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
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
Quality of service aware channel allocation for white spaces radio networks

Author: Masonta, Moshe T ; Rananga, S Date: Aug 2023 The growing demand for high-speed and ubiquitous connectivity continues to present new challenges for efficient usage, management and sharing of radio frequency spectrum. Dynamic spectrum access concept, enabled by cognitive radio technology, ... Read more
A road map for wireless mesh routing with DSA

Author: Maliwatu, R ; Zlobinsky, Natasha ; Densmore, M ; Johnson, D Date: Sep 2016 Dynamic Spectrum Access (DSA) provides a new opportunity for last-mile and rural connectivity. However, the nature of DSA and varying environmental conditions means that desired spectrum is not always available. To that end, we have deployed ... 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
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
