Cognitive radio is a practical solution for spectrum scarcity. In cognitive networks, unlicensed
(secondary) users should sense the spectrum before any usage to make sure that the …

In this paper, a novel compressed sensing (CS) acquisition and joint recovery of
spatiotemporal correlated signals algorithm is presented for effective data collection and …

In the context of spectrum sensing in cognitive radio networks, collaborative spectrum
sensing has been proposed as a way to overcome multipath and shadowing, and hence …

The WSNs are developed to sense, gather, process and transmit the real-world information
and so in recent years, solving numerous challenges of wireless sensor networking are …

In Cognitive Radio systems, using spatial-frequency opportunistic reuse is emerged
interestingly by constructing and deploying spatial-frequency PSD maps. Since the CR …

In context aware wireless multimedia sensor networks, scenarios are usually such that
signals of multiple distributed sensors contain a common sparse component and each …

Spectrum resources management of growing demands is a challenging problem and
Cognitive Radio (CR) known to be capable of improving the spectrum utilization. Recently …

In Wireless Sensor Networks, and especially in Wireless Multimedia Sensor Networks,
scenarios are usually such that the signals acquired by various distributed sensors contain a …
