Adaptive spectrum decision framework for heterogeneous dynamic spectrum access networks

Author: Masonta, Moshe T ; Mekuria, Fisseha ; Mzyece, M ; Djouani, K Date: Sep 2015 Spectrum decision is the ability of a cognitive radio (CR) system to select the best available spectrum band to satisfy dynamic spectrum access network (DSAN) users¿ quality of service (QoS) requirements without causing harmful interference ...

Cognitive radio in low power wide area network for IoT applications: Recent approaches, benefits and challenges

Author: Onumanyi, Adeiza J ; Abu-Mahfouz, Adnan MI ; Hancke, GP Date: Nov 2019 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 LPWANs are generally ... Read more c b
A comparative study of cognitive radio platforms

Author: Masonta, Moshe T ; Mzyece, M ; Mekuria, Fisseha Date: Oct 2012 Cognitive radio (CR) technology has become one of the buzzwords within the wireless communications community over the past 12 years. Its ability to learn, decide and adapt to the external environment made CR attractive to regulators, researchers, ... Read more
A cuckoo search optimization-based forward consecutive mean excision model for threshold adaptation in cognitive radio

Author: Abdullahi, A ; Onumanyi, Adeiza J ; Zubair, S ; Abu-Mahfouz, Adnan MI ; Hancke, GP Date: Nov 2019 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 effectiveness is often ... Read more
Exploring control-message quenching in SDN-based management of 6LowPANs

Author: Ndiaye, M ; Abu-Mahfouz, Adnan MI ; Hancke, GP ; Silva, B Date: Jul 2019 This paper draws attention to techniques available for the minimization of control overhead in software-defined wireless sensor networks (SDWSNs). Software-defined networking (SDN) promises improved management flexibility and control for ... Read more
Practical implementation of geo-location TVWS database for Ethiopia

Author: Hussien, HM ; Katzis, K ; Mfupe, Luzango P ; Bekele, ET Date: Aug 2019 The opening of Television White Spaces for cognitive access is one of the first tangible steps towards solving the spectrum scarcity as well as rural connectivity problems. Because this part of the spectrum band offers better bandwidth, good ... Read more
Towards Cognitive Radio in Low Power Wide Area Network for Industrial IoT Applications

Author: Onumanyi, Adeiza J ; Abu-Mahfouz, Adnan MI ; Hancke, GP Date: Jul 2019 In this paper, we have discussed the integration of Cognitive Radio (CR) in Low Power Wide Area Network (LPWAN) based on a generic network architecture and a PHY layer front-end model. Essentially, since most existing LPWAN technologies are ... Read more
