Multimedia Streaming in WiMAX Networks

This project studies multimedia services in the emerging WiMAX networks. We look into efficient multimedia broadcast framework over mobile WiMAX networks utilizing the MBS and sleep mode features, in particular, broadcasting multiple scalable video streams to mobile receivers. We study problems like maximizing the quality of video at mobile receivers, minimizing energy consumption at mobile receivers and other related problems.
