We design predictors of user dissatisfaction with the performance of applications that use
networking. Our approach combines user-level feedback with low level machine and …

Latency-sensitive applications (eg, wireless gaming and TV remote play) are increasingly
popular in home WiFi networks. Such millisecond-level latency requirements call for new …

Rate adaptation (RA) has been traditionally used to achieve high goodput. In this work, we
design RA for 802.11 n NICs from an energy-efficiency perspective. We show that current …

Virtual reality (VR) applications are increasingly popular. With high-quality video streams
and interactive content, they require both low-latency and high-bandwidth performance …

Wireless LANs (WLANs) carry a diversemix of traffic, ranging from delay-sensitive real-time
applications to bulk transfers. Using existing QoS mechanisms in high speed WLANs (eg …

In this paper, we study the effects of frame aggregation on video streaming performance in a
real-world IEEE 802.11 n testbed. We quantitatively characterize delay, video quality, and …

In this paper, we propose rate adaptation mechanisms for robust and low-latency video
transmissions exploiting multiple access points (Multi-AP) wireless local area networks …

We propose a joint source channel coding framework for real time transmission of H.
264/AVC single layer video signals over wireless MIMO channels. In the proposed …

We present a framework for cross‐layer optimized real time multiuser encoding of video
using a single layer H. 264/AVC and transmission over MIMO wireless channels. In the …

Wireless LANs (WLANs), based on the IEEE 802.11 standard, have become the standard
means for indoor wireless connectivity. At the same time, the rising number of smart mobile …
