NITOS Energy Monitoring Framework: Real time Power Monitoring in Experimental Wireless Network Deployments

Development of energy-ecient protocols and algorithms re-quires in-depth understanding of the power consumption characteristics of real world devices. To this aim, energy eciency analysis is performed by the research community, mainly focusing on the development of power consumption models. However, recent studies [1] have highlighted the inability of existing models to accurately estimate energy consumption even in non-composite scenarios, where the operation of a single device is analyzed. The inability of such models is further highlighted under real life scenar-ios, where the impact induced by the simultaneous opera-tion of several devices renders the application of traditional models completely inappropriate. As a result, energy e-ciency evaluation under complex configurations and topolo-gies, needs to be experimentally investigated through the application of online monitoring solutions. In this work, we propose the innovative NITOS Energy consumption Moni-toring Framework (EMF) able to support online monitoring of energy expenditure, along with the experiment execution. The developed framework is built on a distributed network of low-cost, but highly accurate devices and is fully inte-grated with the large-scale wireless NITOS testbed. The framework evaluation is performed under both low-level ex-periments that demonstrate the platform’s high-level accu-racy, as well as through high-level experiments that showcase how online and distributed monitoring can facilitate energy performance assessment of realistic testbed experiments. 1
