Box, 7, 61710, Mutah, Al-Karak, Jordan aut A New WiMAX/Wi-Fi Interoperability Model and Its Performance Evaluation [Elektronische Daten] [Aymen Zreikat] In this paper, a new interoperability model for deployment of the emerging IEEE 802.16; WiMAX (World Wide Interoperability for Microwave Access) and a Wi-Fi (Wireless Fidelity), IEEE 802.11 based on Wireless LAN technology in a complementary way as a path to migration towards the upcoming fourth generation, is presented. The model allows for the integration of the two technologies, combining the benefits of both worlds for Non line-of-sight environments. The suggested scenario is to have a hotspot Wi-Fi or urban cell surrounded by a set of WiMAX (suburban) cells where users can have continuous connectivity in different propagation environments. If the C/I (Carrier-to-Interference) of a user is higher than a given threshold (say C/I $$>$$ G) then the user connects to the Wi-Fi cell otherwise the user is admitted to a WiMAX cell. In both cases, the user will have the best of the available access technology with an acceptable level of grade-of-service, i.e. $$<$$ 2%, on move. The suggested model includes mixed services support i.e. voice, data and video with mobility, as well as scalability based on scalable orthogonal frequency division multiplexing adaptive bandwidth allocation. The scalability is applied on data connection, where ongoing data connection is asked to modify its transmission rate for the sake of handover calls. Numerical results from the evaluation of the interoperability model are given. The curves for average data rate, utilization, blocking probability, handover blocking probability, grade of service, and throughput demonstrate the effectiveness of the new deployment model.
