Cooperative spectrum sensing schemes with partial statistics knowledge
Juan Augusto Maya, Leonardo Rey Vega, Cecilia G. Galarza
In this letter, we analyze the problem of detecting spectrum holes in cognitive radio systems. We consider that a group of unlicensed users can sense the radio signal energy, perfo…
Exploiting Spatial Correlation in Energy Constrained Distributed Detection
Juan Augusto Maya, Cecilia G. Galarza, Leonardo Rey Vega
We consider the detection of a correlated random process immersed in noise in a wireless sensor network. Each node has an individual energy constraint and the communication with th…
On Fundamental Trade-offs of Device-to-Device Communications in Large Wireless Networks
Andrés Altieri, Pablo Piantanida, Leonardo Rey Vega +1
This paper studies the gains, in terms of served requests, attainable through out-of-band device-to-device (D2D) video exchanges in large cellular networks. A stochastic framework,…
Cooperative Strategies for Interference-Limited Wireless Networks
Andres Altieri, Leonardo Rey Vega, Cecilia G. Galarza +1
Consider the communication of a single-user aided by a nearby relay involved in a large wireless network where the nodes form an homogeneous Poisson point process. Since this netwo…
