Keyword: PropagationEvaluation of IEEE 802.11n and IEEE 802.11p based on Vehicle to Vehicle Communications
Wireless communication opens up new avenues in the field of intelligent vehicle systems, including monitoring, guidance and warning applications. In order to determine more precisely the feasibility of using the 802.11n standard in vehicular communication systems, this paper describes a process for evaluating the propagation performance of the 802.11n and 802.11p standards. To do that,…
Read MoreAssessment of Coordinated Multipoint Transmission Modes for Indoor and Outdoor Users at 28 GHz in Urban Macrocellular Environment
The aim of this article is to analyze and evaluate the performance of Coordinated Multipoint (CoMP) transmission approach at a frequency of 28 GHz using three dimensional ray tracing simulations in an urban macrocellular environment. The new performance metric introduced in this article is the relative power usage. Other performance metrics examined in this article…
Read MoreWireless Channel Measurement and Modeling in Industrial Environments
The Industrial Internet of Things (IIoT), a typical use case of the Internet of Things, has been a great prospect for development in the near future. In the developing fifth generation mobile communications, the IIoT is an extremely important application case. In this paper, the channel propagation properties are researched and modeled based on the…
Read MoreDesign of smart chess board that can predict the next position based on FPGA
The abilities of human brain to discover solutions for many problems is a great gift that motivate the scientists to develop the revolution of the artificial intelligence and using it in many areas. This paper proposed an intelligent chessboard which works in a way that similar to the human brain that predicts the next positions…
Read MoreAcoustic Signal Processing and Noise Characterization Theory via Energy Conversion in a PV Solar Wall Device with Ventilation through a Room
Noise defined as ‘a sensation of unwanted intensity of a wave’, is perception of a pollutant and a type of environmental stressor. The unwanted intensity of a wave is a propagation of noise due to transmission of waves (viz. physical agents) such as light, sound, heat, electricity, fluid and fire. The characterization of noise interference,…
Read MoreCyclical Wave Bolt for Sound Waves in a Gas Stream
This article is devoted to the problem of blocking the propagation of sound in a gas stream. This can be useful in the problems of pipeline acoustics and the design of automotive silencers, when it is necessary to ensure the opacity of the boundary (cross section of the pipe) for sound simultaneously with the free…
Read MoreAnalysis of Wireless Traffic Data through Machine Learning
The paper presents an analytical study on a wireless traffic dataset carried out under the different approaches of machine learning including the backpropagation feedforward neural network, the time-series NARX network, the self-organizing map and the principal component analyses. These approaches are well-known for their usefulness in the modeling and in transforming a high dimensional data…
Read MorePower requirements and battery life measurement for wireless transmission between two nodes in different mediums
One of the most important roles of the wireless sensor networks (WSN) is to avoid wiring costs, be self-sustainable and be able to function for several years. However, due to the slow progress in battery technology, power continues to be a limited resource in wireless sensor communication and electric energy storage remains to be an…
