Abstract:
In an Internet of Things (IoT), a plethora of tiny devices will extend the Internet to the physical world and allow for a completely new class of applications. Two possible IoT scenarios are public safety (e.g., surveillance of areas and borders) and smart cities that offer smart services to improve the lives of a city’s inhabitants. Both share many underlying challenges in terms of realization. They comprise large-scale deployments of sensor nodes and require long-term, battery-driven operation, low-delay reporting of events, as well as secure and attack-resilient design. 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.
