In the past decade, cognitive radio and cooperative communication techniques have been
proposed in the literature for efficiently utilizing the radio resources. Cognitive radio is an …

This paper considers cognitive radio (CR) inspired non-orthogonal multiple-access (NOMA).
Such NOMA users with performance improvement can be achieved as deploying relay …

In this paper, we consider a cooperative autonomous driving system where a vehicle
overtakes the one in front based on collective perception. To avoid collisions with vehicles …

In the current study of cognitive relay networks, most related works focus on the effect of
interference from secondary users (SUs) to primary receivers (PRs), while neglecting the …

We develop robust resource-allocation schemes for a cognitive radio network (CRN), where
the secondary users (SUs) try to communicate with each other from different small cell …

Cognitive radio (CR) systems are potentially capable of mitigating the spectrum shortage of
contemporary wireless systems. In this paper, we provide a brief overview of CR systems …

In this paper, we analyze throughput and delay performance of clustered Machine Type
Communication (MTC) devices which access an eNodeB utilizing a primary spectrum in …

Relay selection is proposed in this paper as an efficient solution to secure information
transmission of secondary users against eavesdroppers in energy harvesting cognitive …

Underlay device-to-device (D2D) communication network is becoming a promising solution
for the fifth generation (5G) and beyond wireless technology. It exploits the proximity of the …

This work is devoted to the error rate analysis of underlay multi‐hop cognitive networks with
arbitrary number of hops in the presence of multipath fading. Novel analytic expressions are …
