Connectivity is an important key performance indicator and a focal point of research in large-
scale wireless networks. Due to path-loss attenuation of electromagnetic waves, direct …

Design of an efficient medium access control protocol is critical for proper functioning of a
distributed cognitive radio network and better utilization of the channels not being used by …

This paper investigates the problem of optimally determining source-destination connectivity
in random networks. Viewing the network as a random graph, we start by investigating the …

The clustering phenomenon is common in real world networks. A discrete-time network
model is proposed firstly in this paper, and then the phase clustering dynamics of the …

In this article, we develop a comprehensive analytical framework to characterize the area
spectral efficiency of a large scale Poisson cognitive underlay network. The developed …

The omnipresence of information cascading process in mobile social networking
applications makes the identification of a small set of influential users, which is widely …

In this paper, we use concepts and results from percolation theory to investigate and
characterize the effects of primaries on the connectivity of a secondary cognitive radio …

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 …

Proportional fair resource allocation plays a critical role to balance the spectrum efficiency
and fairness for cognitive orthogonal frequency division multiplexing (OFDM) network …

In this paper, we characterize the percolation condition for a continuum secondary cognitive
radio network under the SINR model. We show that the well-established condition for …
