A significant problem in data networks is that of congestion control, especially at switching nodes which receive incoming data packets from a number of channels, determine the next destination of these incoming packets, and send them to their destinations. Fair Queuing (FQ) is therefore needed to p.....

An approximated lower-triangle structure for the parity-check matrix of low-density parity-check (LDPC) codes which allows linear-time-encoding complexity of the codes is disclosed, and the parity part of the parity-check matrix is semi-deterministic which allows high flexibility when designing the .....

It introduces new technology to convert color image into grayscale image with high contrast for publishing, printing or medical imaging. In the conventional method, only luminance is used for the conversion of color images to grayscale images. Visual contrasts that are visible in color images become.....

The rapidly emerging mobile data networks fueled by the world-wide deployment of 3G, HSPA, and LTE networks created new challenges for the development of Internet applications. Unlike their wired counterpart, mobile data networks are known to exhibit highly variable bandwidth. Moreover, base station.....

Traditional video-on-demand (VoD) is based on the client-server approach. It is expensive and not scalable. In recent years, the Peer-to-Peer approach was first demonstrated to work for live content streaming, and later for VoD streaming as well. Various efforts are working on building a P2P-base.....
