Due to the under-utilization problem of the allocated radio spectrum, cognitive radio (CR)
communications have recently emerged as a reliable and effective solution. Among various …

It is widely believed that the advances of networking technologies will reshape the future of
telecommunication system. The continuous growth in data traffic originated by mobile users …

In this paper, the hybrid spectrum access and prediction techniques are exploited
simultaneously in the high-traffic cognitive radio communication system, in order to enhance …

The spectrum mobility during data transmission is an integral part of the cognitive radio
network (CRN) which is conventionally two types for instance reactive and proactive. In the …

Because of numerous dormant application fields, wireless sensor networks (WSNs) have
emerged as an important and novel area in radio and mobile computing research. These …

In this paper, a hop-by-hop relay selection strategy for multi-hop underlay cognitive relay
networks (CRNs) is proposed. In each stage, relays that successfully decode the message …

The internet of everything (IoEs) has become a well-known tool for transforming the concept
of connected environments into reality in near future. The cognitive radio network is a …

In this paper, we study the performance of wireless-powered cluster-based multi-hop
cognitive relay networks (MCRNs), where secondary nodes harvest energy from multiple …

This paper introduces the concept of imperfect spectrum monitoring for realistic wireless
communication environments with high-traffic cognitive radio networks (HTCRN). The effect …

The spectrum‐monitoring is a prominent technique to detect the reappearance of the
primary user (PU) during the cognitive users'(CUs) data transmission. However, the …
