New applications of wireless sensor networks require vision capabilities. Considering the high loss rates found in sensor networks, and the limited hardware resources of current sensor nodes, low-complexity robust image transmission must be implemented, avoiding as much as possible the need for retransmission or redundancy. In this paper we propose a pixel interleaving scheme based in Torus Automorphisms, thus, neighboring pixels are transmitted in different packets. Hence, if packets are lost, we have a high probability of retrieving enough information to obtain an approximation of the original value. Results show an increase of the image quality in comparison with a sequential raw image transmission approach, while preserving similar energy consumptions, time and low-complexity.
