Performance Evaluation of IEEE 802.20 PHY Layer

In todaypsilas life, the importance of accessing data and information from Internet and other networks for business, entertainment, and social activity applications is ever increasing. Network protocols such as Wi-Fi (802.11) and WiMAX (802.16) have been developed for such applications. However the need for a high-speed, highly reliable and high quality access to these information services under fully mobile conditions and in vehicular speeds has increased the demand for another network type. IEEE 802.20 standard, nicknamed as Mobile-Fi, has been developed for mobile applications in speeds of up to 250 km/h.In this paper, a complete 802.20 model is introduced that the basic performance of mobile and fixed subscribers is thoroughly evaluated, presenting end-to-end application throughput. The dependency of the application throughput on different modulation schemes for different speeds is analyzed.
