Now that sensor networks are gradually deployed in commercial settings, they must live up to many expectations, particularly offering both years of unattended operation and low-delay event reporting. However, experiences from real-world trials have shown that decent trade-offs between these two conflicting goals are hard to find. In this paper, we show how staggered wake-ups achieve this. We call this low-delay and low-power duty cycle management scheme CUPID because its parameterization is based on the expected communication patterns in the network, duty-cycle and latency requirements. We show by simulations and real-world experiments with more than 150 nodes that our scheme significantly reduces the packet delay for low-duty cycle settings, especially in large networks.
