Fine-grained channel access in wireless LAN
Modern communication technologies are steadily advancing the physical layer (PHY) data rate in wireless LANs, from hundreds of Mbps in current 802.11n to over Gbps in the near fut...

Stochastic frame buffers for rate distortion optimized loss resilient video communications
In this paper we propose an error control scheme for video communications over lossy channels. The proposed algorithm uses stochastic frame buffers(SFB) to determine the expected ...

Embedded multiple description coding for progressive image transmission over unreliable channels
A multiple description scalar quantization (MDSQ) based coding system can be regarded as a source coder (quantizer) followed by a channel coder, i.e. the combination of index and ...

Rateless coding for hybrid free-space optical and radio-frequency communication
Abstract--Free-space optical (FSO) transmission systems enable high-speed communication with relatively small deployment costs. However, FSO suffers a critical disadvantage, namely...

An On-Off Queue Control Mechanism for Scalable Video Streaming over the IEEE 802.11e WLAN
— In this paper, we study the issue of scalable video streaming over IEEE 802.11e EDCA WLANs. Our basic idea is to control the number of “active” nodes on the channel in orde...
