Radio Resource Management of WLAN Hotspot Access Points in Next Generation Wireless Networks

The proliferation of the IEEE wireless local area network (WLAN), due to its flexibility, mobility, and support for billions of smart mobile devices, has gained widespread popularity. The high data rate, low complexity, and low cost make the IEEE WLAN suitable for deploying next generation wireless networks. The WLAN developed to carry packet data is currently deployed to transport packetized voice. However, integrating packet data and packetized voice poses new design complexity. This paper proposes an improved resource allocation management protocol to boost the performance of the infrastructure WLAN by enhancing its quality of service (QoS) parameters. Analytical expressions were derived for the point coordination function (PCF) infrastructure WLAN and simulated in MATLAB. Simulation results show an exponential decrease in throughput and spectral efficiency with increased randomized packets in the workstations investigated. Overall, results indicate that the queue delay and cycle duration of the PCF WLAN access increase exponentially with an increase in traffic density. The projected resource allocation management protocol would pose practical applications in improving the performance of the infrastructure WLAN in next generation wireless networks. © 2023, The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd.
