Onumanyi, A.J. (Adeiza); Abu-Mahfouz, Adnan Mohammed; Hancke, Gerhard P. (Wiley, 2020-04)Some low power wide area network (LPWAN) developers such as Sigfox, Weightless, and Nwave, have recently commenced the integration of cognitive radio (CR) techniques in their respective LPWAN technologies, generally termed ...

Onumanyi, A.J. (Adeiza); Abu-Mahfouz, Adnan Mohammed; Hancke, Gerhard P. (Elsevier, 2021-02)Self-adaptive threshold adjustment algorithms (SATAs) are required to reconfigure their parameters autonomously (i.e. to achieve self-parameter adjustment) at runtime and during online use for effective signal detection ...

Onumanyi, A.J. (Adeiza); Abu-Mahfouz, Adnan Mohammed; Hancke, Gerhard P. (Institute of Electrical and Electronics Engineers, 2020-12)Some recent survey statistics suggest that low power wide area networks (LPWANs) are fast becoming the most prevalent communication platform used in many applications of the Internet of Things (IoT). However, because most ...

Onumanyi, A.J. (Adeiza); Abu-Mahfouz, Adnan Mohammed; Hancke, Gerhard P. (Elsevier, 2018-08)In this paper, we compare local and global adaptive threshold estimation techniques for energy detection in Cognitive Radio (CR). By this comparison, a sum-up synopsis is provided regarding the effective performance range ...

Abdullahi, H.; Onumanyi, A.J. (Adeiza); Zubair, S.; Abu-Mahfouz, Adnan Mohammed; Hancke, Gerhard P. (Springer, 2020-07)The forward consecutive mean excision (FCME) algorithm is one of the most effective adaptive threshold estimation algorithms presently deployed for threshold adaptation in cognitive radio (CR) systems. However, its ...

Oyewobi, Stephen S.; Hancke, Gerhard P.; Abu-Mahfouz, Adnan Mohammed; Onumanyi, A.J. (Adeiza) (Elsevier, 2019-08)Cognitive radio has emerged as an enabling technology in the realization of a spectrum-efficient and delay-sensitive industrial wireless communication where nodes are capable of responding in real-time. However, particularly ...

Oyewobi, Stephen S.; Hancke, Gerhard P.; Abu-Mahfouz, Adnan Mohammed; Onumanyi, A.J. (Adeiza) (MDPI Publishing, 2019-03-21)The overcrowding of the wireless space has triggered a strict competition for scare network resources. Therefore, there is a need for a dynamic spectrum access (DSA) technique that will ensure fair allocation of the ...

Onumanyi, A.J. (Adeiza); Abu-Mahfouz, Adnan Mohammed; Hancke, Gerhard P. (Wiley, 2019-10)Modern energy detectors typically use adaptive threshold estimation algorithms to improve signal detection in cognitive radio–based industrial wireless sensor networks (CR‐IWSNs). However, a number of adaptive threshold ...
