Color Image Compression (Lossy) Through Selective Component Technique and Block Truncation Compression Technique
Abstract: This is a lossy image compression technique, where image is compressed by combination of two individual lossy compression techniques. The first technique is the selective component technique, where any one of the 3 components (R, G, B) is taken in a particular order preserving the colour information of the pixels in lossy manner; and the second technique is the block truncation technique (BTC) applied to the output of the previous …

TCP Performance Analysis by Loss Differentiation Algorithm over Lossy Wireless Links
Abstract: TCP continues to be an important transport-layer communication protocol that is typically tuned to perform well in traditional wired networks, where bit error rate is low and congestion is the primary cause of packet loss. Wireless networks are prone to High BER, which is responsible for large number of packet losses. TCP incorrectly interprets these losses as signs of network congestion and throttles its transmission rate unnecessarily, which degrades end-to-end …
