Multimedia communication in wireless sensor networks is a very challenging task with the critical constraints of these networks. Motion estimation part is the heart of a video compression/coding standard, it can significantly improve video coding efficiency by reducing temporal redundancy existing in a video sequence. It depends on the total number of search points for finding the motion vector in the search window. In this paper, we firstly detail the block matching algorithms
and present our own classification of fast block matching algorithms. Secondly, we introduce our proposal of adopting an adaptive motion estimation algorithm which is more efficient for WMSNs. Finally, we compare between the considered algorithm using in WMSN and our proposal to adopt another algorithm depending on different parameters as Peak Signal to Noise Ratio (PSNR), and compression ratio applied on MATLAB platform. In addition and based on the importance of power consumption over WMSNs, we propose a new method to compare between the different block matching algorithms based on it.
