This paper proposes and evaluates a simple energy-aware image transmission protocol suitable for wireless sensor networks. Energy savings is achieved through the use of a wavelet image transform and a semi-reliable transmission. Wavelet image transform provides data decomposition in multiple levels of resolution, so the image can be divided into packets with different priorities. Semi-reliable transmission enables priority-based packet discarding by intermediate nodes according to their battery's state-of-charge. Such approach provides a graceful trade-off between the image quality played out and the sensor nodes' lifetime. An analytical performance evaluation in terms of mean dissipated energy is performed. Results show up to 90% reduction in the energy consumption achieved by our proposal compared to a non energy-aware transmission.
