Improved Physical Layer Security in Visible Light Communications by Using Focused Light Emitters
(IEEE, 2021)
A conventional visible light communication system consists of a transmitter, a jammer that includes a few light emitting diodes, a legal listener and an eavesdropper. In this work, a similar system is designed with a ...
Research on Power Distribution Method of OFDM System with Hybrid Energy Supply under Fast Fading Channel
(IEEE, 2021)
An adaptive power allocation by minimizing grid power consumption for the Orthogonal Frequency Division Multiplexing (OFDM) system with the hybrid energy supply under a fast fading channel is proposed in this paper. To ...
NOMA-based Radio Resource Allocation for Machine Type Communications in 5G and Beyond Cellular Networks
(IEEE, 2021)
In this paper, the minimum bandwidth resource allocation problem for non-orthogonal multiple access (NOMA) based machine to machine (M2M) communications in 5G and beyond cellular networks is investigated. In order to solve ...
Increasing Energy Efficiency of WSNs Through Optimization of Mobile Base Station Locations
(IEEE, 2021)
In terms of enhancing overall energy usage, wireless sensor networks (WSNs) can run with minimal energy to extend their lifespan. Due to limited power resources, the optimal base station (BS) location could prolong the ...
Analysis of deep learning based path loss prediction from satellite images
(IEEE, 2021)
Determining the channel model parameters of a wireless communication system, either by measurements or by running electromagnetic propagation simulations, is a time-consuming process. Any rapid deployment of network demands ...
Children's thinking-for-speaking Bidirectional effects of L1 Turkish and L2 English for motion events
(John Benjamins Publishing Co, 2021)
This study investigates how children lexicalize motion events in their first and second languages, L1-Turkish and L2-English. English is a satellite-framed language that conflates motion with manner expressed in the main ...
Allocation of Distributed Generators Using Parallel Grey Wolf Optimization
(IEEE, 2021)
This paper solves the allocation problem of distributed generators (DGs) in smart grids utilizing a grey wolf optimization (GWO) algorithm. By parallelizing GWO, it presents the impact of using various number of processors ...
Application of fluorescence technique for understanding film formation from polymer latexes and composites
(Elsevier, 2021)
This chapter summarizes the application of fluorescence technique to understand all aspects of film formation using both pure polymer latexes and polymer nanocomposites. Transient fluorescence, steady state fluorescence, ...
An Improved Hybrid Stable Election Routing Protocol for Large Scale WSNs
(IEEE, 2021)
In the recent years, wireless sensor networks have become prevalent in a diverse range of applications. Throughout the massive usage of wireless sensor networks, some applications require sensing and/or data collection ...
Restructuring of the Media System and New Media Convergence
(Palgrave Macmillan, 2021)
In the aftermath of the Gezi protests and the 2015 elections, hundreds of media workers were laid off, and there was also a media purge in the aftermath of the coup attempt on 15 July 2016. The Doğan Media Group, which was ...
