Abstract
The most challenging issue in worldwide interoperability for microwave access network technologies is to find a way to counteract the interference as well as solve the fading problems in transmission. Although IEEE 802.16e standard is proposed to tackle this difficult problem, there are still many external interferences, which may corrupt ongoing transmissions. To diminish this effect, this paper proposes a fault-tolerant transmission mechanism (FTM) by adjusting the burst size, rearranging slot allocation, and comparing patterns to provide a reliable, secure, and quality transmission. Simulation results reveal that in an efficient transmission, the burst size has to be considered no more than 20 slots; it should not exceed 5% of the total frame space. Furthermore, FTM yields approximately 30% throughput and significantly raises the successful transmission probability compared to IEEE 802.16e transmission mechanism, while still being fully compatible with all frame-based WiMAX system.
