Abstract :
Video transmission over wireless sensor networks (WSN) is a very challenging research field. With sensor nodes operate on limited energy resource, computational power and network bandwidth, energy efficient coding and transmission are of extreme important. As opposed to normal video system, video sensor network (VSN) system needs to provide high quality information only when situation calls for it. However, a certain degree of quality has to be guaranteed, especially for the region of interest (ROI) part. In this paper, a simple technique based on multiple description coding (MDC) to reduce the amount of information transmitted while maintaining a higher quality standard for the ROI part of the frame is proposed. Experimental results show some significant gain in energy conservation as compared to the existing techniques.
