Quality-Oriented Adaptation Scheme (QOAS) for High Bit-rate Multimedia Streaming

Abstract — A Quality Oriented Adaptation Scheme (QOAS) for multimedia streaming in local networks is introduced, and its performance is compared with other existing solutions (TFRCP, LDA+, and non-adaptive). QOAS is designed to balance two opposing goals: providing the highest quality to the end-users, while increasing the network operators ’ revenues by increasing the number of simultaneous customers. Simulation results show that for the same average end-user quality, our QOAS system can accommodate a significantly higher number of simultaneous clients while also having higher bandwidth utilization. For the same number of clients, the average end-user quality is always higher for QOAS than for the other solutions studied
