With the overwhelming demand for wireless devices, cognitive radios (CRs) have been
envisioned to be applied in the vehicular communications in the near future. In the moving …

Most of traditional power allocation algorithms are often based on maximum capacity
technology (MCT) in cognitive radio networks (CRNs) at the expense of higher energy …

In most of the existing works on cognitive radio (CR) systems, the multi-user OFDMA system
how to realize the reasonable allocation of sub-carriers and power is one of the key. In this …

Following the characteristics of the cognitive radio (CR) and the exponential increase of the
vehicles, it is envisioned to deploy CR in vehicular ad‐hoc network (VANET) in near future …

In this paper, we introduce a hybrid strategy which combines pattern search (PS)
optimization and genetic algorithm (GA) to address the problem of power allocation in …

Both spectrum sensing and power allocation have crucial effects on the performance of
wireless cognitive ad hoc networks. In order to obtain the optimal available subcarrier sets …

In this paper, we investigate the problem of power allocation in cognitive underlay networks,
where a secondary user (SU) is allowed to coexist with a primary user (PU). We consider …

In cognitive radio networks, the secondary users perceive the spectrum and access it to data
transmission when the primary users are absent. Then in the cognitive radio enabled …

This paper considers optimal resource allocation in integrated framework of cognitive radio
and ad hoc network. The design problem looks for an optimal solution in power and channel …

One of the key problems in orthogonal frequency division multiple-access (OFDMA)
cognitive radio (CR) ad hoc networks is to efficiently and fairly allocate subcarriers and …
