Multimedia data have become an important objective in
wireless sensor networks. Due to the node resource constraints
(energy consumption, memory capacity, network
latency and throughput) the incorporation of image sensor
at the nodes is currently a challenge.
In this paper, we study different node architectures,
evaluating processing time, energy consumption, image
quality and data delivery issues. The study shows that
a specialized image co-processor is an optimal solutionJUnta de Andalucía P07-TIC-0247
