摘要: In this study we set up an ad-hoc testbed of heterogeneous devices and investigate the behavior video audio streaming over TCP protocol. The metrics for measuring quality service (QoS) flows, are round trip time (RTT) signal to noise ratio (SNR). Our findings indicate inverse correlation between RTT SNR, with first value increasing exponentially after a lower SNR threshold. Device movement large distances two factors affecting negatively. Finally show that impact background traffic on these applications is prominent, as it increases significantly
