This manuscript investigates the system performance of hybrid wireless and power line communication networks for indoor Internet of Things applications. Differentiating itself from the existing literature, the performance of the direct link and dual-hop energy harvesting relay-aided links is analyzed under the condition of indoor fading modeled by...

With the increased number of Software-Defined Networking (SDN) installations, the data centers of large service providers are becoming more and more agile in terms of network performance efficiency and flexibility. While SDN is an active and obvious trend in a modern data center design, the implications and possibilities it carries for effective an...

The technologies of the Internet of Things (IoT) have an increasing influence on our daily lives. The expansion of the IoT is associated with the growing number of IoT devices that are connected to the Internet. As the number of connected devices grows, the demand for speed and data volume is also greater. While most IoT network technologies use cl...

The objective of this paper is to study the performance of a cognitive radio network (CRN) under the influence of an eavesdropper (EAV) which can wiretap the primary user (PU) communication. In this CRN, the secondary transmitter (SU)’s transmit power is susceptible to the collaborative constraint of its peak transmit power. Consequently, the autho...

The paper deals with designing and implementation of a probe that measures the quality of Sigfox radio network coverage. This probe consists of the mobile application for Android operation system, Sigfox RF module, and Bluetooth module. Finding the coverage quality is solved by wireless communication between mobile device and Sigfox module, which s...
