Improving Wireless Physical Layer Security via Cooperating Relays
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
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.

  • 5 June 2011
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
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
