In video surveillance with resource-constrained devices such as wireless video sensor nodes, power conservation, intrusion detection, and security are important features to guarantee. In this paper, we intend to preserve the network lifetime while fulfilling the surveillance application needs. We take into account security by considering that a malicious attacker can try to predict the behavior of the network prior to intrusion. These considerations lead to the definition of a novel chaos-based scheduling scheme for video surveillance. We explain why the chaos-based approach can defeat malicious intruders. Then, by simulations, we also compare our chaos-based scheduling to a classical random scheduling. Results show that in addition of being able to increase the whole network lifetime and to present comparable results against random attacks (low stealth time), our scheme is also able to withstand malicious attacks due to its fully unpredictable behavior.
