Fast Abstracts are short two-page papers that are selected to highlight promising avenues of research in the area of dependability. The first paper is a cautionary tale in trusting heart rate measurements from our smartwatches and explores the root cause behind the unreliability. The second paper shows how a mobile device can choose an edge computing node for offloading computation &#8212; importantly, it provides the first simulator that people can use to develop their solutions in this space.<\/li><\/ol>\n\n\n[A] <a class=\"text-bold ng-binding\" href=\"https:\/\/engineering.purdue.edu\/dcsl\/publications\/papers\/2020\/smartwatch_dsn20_fastabs.pdf\" target=\"_blank\" rel=\"noopener\" data-ng-href=\"pdfs\/DSN-S2020-3C02563Dj8cxijanbjSmod\/726000a059\/726000a059.pdf\">The Effect of Motion on PPG Heart Rate Sensors<\/a><\/p>\n<p class=\"pl-lg\"><em class=\"ng-binding\">Daniel Hu (Purdue University), Calvin Henry (Purdue University), Saurabh Bagchi (Purdue University)<\/em><\/p>\n[B] <a class=\"text-bold ng-binding\" href=\"https:\/\/engineering.purdue.edu\/dcsl\/publications\/papers\/2020\/edge-mobility_dsn20_fastabs.pdf\" target=\"_blank\" rel=\"noopener\" data-ng-href=\"pdfs\/DSN-S2020-3C02563Dj8cxijanbjSmod\/726000a061\/726000a061.pdf\">Reliability Analysis of Edge Scenarios Using Pedestrian Mobility<\/a><\/p>\n<p class=\"pl-lg\"><em class=\"ng-binding\">Kshitiz Goel (Purdue University), Abhishek Bhaumick (Purdue University), Deepika Kaushal (Purdue University), Saurabh Bagchi (Purdue University)<\/em><\/p>\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Our work on reliability of wearable devices is featured in a Purdue news story.
