Energy efficiency, high data speeds, and effective spectrum utilization stand as the primary
factors governing 5G and beyond networks. A base station (BS) in a cognitive radio network …

In this paper, we identified the optimal number of secondary users in a cooperative spectrum
sensing by maximizing the energy efficiency. We obtain the mathematical expressions and …

The current paper takes into consideration a cognitive radio network with impatient
customers, by the help of finite-source retrial queueing system. We consider two different …

The current paper deals with the simulation of a queuing model developed to evaluate the
performance of a cognitive radio network and its reliability. We take into consideration two …

In this paper, we conduct a research based on the classified secondary users (SUs). SUs
are divided into two categories: higher‐priority SU1 and lower‐priority SU2, and two types of …

This paper deals with a Cognitive Radio Network (CRN) which is modeled using a retrial
queuing system with two finite-sources. This network includes two non-independent service …

The current paper presents a finite-source retrial queuing system that models a Cognitive
Radio Network (CRN) dealing with two types of requests (primary and secondary) attached …

This paper proposes a network tomography scheme for information-centric networking
(ICN), which we call ICN tomography. When content is received over a conventional IP …

In this paper, we consider the transmission needs of communication networks for two
classes of secondary users (SUs), named SU1 and SU2 (lowest priority) in cognitive radio …

In our work, for the purpose of controlling the retransmission behavior of secondary users
(SUs) in cognitive radio networks (CRNs) with hierarchical SUs, we set a feedback …
