CUPID: A Communication Pattern Informed Duty Cycling for Large-Scale, Low-Delay Sensor Applications
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. The authors 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 tradeoffs between these two conflicting goals are hard to find.
