In this study, priority based non-preemptive M/G/1 queueing model of spectrum handoff
scheme is proposed in Wireless Cognitive Radio Networks. Channel bonding mechanism …

In this study, a non‐preemptive M/G/1 queueing model of a spectrum handoff scheme for
cognitive wireless networks is proposed. Because spectrum handoff gives secondary users …

Spectrum handoff has a negative impact on the performance of cognitive users (CUs) in
terms ofhandoff delay in cognitive radio (CR) networks. In this study, a pre‐emptiveresume …

Spectrum handoff is an inevitable phenomenon to exploit dynamic spectrum access in
cognitive radio networks (CRNs) for better spectrum utilisation. When a licensed or primary …

In this paper, we derive upper bound of Packet Error Probability (PEP), upper bound of delay
and lower bound of throughput in cognitive radio networks. Our analysis is valid when the …

Cognitive radio has emerged as a new technology that provides usage of unused or under-
utilized portions of frequency bands in an effective manner. Wireless cognitive radio …

The cognitive radio network permits secondary users to reach unused spectrum of primary
users. In this paper, a mixed preemptive/non-preemptive resume priority M/G/1 queuing …

Spectrum handoff is a process performed by secondary users in cognitive radio networks. To
accomplish this, the base station that coordinates the secondary users decides which user …

This paper analyses opportunistic access of secondary user in cognitive radio network
(CRN) using analytical M/D/1 queuing model. Through using spectrum sharing, secondary …

In this paper, we consider a cognitive radio networks with secondary users that can choose
either to access the idle licensed channel with overlay mode or access the busy licensed …
