In this paper, a power optimization scheme based on user's reputation in non-orthogonal
multiple access (NOMA) Cognitive Radio Networks (CRN) is proposed. By combining NOMA …

In this paper, a downlink scenario of a non-orthogonal multiple access (NOMA) scheme with
power constraint via spectrum sensing is considered. Such network provides improved …

In this paper, we derive the throughput of non-orthogonal multiple access NOMA with
adaptive transmit power for cognitive radio networks (CRN). The secondary source and …

Recently, the combination of cognitive radio networks with the nonorthogonal multiple
access (NOMA) approach has emerged as a viable option for not only improving spectrum …

In this paper, a downlink security-aware resource allocation problem with delay constraint
via spectrum sensing is modeled as a mixed integer non-linear problem for non-orthogonal …

Recently, the combination of cognitive radio networks with the nonorthogonal multiple
access (NOMA) approach has emerged as a viable option for not only improving spectrum …

In this paper, the power allocation of Non-orthogonal multiple access (NOMA) for secondary
users in underlay cognitive radio is studied. In underlay cognitive radio networks, the …

One of the most challenging issues in non-orthogonal multiple access (NOMA) based
cognitive radio networks (CRNs) is the power allocation (PA) problem. Moreover, the quality …

In a conventional cognitive radio (CR) network, only when the primary user's (PU) frequency
bands are sensed to be free, secondary users (SUs) can utilize these frequency band …

The primary objective of cognitive radio network is to effectively utilize the unused spectrum
bands. In cognitive radio networks, spectrum sharing between primary and secondary users …
