Abstract--Extensive efforts have been focused on deploying
broadband wireless networks. Providing mobile users with high
speed network connectivity will let them run various multimedia
applications on their wireless devices. Satisfying users with dif-
ferent quality-of-service requirements while optimizing resource
allocation is a challenging problem. In this paper, we discuss
the challenges and possible solutions for transmitting MPEG
video streams over WiMAX networks. We will briefly describe
the MPEG traffic model suggested by the WiMAX Forum. A
cross-layer solution for enhancing the performance of WiMAX
networks with respect to MPEG video streaming applications is
explained. Our solution uses the characteristics of MPEG traffic
to give priority to the more important frames and protect them
against dropping. Besides, it is simple and compatible with the
IEEE 802.16 standards and thus easily deployable. It is shown
