{"title":"Improving QoS in query-driven WSN using a cross-layered handover algorithm","authors":"G. Horvat, Jelena Vlaovic, D. Zagar","doi":"10.1109/MECO.2015.7181912","DOIUrl":"https://doi.org/10.1109/MECO.2015.7181912","url":null,"abstract":"Quality of Service (QoS) provisioning in Wireless Sensor Networks (WSNs) presents an open research issue within the scientific community because the rapid development of microelectronics proliferates new applications for WSNs. These applications often require a connection of end-to-end delay and high reliability for various communication models. Within this scope, a special class of WSNs are query driven WSNs where each node sends a query to the network sink, which expects a response to the query. As the application of query driven WSNs becomes versatile, the need to establish QoS support becomes intensely expressed, particularly for medium and high traffic loads. An experimental validation for query-based communication in a star configuration topology for various numbers of nodes and packet generation interval is performed within this paper. In existing WSNs, the QoS deteriorates upon increased traffic load due to congestion and the shared medium. This paper proposes a cross-layered handover algorithm in order to improve deteriorated performance and the QoS by means of multi-channel redundancy. Measurement results show that the proposed algorithm improves the delivery ratio by 25% and the RTT by 40% in the worst-case scenario. However, it underperforms upon the heavy traffic load where the trade-off is shown accordingly.","PeriodicalId":225167,"journal":{"name":"2015 4th Mediterranean Conference on Embedded Computing (MECO)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134439839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been known that the successful reconstruction of CS signals can be achieved using threshold based algorithm in the Fourier transform domain, based on just a small number of randomly chosen samples. The resulting signal has higher SNR compared to the input signal, which is used as a main premise of the proposed denoising solution. Namely, the signal denoising is done by averaging the reconstructed signal versions obtained in different iterations based on different subsets of random samples. The analysis of output SNR is done is terms of the number of iterations required for successful results. The influence of the number of random samples used in the iterations is analyzed as well. The proposed approach is illustrated on examples.","PeriodicalId":225167,"journal":{"name":"2015 4th Mediterranean Conference on Embedded Computing (MECO)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134242584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Medical devices in legal metrology","authors":"A. Badnjević, Lejla Gurbeta, D. Boskovic, Z. Dzemic","doi":"10.1109/MECO.2015.7181945","DOIUrl":"https://doi.org/10.1109/MECO.2015.7181945","url":null,"abstract":"In addition to knowledge and experience of medical doctors, correct diagnosis and appropriate patient treatment largely depend on accuracy and functionality of medical devices. In a large number of serious medical situations proper functionality of medical devices is crucial for patients. Therefore it is necessary to carry out as strict and independent testing of functionalities of medical devices as possible and to obtain the most accurate and reliable diagnosis and patient treatment. This paper presents the results of study conducted by the Institute of Metrology of Bosnia and Herzegovina (IMBIH) that highlight the necessity of introducing metrology into medicine and defining standard regulations for inspections of medical devices. As it has been previously done for other kinds of devices that are under jurisdiction of the Institute of Metrology of BH, this research provides a foundation for the introduction of medical devices into the legal metrology system with precisely defined units of measurement, their ranges and errors. The study was based upon data collected through three clinical centers, 25 hospitals, 63 health centers and 320 private health institutions in BH over the course of one year. As a result of this study, the medical devices that have been introduced into the legal metrology system in BH include ECG devices, defibrillators, patient monitors, respirators, anesthesia machines, dialysis machines, pediatric and neonatal incubators, therapeutic ultrasounds, infusion pumps and perfusors. Furthermore, standard inspection regulations for the aforementioned medical devices are also defined. Additionally, a national laboratory for the inspection of medical devices was established and it currently operates under the ISO 17020 standard. With the introduction of medical devices into the legal metrology system and with the establishment of a fully operational national laboratory for inspection of medical devices, we expect that the reliability of medical devices in diagnosis and patient care will increase and that the costs of the health care system in BH will be reduced.","PeriodicalId":225167,"journal":{"name":"2015 4th Mediterranean Conference on Embedded Computing (MECO)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124533686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
