Abstract

Unlike Wi-Fi, BWA (Broadband wireless access) technology provides high-speed communication in a wide area. The IEEE 802.16d (WiMAX) standard of wireless mesh net-works is one of the widely used BWA standard. WiMAX mesh mode achieves data transmission in conflictfree manner in multihop networks by using the control messages (three way hand-shake messages or MSH-DSCH messages) to reserve channel for sending data. Concurrently, coordination of three way handshake messages depends on the mechanism named Election based Transmission Timing (EBTT). However, IEEE 802.16d mesh mode uses a static holdff algorithm, which leads to a low performance in the majority of cases. In this paper, after analyzing the IEEE 802.16d mesh mode with coordinated distributed scheduling, we propose a novel method to improve the throughput by a dynamic holdoff algorithm. The simulation results show that our proposal gets a better throughput performance.
