology, a growing number of location-based services (LBSs) facilitate people's life. Most LBSs require proof of location (PoL) to pr…
Balancing Performance and Cost for Two-Hop Cooperative Communications: Stackelberg Game and Distributed Multi-Agent Reinforcement Learning
Yuanzhe Geng, Erwu Liu, Wei Ni +5
This paper aims to balance performance and cost in a two-hop wireless cooperative communication network where the source and relays have contradictory optimization goals and make d…
Dual-Segment Clustering Strategy for Hierarchical Federated Learning in Heterogeneous Wireless Environments
Pengcheng Sun, Erwu Liu, Wei Ni +6
Non-independent and identically distributed (Non- IID) data adversely affects federated learning (FL) while heterogeneity in communication quality can undermine the reliability of…
SNR Maximization and Localization for UAV-IRS-Assisted Near-Field Systems
Hanfu Zhang, Yidan Mei, Erwu Liu +1
This letter introduces a novel unmanned aerial vehicle (UAV)-intelligent reflecting surface (IRS) structure into near-field localization systems to enhance the design flexibility o…
A SER-based Device Selection Mechanism in Multi-bits Quantization Federated Learning
Pengcheng Sun, Erwu Liu, Rui Wang
The quality of wireless communication will directly affect the performance of federated learning (FL), so this paper analyze the influence of wireless communication on FL through s…
