Abstract: WIMAX (IEEE802.16) is an alternative solution to traditional wired broadband techniques due to its cost efficiency. Being an emerging technology, WiMAX supports multimedia applications such as voice over IP (VoIP) and video conference. It is necessary to provide Quality of Service (QoS) guaranteed with different characteristics for Broadband Wireless Access (BWA) networks. Therefore, an effective scheduling is critical for the WiMAX system. Many traffic scheduling algorithms are available for wireless networks, e.g. strict priority, Weighted Round Robin and Round Robin scheme. This paper uses an effective video transmission using H.264video codec over Wimax networks using fuzzy based scheduling algorithm. To support various services by considering the QoS constraint with respect to BER, PSNR, Throughput, delay of rtps class. H.264 video compression and decompression is used to provide high quality video at low bit rate without increasing the complexity of the design The proposed scheme provides better QoS support for each class efficiently for WiMAX using MATLAB simulation.
