For example, the implantable cardioverter-defibrillator (ICD), which is used to maintain the heart in a healthy state, requires a reliable wireless communication scheme with an extremely low duty-cycle, high bit rate, and energy-efficient media access protocols. Because such devices must be sustained for over 5 years without access to battery replacement, they must be designed to have extremely low power consumption in sleep mode. Here, an on-time, energy-efficient scheduling scheme is proposed that performs power adjustments to minimize the sleep-mode current. The novelty of this scheduler is that it increases the determinacy of power adjustment and the predictability of scheduling by employing non-pre-emptible dual priority scheduling. This predictable scheduling also guarantees the punctuality of important periodic tasks based on their serialization, by using their worst case execution time) and the power consumption optimization. The scheduler was embedded into a system on chip (SoC) developed to support the wireless body area network\u2014a wakeup-radio and wakeup-timer for implantable medical devices. This scheduling system is validated by the experimental results of its performance when used with life-time extensions of ICD devices.<\/jats:p>","DOI":"10.3390\/s130100375","type":"journal-article","created":{"date-parts":[[2012,12,27]],"date-time":"2012-12-27T11:08:31Z","timestamp":1356606511000},"page":"375-392","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["An On-Time Power-Aware Scheduling Scheme for Medical Sensor SoC-Based WBAN Systems"],"prefix":"10.3390","volume":"13","author":[{"given":"Tae-Ho","family":"Hwang","sequence":"first","affiliation":[{"name":"Multimedia IP Center, Korea Electronic Technology Institute, 6th Fl., #22, Daewangpangyo-ro 712 Bundang-gu Gyeonggi-do, Seongnam-si 463-400, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7169-5028","authenticated-orcid":false,"given":"Dong-Sun","family":"Kim","sequence":"additional","affiliation":[{"name":"Multimedia IP Center, Korea Electronic Technology Institute, 6th Fl., #22, Daewangpangyo-ro 712 Bundang-gu Gyeonggi-do, Seongnam-si 463-400, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jung-Guk","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering, Hankuk University of Foreign Studies, Gyeonggi-do, Yongin-si 449-791, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2012,12,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Lo, B., and Yang, G.
