Discrete Wavelet Transform (DWT) was developed to improve the performance of data compression. Hybrid Fast Zonal-DCT with DWT is proposed to enhance the image compression during the transmission in WSN. The reduction in power consumption relies on data distribution in the clusters. The performance of the proposed algorithm is monitored by some metrics. The enhancement in image quality and compression ratio is achieved.
