Location Based QoS Estimation of OFDM-WIMAX Network

Wimax, a next generation high-speed wireless access network provides larger coverage along with sting QoS and security mechanism compared to WiFi. In this paper, we have demonstrated QoS estimation of location based OFDM-Wimax access network and is followed by a comparison of performance of the reported OFDM-Wimax network at each location. The obtained simulative results prop up the influence of the position of MS home agent over performance of proposed Wimax network significantly. Further, the performance improvement due to incorporation of OFDM technology by reducing the fading problem in such wireless networks is reported. The proposed OFDM-Wimax access network achieved a prolonged coverage area with acceptable uplink and downlink SNR together with required BLER than that of conventional Wimax networks. The performance of proposed OFDM-Wimax network is evaluated with respect to QoS parameters such as throughput, average delay (Uplink/Downlink), end to end delay (Uplink/Downlink), packet jittering (Uplink/Downlink), SNR (Uplink/Downlink), BLER (Uplink/Downlink), and packet dropped (Uplink/Downlink).
