As the main goal of network media service transmission, to meet and enhance the quality of experience (QoE) for users, and optimize transmission control mechanism. High-definition (HD) streaming media technology demands larger bandwidth. While QoE evaluation needs to consider multiple paths network transmission quality of service (QoS), path payload distribution, service features and other attributes...
This paper studies some issues to implement multi-agency in Mobile video grid, the load balance among the mobile agents used by one mobile synchronously; the discovery of multiple agents for one service and the requirement for network topology. After analyze in theory, a series of simulation experiments in NS-2 are carried out to verify the theoretic conclusions. The results show it can benefit by...
In this paper, we propose a systematic design of full-diversity space-frequency (SF) codes for multiuser MIMO-OFDM systems. With joint maximum likelihood detection, the proposed codes can obtain full diversity over selective-fading multiple access channels. The proposed coding scheme does not require the cooperation of multiple transmitters, nor the instantaneous channel side information at the transmitters...
IP multicast has been proposed for over a decade, but deployment in heterogeneous Internet is still limited within small area for lack of network management and congestion control. Many application layer multicast (ALM) protocols have been proved to be more scalable and feasible than IP multicast in practical environment. In this paper, we propose an ALM protocol called scalable hierarchical multicast...
Streaming media services have been developing prosperously across cable network in recent years. Though wireless network becomes more and more popular in our lives, most of the technologies using in cable network are not suitable for wireless because of the differences between the physical layers of the two. In this survey, we summarized the wireless streaming media technologies studied in recent...
