Voice over Internet Protocol (VoIP) is becoming popular to end-users and sparking great interests in broadband wireless networks. As a mobile version of Worldwide Interoperability for Microwave Access (WiMAX), IEEE 802.16e plays an important role in the evolution towards 4G. In this paper, we have investigated the actual quality of VoIP in the 4G field trial, which aims to better understand the mobile...
This paper considers the transmission performance of multimedia streams, especially Scalable Video Coding (SVC), over mobile WiMAX networks. SVC supports temporal, spatial, and quality scalabilities at bit-stream level, which enables the easy adaptation of video by selecting the sub-sets of bit-stream. Thus, SVC streams are more suitable than non-scalable bit-streams in the mobile environment where...
