Implementation of an Age of Information-aware Scheduler for Resource Constrained Devices

Sammanfattning: We examine a system where remote applications frequently request fresh information from sensor nodes through an edge and cloud based infrastructure. We study a scheduling policy that ensures fresh information while reducing energy consumption. In this work we build a testbed for evaluating the performance of the policy. We present a solution to synchronizing devices over a wireless network. We discuss the challenges of using resource constrained devices in an environment where power is limited. We run experiments to evaluate the timing of the testbed and to see how the scheduling policy performs compared to the typical periodic schedule. Our results when testing the schedule are inline with the findings in the theoretical literature. We find that good timing of the testbed requires extensive communication for adjusting the timers.
