Resource allocation plays a critical role to enhance the performance of cognitive orthogonal
frequency division multiplexing (OFDM) network. However, due to lack the cooperation …

Accurate and efficient detection of the radio-frequency spectrum is a challenging issue in
wireless sensor networks (WSNs), which are used for multi-channel cooperative spectrum …

We consider, in this paper, the maximization of throughput in a dense network of
collaborative cognitive radio (CR) sensors with limited energy supply. In our case, the …

We consider the problem of communication allocation for remote state estimation in a
cognitive radio sensor network (CRSN). A sensor collects measurements of a physical plant …

提出了一种新的加权距离测度. 首先, 对每个感知用户进行证据提取. 然后 …

Wireless sensor networks (WSNs) typically use license-free industrial, scientific, and medical
frequency bands, and by increasing the demand for different usages of WSNs, it is …

In this letter, a novel metric is proposed to evaluate the average sensing energy-efficiency of
cognitive radio (CR) networks. A theorem as well as the related closed-form expression for …

Wireless sensor networks (WSNs) have been deployed for many applications of target
detection, such as intrusion detection and wildlife protection. In these applications, the first …

The most commonly used spectrum sensing techniques in cognitive radio (CR) networks,
such as the energy detector (ED), matched filter (MF), and others, suffer from the noise …

The visiting and less-privileged status of the secondary users (SUs) in a cognitive radio
network obligates them to release the occupied channel instantly when it is reclaimed by the …
