The channel of vehicle magnetic induction (VMI) communication is unexplored in the previous studies. To study such channel, we propose a vehicle antenna vibration model with Gaussian road disturbance inputs (GRDI) characterized by the boundary Chi-sq

The Internet of Things (IoT) is expected to connect a massive number of smart devices to the Internet. The existing centralized architecture for handling the huge volume of data created in the IoT is facing many research challenges, including securit

Caching at the network edge is regarded as a promising approach to handle content-dominated wireless traffic congestion problem and improve the quality of experience at mobile users (MUs). In this letter, we consider a heterogeneous wireless network

Magnetic Induction (MI) communication can be applied in some through-the-earth scenarios such as mines and underground rivers. To increase the transmission rate of MI communications, we propose a cooperative MI (CMI) scheme with an amplify-and-forwar

Physical transceiver impairments can degrade the performance of wireless communication systems significantly. Although partial impairments can be mitigated by some compensation algorithms, residual impairments still have substantial effects. In this

In this letter, we propose a link-addition strategy, called reduction structural hole (RSH), to enhance the network transport efficiency for scale-free networks. Instead of using global parameters of betweenness centrality and shortest path length th

This letter considers an efficient pilot scheme for two-way relay system with massive antennas in the relay base station (BS). For such a system, we prove that user terminals (UTs) in the same communication pair can reuse the pilot sequence without p

Based on complex network analysis and percolation theory, this letter proposes a method called LTPT to generate scale-free topology for wireless sensor networks (WSNs), with required connectivity and lifetime. The problem is divided into logical topo

We consider a large-scale cognitive radio network (CRN) in a Rayleigh fading environment. Errors of spectrum sensing by secondary users (SUs) are considered in the letter. Cumulative inter-network interference (between primary and secondary networks)

In this paper, complex network theory is used to generate robust scale-free topology for wireless sensor networks (WSNs). Nodes in WSNs consume energy in two stages: network generation and network operation. Existing scale-free models for WSNs focus
