Low complexity video coding for sensor networkeSAT Journals
Abstract Modern video codecs such as H.264/AVC give state-of-the-art compression performance. However, extensive use of optimization tools makes them highly complex and hence not suitable for wireless video sensor network. In this paper an efficient video codec with substantially reduced complexity is proposed. Simulation result shows that the proposed video codec gives comparable compression performance compared to H.264/AVC but at substantially reduced computational complexity. Keywords—Low complexity coding, Sensor network, Video coding, Wavelet transform.

This document analyzes delays in unicast video streaming over IEEE 802.11 WLAN networks. It describes conducting an experiment using a testbed with a Darwin Streaming Server and WLAN probe to capture packets. The analysis found that video bitrate variations, packetization scheme, bandwidth load, and frame-based nature of video all impacted mean delay. Bursts of packets from video frames caused per-packet delay to increase in a sawtooth pattern. Increasing uplink load was also found to affect delay variations.
Proxy Cache Management for Fine-Grained Scalable Video StreamingVideoguy
This document proposes a novel video caching framework that uses MPEG-4 Fine-Grained Scalable (FGS) video with post-encoding rate control to achieve low-cost and fine-grained rate adaptation.
