Performance Analysis of Addressing Mechanisms in Inter-Operable IoT Device with Low-Power Wake-Up Radio.

ABSTRACT: Internet of Things (IoT) technology is rapidly expanding the use of its application, from individuals to industries. Owing to this, the number of IoT devices has been exponentially increasing. Considering the massive number of the devices, overall energy consumption is becoming more serious. From this point of view, attaching low-power wake-up radio (WUR) to the devices can be one of the candidate solutions to deal with this problem. With WUR, IoT devices can go to sleep until WUR receives a wake-up signal, which enables a significant reduction of its power consumption. Meanwhile, one concern for WUR operation is the addressing mechanism, since operational efficiency of the wake-up feature can significantly vary depending on the addressing mechanism. We therefore introduce addressing mechanisms for IoT devices equipped with WUR and analyze their performances, such as elapsed time to wake up, false positive probability and power/energy consumption, to provide appropriate addressing mechanisms over practical environments for IoT devices with WUR.

Project description:BackgroundAbout one in five strokes occur during sleep (wake-up stroke). People with wake-up strokes have traditionally been considered ineligible for thrombolytic treatment because the time of stroke onset is unknown. However, some studies suggest that these people may benefit from recanalisation therapies.ObjectivesTo assess the effects of intravenous thrombolysis and other recanalisation therapies versus control in people with acute ischaemic stroke presenting on awakening.Search methodsWe searched the Cochrane Stroke Group Trials Register (last search: 9 January 2018). In addition, we searched the following electronic databases in December 2017: Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 11) in the Cochrane Library, MEDLINE, Embase, US National Institutes of Health Ongoing Trials Register ClinicalTrials.gov, World Health Organization International Clinical Trials Registry Platform (WHO ICTRP), the ISRCTN registry, and Stroke Trials Registry. We also screened references lists of relevant trials, contacted trialists, undertook forward tracking of relevant references, and contacted manufacturers of relevant devices and equipment.Selection criteriaRandomised controlled trials of intravenous thrombolytic drugs or intra-arterial therapies in people with acute ischaemic stroke presenting upon awakening.Data collection and analysisTwo review authors applied the inclusion criteria, extracted data, and assessed trial quality and risk of bias using the GRADE approach. We obtained both published and unpublished data.Main resultsWe included one pilot trial with nine participants. The trial was a feasibility trial that included participants with an unknown onset of stroke and signs on perfusion computed tomography of ischaemic tissue at risk of infarction, who were randomised to alteplase (0.9 mg/kg) or placebo. One trial was prematurely terminated due to signs of efficacy of the intervention arm; we did not include this trial because we were not able to obtain data for the portion of the participants with wake-up stroke after requesting this information from the trial authors. We identified six ongoing trials.Authors' conclusionsThere is insufficient evidence from randomised controlled trials for recommendations concerning recanalisation therapies for wake-up stroke. Results from ongoing trials will hopefully establish the efficacy and safety of such therapies.
