Analysis of propagation model performance in WiMAX (IEEE 802.16e)-based wireless mobile vehicular networks

WiMAX is an appropriate wireless technology for networked vehicular applications in intelligent transportation system because of its mobility support at vehicular speeds and its inherent wide coverage. In this paper, performance of a WiMAX (IEEE 802.16e Standard) mobile vehicular network is investigated under different existing empirical propagation models, hand-off scenarios and variation of speed for a moving MS. The study leads to the selection of a suitable propagation model for better performance with higher throughput and lower path loss. The network simulation is done by NCTUns simulation tool with design paradigms specified for WiMAX (IEEE 802.16e).
