\'Evaluation d'une application de transmission d'images m\'edicales avec   un r\'eseau sans fil
  We offer a platform for database consultations and/or biomedical images exchanges, adapted to the low rate wireless transmission, and intended for general practitioners or specialists. The goal can be preventive, diagnostic and therapeutic. it Concerns specialties such as radiology, ultrasound, the anatomical pathology or endoscopy. The main features required in such a context are to adjust the data compression of both the specific needs of telemedicine and limited capabilities of wireless communication networks. We present our approach in which we have set out criteria on Biomedical images quality, compressed by the wavelet method to retain all the necessary information for an accurate diagnosis, and determined the characteristics of a wireless network with minimal performances for the transmission of these images within constraints related to the modality and the data flow, in this case Wifi based on the IEEE 802.11 standard. Our results will assess the capacity of this standard in terms of speed, to transmit images at a rate of 10 frames per second. It will be necessary to quantify the amount of information to add to the image datas to enable a transmission in good conditions and the appropriate modus operandi.
