Low-cost test measurement setup for real IoT BLE sensor device characterization 2019 Access copy available to the general public Unrestricted The methodology presented in this paper aims to characterize impairments shown by real devices which are usually neglected on standardized tests but that become very important in massive IoT scenarios. For instance, we have measured that real BLE scanners are not able to scan continuously even though they are configured to do so. Besides, we have also found and demonstrated that some manufacturers seem not to apply any backoff mechanism although it is mandatory. These two unexpected behaviors have a significant impact on the performance of massive wireless sensor networks based on BLE. So, it becomes necessary to characterize these and other impairments. The proposed tests are based on device current consumption measurements and their association with the information obtained from upper layers. We describe a new low-cost generic measurement setup and provide all the necessary data (configuration parameters, scripts, etc.) for applying the proposed methodology. As an example, we use it to profile the behavior of Bluetooth Low Energy devices. Furthermore, the proposed setup can also inspire researchers to characterize other wireless technology devices, like Wi-Fi, Zigbee, LoRa, etc. info:eu-repo/grantAgreement/ES/DGA/T31-17R info:eu-repo/grantAgreement/ES/MINECO/RTI2018-099880-B-C32 info:eu-repo/grantAgreement/ES/MINECO/TEC2014-58341-C4-2-R info:eu-repo/grantAgreement/ES/MINECO/TEC2014-60258-C2-2-R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 3.364 2019 0.367 2019 ENGINEERING, MULTIDISCIPLINARY 22 / 91 = 0.242 2019 Q1 T1 Applied Mathematics 2019 Q2 INSTRUMENTS & INSTRUMENTATION 13 / 64 = 0.203 2019 Q1 T1 Statistics and Probability 2019 Q2 Education 2019 Q2 Condensed Matter Physics 2019 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-0299-0859 Hernández-Solana, Á.
