    Usability of mobile voting with NFC technology
    (Acta Press, 2010) Ok, Kerem; Coşkun, Vedat; Aydın, Mehmet Nafiz
    Voting is a method to select one opinion or a person often following discussion, debate or an election campaign. After centuries of paper based voting ballots, electronic voting is used along with various technologies. One of the promising technologies is Near Field Communication (NFC) which allows data transfer between NFC-enabled devices and smart tags within a short distance. In this paper, we have presented a new type of a secure voting system, namely NFC voting, and evaluated the system's usability in a university council election with an executable prototype. Among other findings, we found that NFC voting satisfies electronic voting requirements and further increases the subjective usability of the proposed system.

    Demo abstract: TeleHealth - Intelligent healthcare with M2M communication module
    (ACM, 2012-11-06) Ayyıldız, Cem; Erman, Kamil; Özgül, Mehmet Emin; Tüysüz Erman, Ayşegül; Güngör, Çağrı
    Chronic diseases, such as diabetes, heart disease (e.g. arrhythmia and hypertension), chronic respiratory diseases (e.g. asthma and COPD), are by far the leading cause of mortality in the world, representing 63% of all deaths. Out of the 36 million people who died from chronic disease in 2008, nine million were under 60. Remote patient monitoring is an efficient and cost-effective solution to mitigate this problem. The key technology to facilitate wireless mobile healthcare or TeleHealth is cellular based M2M (machine-to-machine) communication. In this demo, we present a M2M Communication Module and its healthcare application developed at Turkcell Technology, Applied Research Lab.

    Improving age of information in random access channels
    (Institute of Electrical and Electronics Engineers Inc., 2020-07) Atabay, Doğa Can; Uysal, Elif; Kaya, Onur
    We study Age of Information (AoI) in a random access channel where a number of devices try to send status updates over a common medium. Assuming a time-slotted scenario where multiple transmissions result in collision, we propose a threshold-based lazy version of Slotted ALOHA and derive the time average AoI achieved by this policy. We demonstrate that the average AoI performance of the lazy policy is significantly better than Slotted ALOHA, and close to the ideal round robin benchmark.

    Near Field Communication: From theory to practice
    (John Wiley and Sons, 2011-12-27) Coşkun, Vedat; Ok, Kerem; Özdenizci Köse, Büşra
    This book provides the technical essentials, state-of-the-art knowledge, business ecosystem and standards of Near Field Communication (NFC)by NFC Lab - Istanbul research centre which conducts intense research on NFC technology. In this book, the authors present the contemporary research on all aspects of NFC, addressing related security aspects as well as information on various business models. In addition, the book provides comprehensive information a designer needs to design an NFC project, an analyzer needs to analyze requirements of a new NFC based system, and a programmer needs to implement an application. Furthermore, the authors introduce the technical and administrative issues related to NFC technology, standards, and global stakeholders. It also offers comprehensive information as well as use case studies for each NFC operating mode to give the usage idea behind each operating mode thoroughly. Examples of NFC application development are provided using Java technology, and security considerations are discussed in detail. Key Features: Offers a complete understanding of the NFC technology, including standards, technical essentials, operating modes, application development with Java, security and privacy, business ecosystem analysis Provides analysis, design as well as development guidance for professionals from administrative and technical perspectives Discusses methods, techniques and modelling support including UML are demonstrated with real cases Contains case studies such as payment, ticketing, social networking and remote shopping This book will be an invaluable guide for business and ecosystem analysts, project managers, mobile commerce consultants, system and application developers, mobile developers and practitioners. It will also be of interest to researchers, software engineers, computer scientists, information technology specialists including students and graduates.
