In this paper, a method to connect QoE directly to QoS according to the corresponding level of QoE under different network circumstance is proposed. The algorithm used to analysis a number of data is the BP (back-propagation) neural network toolbox in Matlab software. With the help of video quality evaluation system and network emulator, all kinds of parameters of different network circumstance and...
This paper presents an algorithm to mend the Enhanced Adaptive FEC (EAFEC) mechanism for improving video delivery over WLAN. The algorithm is based on two factors, first of which is the queue length in the access point (AP), indicating network traffic load; the other is packet retransmission times, indicating wireless channel state. According to these factors, two different redundant FEC packets were...
