Comparison of metaheuristic algorithms for interface-constrained channel assignment in a hybrid Dynamic Spectrum Access – Wi-Fi infrastructure WMN

Author: Zlobinsky, N ; Johnson, DL ; Mishra, AK ; Lysko, Albert A Date: Feb 2022 In this work, we evaluate the application of four different metaheuristic optimisation algorithms for solving the channel assignment problem in a multi-radio multi-channel Wireless Mesh Network (WMN) using Dynamic Spectrum Access (DSA). The ... Read more
Dynamic Spectrum Access: regulations, standards and green radio policy considerations

Author: Mfupe, Luzango P ; Masonta, Moshe T ; Olwal, T ; Mzyece, M Date: Sep 2012 Dynamic spectrum access (DSA) technologies are increasingly viewed as a potential solution to improve overall spectral utilisation efficiency and for bridging the digital divide in the rural areas. In particular, DSA technologies have the ... Read more
Metaheuristic optimisation for radio interface-constrained channel assignment in a hybrid Wi-Fi–Dynamic Spectrum Access wireless mesh network

Author: Zlobinsky, N ; Johnson, D ; Mishra, AK ; Lysko, Albert A Date: Dec 2021 Channel Assignment (CA) in wireless mesh networks (WMNs) has not been well studied in scenarios where the network uses Dynamic Spectrum Access (DSA). This work aims to fill some of this gap. We compare metaheuristic algorithms for optimising ... Read more
Simulation and channel assignment by Simulated Annealing of a wireless mesh network using Dynamic Spectrum Access

Author: Zlobinsky, N ; Mishra, AK ; Johnson, DL ; Lysko, Albert A Date: Nov 2021 This work tackles a new angle to the Channel Assignment (CA) problem, which has otherwise been fairly widely studied for allocating channels optimally to access points and ad-hoc network nodes. Wireless Mesh Networks (WMNs) using Dynamic ... Read more
Spectrum database as a service (SDaaS) for broadband innovation and efficient spectrum utilization

Author: Mfupe, Luzango P ; Montsi, L ; Mekuria, Fisseha Date: Oct 2013 Broadband innovations for future wireless networks involves rapid sharing of radio frequency (RF) spectrum resources by means of dynamic spectrum access techniques (DSA) to satisfy immediate portfolio of heterogeneous demands of wireless IP ...

Towards dynamic spectrum access and 5G, via television white spaces

Author: Lysko, Albert A Date: May 2017 The world has just began taking advantage of the fourth generation (4G) communication technologies, whilst both research and industry communities are already starting with debates around 5G. Besides the antenna based and multiple-input ... Read more
TVWS devices spectrum mask test and analysis

Author: Lamola, MM ; Johnson, David ; Lysko, Albert A ; Zlobisnky, Natasha Date: Sep 2016 Dynamic Spectrum Access (DSA) plays a vital role in opportunistic access to spectrum. A key component of DSA is preventing interference to the incumbent (primary) user from the secondary user. We present the results of an experiment to analyze ... Read more
