Proceedings ArticleDOI

Physical Layer Security for Two Way Relay Communications with Friendly Jammers

TL;DR: It is found that a non-zero secrecy rate is indeed achievable in this two-way relay network even without external jammers and an optimal solution of jamming power allocation is provided for the system with friendly jammers.
Journal ArticleDOI

Low complexity resource allocation with opportunistic feedback over downlink OFDMA networks

TL;DR: Two constant complexity limited-feedback algorithms are proposed to achieve near-optimal performance and reduce the required feedback overhead significantly, and achieve constant computational complexity with little performance loss compared to the optimal solution.
Journal ArticleDOI

A Bayesian Overlapping Coalition Formation Game for Device-to-Device Spectrum Sharing in Cellular Networks

TL;DR: A hierarchical matching algorithm is proposed which can detect whether the sufficient condition is satisfied and, if it is satisfied, achieve a stable and unique matching structure which coincides with the overlapping coalition agreement profile in the core of the BOCF game.
Proceedings ArticleDOI

Trust modeling and evaluation in ad hoc networks

TL;DR: An information theoretic framework to quantitatively measure trust and model trust propagation in ad hoc networks and develops Axioms that address the basic rules for trust propagation.
Journal ArticleDOI

Socially Optimal Queuing Control in Cognitive Radio Networks Subject to Service Interruptions: To Queue or Not to Queue?

TL;DR: To bridge the gap between the individually and socially optimal strategies, a pricing mechanism is proposed to toll the service of each secondary customer, thus equalizing the two optimal strategies.
