Abstract Wireless Multimedia Sensor Networks (WMSNs) have drawn tremendous attention
because of their potential impact on scientific research and their numerous attractive …

In this paper, dynamic spectrum access (DSA) in multi-channel cognitive radio networks
(CRNs) is studied. The two fundamental issues in DSA, spectrum sensing and spectrum …

In cognitive radio networks (CRNs), secure information transfer is of paramount importance
for primary users (PUs), while secondary users (SUs) mainly desire to ease the starvation for …

In this paper, we investigate the opportunistic spectrum access for cognitive radio vehicular
ad hoc networks. The probability distribution of the channel availability is first derived …

Network coding and opportunistic routing are two recognized innovative ideas to improve
the performance of wireless networks by utilizing the broadcast nature of the wireless …

In this paper, risk-aware cooperative spectrum access schemes for cognitive radio networks
(CRNs) with multiple channels are proposed, whereby multiple primary users (PUs) …

Cooperative routing and spectrum aggregation are two promising techniques for Cognitive
Radio Ad-Hoc Networks (CRAHNs). In this paper, we propose a spectrum aggregation …

Cognitive radio networks (CRNs) have been emerging as a promising technique to improve
the spectrum efficiency of wireless and mobile networks, which form spectrum clouds to …

In cognitive radio ad hoc networks (CRAHNs), the secondary users' links are interrupted by
the arrival of primary users, which leads to a significant increase of the number of …
