In Wireless multimedia sensor networks (WMSNs) have an rising variety of multimedia-based applications including image and video transmission. And types of applications, multimedia sensor nodes should ideally maximize perceptual quality and minimize energy expenditures in communication. For the required perceptual quality to be obtained, quality responsive routing is a key research area in WMSNs. On the other hand, mapping the system parameters to the end user’s perceptual measures is a demanding task because of incomplete recognition metrics. Unfortunately, unless disputable assumptions and simplifications are made, optimal routing algorithm is not obedient. In this paper, we propose a novel image transmission structure to optimize both perceptual quality and energy expenditure in WMSNs. A wireless sensor network consists of spatially distributed sensors to monitor physical or environmental conditions, such as temperature, sound, pressure etc. and to kindly pass their data through the network to a major location.
