Implementing Visible Light Communication in Intelligent Traffic Management to...ijceronline
Véhiculer Traffic is an inevitable phenomenon which is directly linked with the urban developmental society and cannot be ignored as it acts as a nervous system to the society in general and individuals in particular. Urban Traffic is emerging as an incurable threat to the modern society as there is a lack of efficient intelligent traffic management system. Prior attempts to use radio frequency spectrum, ultrasonic sensors and other alternatives proved to be ineffective as they are becoming crowded, that forced to develop an alternate means like wireless communication which can accommodate the exponentially increasing traffic demand. In this proposed research initiative, a Visible Light Communication (VLC) system is analyzed on its capabilities to provide an alternative to the current standards of wireless transfer of information using light from LEDs as the communication medium. The proposed system based upon the blinking of light-emitting diodes at a rapid rate such that the human eye will not notice the change in light illumination but a highly sensitive photodiode can read the behavioral changes and decode the information embedded within it. The proposed VLC methodology is also being tried to get implemented in intelligent wireless traffic management to resolve traffic logjams that usually occur in metro cities.

The Li-fi technology was invented by Professor Harald Hass of University of Edinburgh. Li-Fi has more capacity in terms of bandwidth in visible region therefore it does not poke its nose in other communications which uses radio frequency range, without taking its frequency bands. Li-Fi has thousand times greater speed than Wi-Fi and provides security as the visible light is unable to penetrate through the walls, which propose a new era of wireless communication. The concept of Li-Fi is data communication on fast flickering of light which is not detected by human eye but it is focused on photo detector which converts the on-off state into binary digital data. It has gained a huge popularity in two years of its invention. Such technology has brought not only greener but safer and cheaper future of communication.

Secure communications over wireless broadcast networkspraveen369
The document describes a shortest seek first algorithm for scheduling requests on a disk drive. The algorithm scans the request queue for the request closest to the disk head's current position and services that request first to minimize seeking time. While this reduces average response time compared to a FIFO queue, requests further away could starve if new requests keep arriving near the head.

Multi-carrier generation is the main building block for generating WiMax signal. In order to use WiMax signal in radio over fiber applications the use of all
optical generation of RF signals is required. To generate multi carriers optically, the system consisting ofseries of microring resonators (MRRs)
incorporating with an add/drop filter system are used. Thus the high frequency (THz) solitons range of 193.29–193.35 THz at frequencies of 193.333,
193.3355 and 193.3388 THz with the free spectralrange of 2.5 and 5.8 GHz could be performed using MRRs, providing required WiMax signal used in
wired/wireless communication. The generated multi carriers are multiplexed with the single carrier soliton and transmitted through single mode fiber (SMF)
after being beaten to photodiode, a WiMax signal is propagated wirelessly in transmitter antenna base station and is received by the second antenna located
in the receiver.

Magnetic resonance coupling for 5G WPT applicationsjournalBEEI
Inductive Wireless Power Transfer (IWPT) is the most popular and common technology for the resonance coupling power transfer. However, in 2007 it has experimentally demonstrated by a research group from Massachusets Institute of Technology (MIT) that WPT can be improved by using Magnetic Resonance Coupling Wireless Power Transfer (MRC WPT) in terms of the coupling distance and efficiency. Furthermore, by exploiting the unused, high-frequency mm-wave band which are ranging from 3~300 GHz frequency band, the next 5G generations of wireless networks will be able to support a higher number of devices with the increasing data rate, higher energy efficiency and also compatible with the previous technology. In this work, a square planar inductor with the dimension of 6.1 x 6.1 mm is designed, and the resonators have the same self-resonance frequency at 14 GHz. The coil resonators have been laid on Silicon and Oxide substrate to reduce the loss in the design. From the CST software simulation and the analytical model in MATLAB software, it has been shown that the MRC WPT design has improved the performance of IWPT design by 40% power transfer efficiency. MRC WPT design also has larger H-Field value which is 705.5 A/m, as compared to the IWPT design which has only 285.6 A/m when both Transmitter(Tx) and Reciever(RX) is at 0.3 mm coupling distance.
Machine learning based lightweight interference mitigation scheme for wireles...TELKOMNIKA JOURNAL
The interference issue is most vibrant on low-powered networks like wireless sensor network (WSN). In some cases, the heavy interference on WSN from different technologies and devices result in life threatening situations. In this paper, a machine learning (ML) based lightweight interference mitigation scheme for WSN is proposed. The scheme detects and identifies heterogeneous interference like Wifi, bluetooth and microwave oven using a lightweight feature extraction method and ML lightweight decision tree. It also provides WSN an adaptive interference mitigation solution by helping to choose packet scheduling, Acknowledgement (ACK)-retransmission or channel switching as the best countermeasure. The scheme is simulated with test data to evaluate the accuracy performance and the memory consumption. Evaluation of the proposed scheme’s memory profile shows a 14% memory saving compared to a fast fourier transform (FFT) based periodicity estimation technique and 3% less memory compared to logistic regression-based ML model, hence proving the scheme is lightweight. The validation test shows the scheme has a high accuracy at 95.24%. It shows a precision of 100% in detecting WiFi and microwave oven interference while a 90% precision in detecting bluetooth interference.
This document summarizes a paper presented at the 2023 International Conference on Computer Communication and Informatics. The paper proposes a novel interference mitigation technique and signal prediction method for future wireless communication. It discusses using IDMA (interleaved division multiple access) which improves error rate performance by suppressing interference. It also evaluates using Elliot wave theory to predict mobile signal strength without requiring extra hardware. Simulation results show IDMA with space-time transmit diversity and 256 quantization levels achieves a 10^-4 bit error rate at -0.5 dB. The paper concludes IDMA is a promising technology but further research is needed to explore its potential.
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation w...IJCNCJournal
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.
PARTICLE SWARM OPTIMIZATION–LONG SHORTTERM MEMORY BASED CHANNEL ESTIMATION WI...IJCNCJournal
The document summarizes a research paper that proposes a Particle Swarm Optimization–Long Short-Term Memory based channel estimation method (PSO-LSTMEstNet) for wireless sensor networks and Internet of Things applications. The key points are:
1. PSO-LSTMEstNet uses a PSO algorithm to optimize the input weights of an LSTM network for channel estimation. This allows the model to dynamically adapt to changing channel conditions.
2. A hybrid beamforming approach is used to group users based on their channel conditions. PSO then estimates the network characteristics after an initial channel parameter approximation from received data.
3. An evaluation shows PSO-LSTMEstNet enhances bit error rate performance over
The document discusses vehicle-to-vehicle (V2V) communication and proposes using ultrasonic sensors, ZigBee technology, and buzzers to enable communication between vehicles. It describes how ultrasonic sensors would work to measure distance and outlines some key features of ZigBee for wireless transmission of sensor data. The goal is to develop a cooperative collision warning system to help prevent accidents by providing early alerts to drivers. Future work may involve using GPS, WiFi, cameras, or signals from traffic boards to expand communication capabilities.
