Abstract Extensive research in many directions on the Internet of Things (IoT) is currently undertaken. In this research we studied the possibility of a low-power monolithic DC converter for applying in the IoT environment. We have specified the possible maximum efficiency of the circuits and the input as well as output voltage. Using the CMOS technology, we have designed the DC... Read More


Architecture of Cloud based IoT Visualization

Neven Nikolov and Svetlin Antonov

https://doi.org/10.6025/ijwa/2021/13/3/77-83

Abstract An architecture based on cloud for communicating with Internet of Things Embedded systems is developed. The communication with synchronization with embedded system which can take the data from sensors is possible with cloud structure visualization. We have introduced and explained the various stages for designing the cloud-based IoT.... Read More


The Study of the Security Physical Layer with an Arbitrary Number of Sensors

Abstract We have measured the security physical layer of the system with an arbitrary number of sensors which send the sensed data to the sink. In this process we found that the eavesdropper tries to intercept the communication of each sensor-sink channel.We have assessed the intercept probability with round-robin and best-node sensors’ scheduling that provided the optimal sensor scheduling scheme so...
