Wireless Networks With RF Energy Harvesting: A Contemporary Survey
TLDR
This paper presents an overview of the RF-EHNs including system architecture, RF energy harvesting techniques, and existing applications, and explores various key design issues according to the network types, i.e., single-hop networks, multiantenna networks, relay networks, and cognitive radio networks.

Improving Wireless Physical Layer Security via Cooperating Relays
TLDR
Novel system designs are proposed, consisting of the determination of relay weights and the allocation of transmit power, that maximize the achievable secrecy rate subject to a transmit power constraint, or minimize the transmit powersubject to a secrecy rate constraint. Expand
Coalitional game theory for communication networks
TLDR
This article fills a void in existing communications literature, by providing a novel tutorial on applying coalitional game theory in communication networks through comprehensive theory and technical details as well as through practical examples drawn from both game theory and communication application.

TLDR
The proposed algorithms not only provide fair resource allocation among users, but also have a comparable overall system rate with the scheme maximizing the total rate without considering fairness, and have much higher rates than that of the scheme with max-min fairness. Expand
Wireless Charging Technologies: Fundamentals, Standards, and Network Applications
TLDR
This paper presents a comprehensive overview of wireless charging techniques, the developments in technical standards, and their recent advances in network applications, and discusses open issues and challenges in implementing wireless charging technologies. Expand

  • 5 June 2011
TLDR
Simulation results show that the proposed algorithm yields a reduction in terms of the average power losses (over the distribution line) per micro-grid, reaching up to 31% improvement relative to the non-cooperative case. Expand
A trust evaluation framework in distributed networks: Vulnerability analysis and defense against attacks
TLDR
Simulations show that the proposed framework to quantitatively measure trust, model trust propagation, and defend trust evaluation systems against malicious attacks can significantly improve network throughput as well as effectively detect malicious behaviors in ad hoc networks. Expand
