Abstract In Cognitive radio-based Internet of Things (CR-IoT) systems, the return of the
primary user (PU) causes the secondary user (SU) that is communicating to face the …

In this work, we proposed a new artificial bee colony–based spectrum handoff algorithm for
wireless cognitive radio systems. In our wireless cognitive radio system, primary users …

Cognitive radio (CR) is projected as a technology (or solution) that will raise the spectrum
utilization considerably by allowing low-priority or secondary user (SU) to utilize the …

In cognitive radio network, spectrum handoff occurs when primary user appears in the
licensed band which is occupied by the cognitive user. Spectrum handoff aims to help …

The CRN is an intelligent network in identifying the empty space from the spectrum without
causing any interference to the primary user (PU). Due to the stable allocation of the …

Spectrum handoff is a crucial function of Cognitive Radio (CR) which is the change of
operating frequency. The main problem in spectrum handoff is the time taken in the …

In this paper, we present an analytical framework to evaluate the latency performance of
connection-based spectrum handoffs in cognitive radio (CR) networks. During the …

Spectrum handoff is one of the key techniques in a cognitive radio system. In order to
improve the agility and the reliability of spectrum handoffs as well as the system throughput …

The secondary usage of spectrum has been investigated in Cognitive Radio (CR) network to
resolving the spectrum scarcity issue in wireless communication. When Primary Users (PU) …

Wireless communication technology is the future of communication, but rapid growth in
wireless technology has led to a scarcity in the spectrum. Thus, the world has moved away …
