    An evaluation of internet of nano-things simulators
    (Institute of Electrical and Electronics Engineers Inc., 2021) Şahin, Emre; Dağdeviren, Orhan; Akkaş, Mustafa Alper
    Nowadays, distributed systems consisting of a large number of simple devices are used to perform complex operations rather than advanced devices alone. Particularly, networked systems of nanoscale devices are called Internet of Nano-Things (IoNT). This new field has emerged with new problems to be solved where simulation of nanonetworks is one of these problems. In this study, Electromagnetic (EM) communication-based nanonetwork simulators used in IoNT applications are examined in detail to determine the advantages and their drawbacks. Different than the related studies, our contribution is a detailed and up-to-date roadmap for simulator selection for researchers working in different layers of nanonetwork applications such as channel modeling, antenna design, modulation methods, medium access control (MAC) protocols, and routing algorithms. © 2021 IEEE

    TeraHertz channel model for search and rescue nanonetwork applications in debris areas
    (Institute of Electrical and Electronics Engineers Inc., 2021) Şahin, Emre; Dağdeviren, Orhan; Akkaş, Mustafa Alper
    Disasters such as earthquakes cause thousands of deaths every year. Since it is not possible to predict such disasters, research has generally focused on search and rescue operations in the debris area after these disasters. Due to the structures of the debris areas, where there are very tiny gaps between the wracks, the use of large-scale advanced devices is very limited in these operations. On the other hand, nanodevices that can easily pass through these gaps and scatter into the debris area can be used to gather information from under the wreckage. The computing complexities and transmission ranges of nanodevices differ according to their size and the amount of energy they have. In this study, TeraHertz (THz) channel models in debris areas of different densities were investigated for different types of nanodevices. Our contribution is a detailed analysis of channel properties using 0.1-0.35 THz for debris areas in terms of transmittance, absorption loss and path loss. Moreover, a novel research topic is suggested for nanonetwork applications generally associated with biomedical and agricultural studies. © 2021 IEEE.
