We consider a situation where a video sequence is to be compressed and transmitted over a
wireless channel. Our goal is to limit the amount of distortion in the received video …

Rapid growth in wireless networks is fueling demand for video services from mobile users.
While the problem of transmitting video over unreliable channels has received some …

In this work, we introduce an approach for minimizing the total power consumption of a
mobile transmitter due to source compression, channel coding and transmission subject to a …

Mobile devices performing video coding and streaming over wireless and pervasive
communication networks are limited in energy supply. To prolong the operational lifetime of …

Video communication over wireless links using handheld devices is a challenging task due
to the time-varying characteristics of the wireless channels and limited battery resources …

Real-time encoding and error-resilient wireless transmission of multimedia content using
traditional encoding techniques requires relatively high processing and transmission power …

Advances in wireless multimedia communication technologies enable new types of
pervasive and ubiquitous applications such as mobile health care, environmental …

We describe a method to maintain quality for video transported over wireless channels. The
method is built on three fundamental blocks. First, we use a transcoder that injects spatial …

Energy minimization is an important design goal in wireless video transmission. We
examine how the RF energy and the analog circuit energy, which account for a large part of …

In cyber-physical systems where sensors measure the temporal evolution of a given
phenomenon of interest and radio communication takes place over short distances, the …
