Wireless Sensor Network (WSN) is composed of tiny sensors and they are powered by energy-constraint battery. The continual need to utilize limited bandwidth to absorb most of the packets has led to a great deal of research in the field of data compression. WSN has been exploited to balance the maintenance of readable information content with acceptable error and the cost of energy consumed by the collecting nodes during the compression. In this paper, the authors compared two compression techniques: JPEGand watermark authentication.
