Published in 2017 at "Wireless Networks"

DOI: 10.1007/s11276-015-1152-4

Abstract: Auction is often applied in cognitive radio networks due to its efficiency and fairness properties. An important issue in designing an auction mechanism is how to utilize the limited spectrum resource in an efficient manner.… read more here.

Published in 2017 at "Wireless Networks"

DOI: 10.1007/s11276-016-1212-4

Abstract: Due to the mobility of node and different spectrum availability pattern, CR networks are frequently divided into unpredictable partitions. Usually, these partitions are irregularly connected; hence, secure and reliable routing becomes major issue for these… read more here.

Published in 2018 at "Wireless Networks"

DOI: 10.1007/s11276-017-1489-y

Abstract: AbstractEstablishing communications in a cognitive radio networks (CRNs) requires communicating nodes to “rendezvous” before transmitting their data packets. Channel hopping (CH) rendezvous algorithms can provide guaranteed rendezvous for CRNs without common control channels. A new… read more here.

Published in 2018 at "Wireless Personal Communications"

DOI: 10.1007/s11277-018-5871-6

Abstract: Cognitive radio networks (CRNs) have a shortcoming in that attackers can increase their ability to disturb secondary users (SUs). This paper focuses on jamming attacks in the physical layer, in which several attackers try to… read more here.

Published in 2020 at "Wireless Personal Communications"

DOI: 10.1007/s11277-020-07027-5

Abstract: In this paper, we derive the packet error probability of cognitive radio networks. Our analysis is valid when the powers of secondary source and relays are adaptive. The secondary source and relays can adapt their… read more here.

Published in 2021 at "Wireless Personal Communications"

DOI: 10.1007/s11277-021-08987-y

Abstract: In this paper, we suggest to optimize both power allocation coefficients, harvesting and sensing durations for cognitive radio networks using non orthogonal multiple access (CR-NOMA). In the first slot, secondary transmitter harvests energy from radio… read more here.

Published in 2018 at "Optimization Letters"

DOI: 10.1007/s11590-017-1119-8

Abstract: In usual cognitive radio networks with buffer settings, secondary user packets that are interrupted by primary user packets will return to the SU buffer for later retransmission. But this may increase the average delay of… read more here.
