Enhanced IEEE 802.16 Network Performance Utilizing Directional Antennas and Resource Allocation

This paper investigates the performance enhancement of WiMAX (IEEE 802.16) networks through the integration of directional antennas and innovative resource allocation algorithms. Two main methods are presented: a load-balancing technique to guarantee fair traffic distribution among relay stations (RS) and a multi-level search approach for the best communication path selection. When compared to baseline designs, simulations using OPNET software show notable performance gains, such as a 34% increase in throughput and a 26% decrease in delay. These results underscore the potential of the proposed approach in optimizing multi-hop wireless networks, with practical applications in different network scenarios such as WiMAX-based Networks for 5G and IoT.
