The new compression algorithm based on the Modified Quincunx Wavelets Transform and coupled with the progressive encoder SPIHT (MQWT) is considered one of the algorithms are best suited to reduce the size of the data collected by the Multimedia sensor node. The main objective of this article is to introduce our algorithm (MQWT) to low bitrates in a Wireless Multimedia Sensor Network (WMSN), in order to reduce the complexity of the system, as well as the processing time for the use of the memory. The experimental results show the superiority of the proposed algorithm in terms processing time, the transmission time, the energy consumed during the transmission, the throughput (minimize the transmission delay, and a satisfactory throughput for the bandwidth) and compression performance of the reconstructed image in terms of image quality (PSNR).
