Designing and Implementing a Criticality-Based Duty-Cycled MAC for Low-Latency Mission-Critical Surveillance Applications

Abstract : Image sensor node's activity is defined based on the application's criticality level and sentry nodes with faster capture rates have higher probability to detect intrusions and will alert neighbor nodes. At the MAC level, we consider duty-cycled approaches to periodically set nodes in sleep mode for energy preservation. However, in doing so, care must be taken to also preserve the quality of event detection and sentry nodes must still be able to quickly propagate alert messages to meet the strong requirements of mission-critical surveillance applications in communication delays. We propose an original approach to dynamically determine the duty-cycle length of image sensor nodes to increase the probability of matching active period between nodes, thus reducing the alert latency while globally reducing the energy consumption.
