This is a potential for running IoT applications containing multiple services taking benefit of closeness to fog nodes near to devices where the data are sensed. This article formulates service placement issue into an optimization problem with total power consumption minimization inclination. It considers resource utilization and traffic transmission between different services as two prominent factors of power consumption, once they are placed on different fog nodes. On the other hand, placing all of the services on the single fog node owing to power reduction reduces system reliability because of one point of failure phenomenon. In the proposed optimization model, reliability limitations are considered as constraints of stated problem. To solve this combinatorial problem, an energy-aware reliable service placement algorithm based on whale optimization algorithm (ER-SPA-WOA) is proposed. The suggested algorithm was validated in different circumstances. The results reported from simulations prove the dominance of proposed algorithm in comparison with counterpart state-of-the-arts. پرونده مقاله -

The present stu چکیده کاملInternet of things (IOT) technology is being quickly expanded, advanced, and implemented in developed countries. In this situation, Denmark is considered an instance of successful implementation and application of IOT in terms of the connected equipment. The present study investigates the issue of IOT and sustainable development focusing on its environmental effects in Denmark. The research has been done by analytical citation referring to the papers and reports published in Denmark. Study of the resources shows that IOT has realized the goals of sustainable development in the area of environment. Several components including waste management, reduction of pollution and wastes, supplying renewable energies, reduction of carbon production and greenhouse gas emission, energy efficiency, saving energy, and reduction of pollutants have been extracted from the reviewed literature. The results suggest that regarding the use of fuel consumption planning and traffic information, IOT can decrease fossil fuel consumption and pollutants in transportation area. In general, achieving the mentioned goals makes it possible to create environmentally-friendly cities that are favourable places for living. پرونده مقاله -

Regulatory, moral, and technological barriers related t چکیده کاملThe use of innovations to interact with the world has had a profound impact. In biomedical systems such as healthcare, diagnosis, prevention, therapy, and monitoring, IoT-based biomedical applications are employed. Regulatory, moral, and technological barriers related to biomedical technology are preventing the development of the medical IoT. Medical IoT is developing in terms of biological hardware and tracking data including physiological metrics, electrical impulses, and cancer signs. It is anticipated that in the next years, medical IoT will replace antiquated healthcare systems. Biomedical engineers can use IoT technology, but more study is needed before these technologies become ubiquitous for physicians and healthcare practitioners. This paper's findings are intended to better prepare biomedical engineers to lead and supervise multidisciplinary research endeavors. پرونده مقاله -

8 - A Novel Selfish Node Detection Based on Fuzzy System and Game Theory in Internet of Things
Gholam Hossein Abdi Amir Hosein Refahi Sheikhani Sohrab Kordrostami Shahram BabaieInternet of Things describes a large number of devices (things) are connected through a number of sensors via Internet, and lack of some nodes cooperation in providing service to other nodes might interrupt the connection of some things, decreasing network efficiency. A چکیده کاملInternet of Things describes a large number of devices (things) are connected through a number of sensors via Internet, and lack of some nodes cooperation in providing service to other nodes might interrupt the connection of some things, decreasing network efficiency. A multi-phase mechanism based on fuzzy logic and Game theory has been designed to recognize and motivate the selfish and malicious nodes to cooperate in IoT. In the first phase, the nodes are grouped into clusters with cluster-heads for data collection. In the second phase, a multiply and dynamic game is executed while forwarding their data packet or others’ data packet. Nodes can select their strategy when data packet forwarding in the third phase (Fuzzy logic). Nodes will determine the neighboring node reputation by using fuzzy system. The amount of reputation of each of the nodes has been realized and finally, with the help of second phase and fuzzy logic, each node is decided to be cooperate or selfish nodes and in case of head, clusters and fuzzy logic in some cases, the opportunity node will be reestablished to cooperate in network activities otherwise the node will be isolated. The simulation of the proposed method has been evaluated and the parameters of selfish node detection accuracy 5%, false positive rate 8% and packet delivery rate 12% are perform better than other previous methods. . پرونده مقاله
