Abstract

This paper aims to explore Machine Learning-based traffic prediction in 5G networks using the QualNet simulator and the Spatio-Temporal Long Short-Term Memory (STLSTM) model. The study evaluated the performance of the STLSTM model by comparing it with other models such as Long Short-Term Memory (LSTM), Gated Recurrent Unit (GRU), and Convolutional Neural Network (CNN). The evaluation metrics used for the simulation experiments included Packet Delivery Ratio (PDR), throughput, end-to-end delay, and jitter. The results showed that the STLSTM model outperformed the other models in terms of Root Mean Square Error (RMSE), Mean Absolute Error (MAE), and R-squared, and achieved improved accuracy in predicting traffic in 5G networks. The findings of this study can help network operators to effectively manage traffic and optimize network performance.

Abstract

Digitalization is becoming more and more important. Building smart houses and industries to offer humans longer lives is one of the main goals of the digitization movement. The main aim of this work is to make those verbal exchange modules more powerful with the aid of either improving the antennas to have a higher layout or changing it with new varieties of antennas that are better able to facilitate powerful verbal exchange. This paper proposes an antenna that can be applied to a verbal exchange module to be able to perform inside the Industrial, Scientific, and Medical (ISM) band at 2.4 GHz. After designing and simulating a complete Printed Circuit Board (PCB) antenna, it found that a few designs produced advanced simulation effects in terms of gain, reflection coefficient, voltage standing wave ratio (VSWR), and band width. Always-pointing antennae are protected by the layout of the antenna, allowing it to protect features inside the Global Positioning System (GPS) and ISM (Industrial, Scientific, and Medical) bands for Wi-Fi devices.

Abstract

The advent of mobile technology has brought about significant changes in many areas of life, including the management of food intake and dietary habits. This paper proposes an Android-based food automation and dietary management system that leverages the power of mobile technology to streamline the process of ordering and preparing meals in a hospital setting. The system includes a mobile app that allows users to place food orders and track their nutrient intake, as well as a dietary plan generator module that utilizes third-party Application Programming Interfaces (APIs) to create personalized meal plans based on individual dietary needs and preferences. It discusses the benefits of this system, including improved efficiency, accuracy, and patient satisfaction. Overall, this paper demonstrates the potential of mobile technology to transform the way it approaches food and nutrition in healthcare settings.

Abstract

Secure data transmission is one of the most difficult challenges of Mobile Ad hoc Networks (MANET), it is a group of wireless mobile nodes that creates a temporary network without the help of a centralized system, infrastructure, or access point. Location-Aided Routing (LAR) protocols limit the ad hoc network's search for a new route to a limited "request zone." For safe message transmission in the current Location Aided Routing protocol, the Secure Location Aided Routing algorithm (SLAR) is proposed in this paper. The LAR is a geographic routing protocol that establishes the route discovery region between the source and distance before forwarding the route request packets. SLAR is an extension of LAR where the performance of LAR is compared in the presence and absence of malicious nodes, and the security of LAR is improved by putting cryptographic features in it. SLAR has significantly improved throughput, end-to-end delay, and packet delivery ratio compared to LAR.

Abstract

With technology's increasing capabilities, social media has become the largest pool of data from which it can extract public opinion and begin to gather informative data on the success or failure of a brand, product, or marketing campaign in the eyes of the public. People share their experiences, opinions, and daily activities on social media, which results in enormous amounts of online data that attract developers to carry out data mining and analysis. Thus, there is a necessity for social media screening to obtain results that can be used for analysis. Twitter is an online networking site driven by tweets, which are 140-character limited messages. Thus, the character limit enforces the use of hashtags for text classification. Currently, around 5500–6000, tweets are published every second, which results in approximately 561.6 million tweets per day. Performing sentiment analysis of tweets can help us to determine the polarity and inclination of a vast population toward a specific topic, term, or entity. The applications of such analysis can easily be observed during public elections, movie promotions, brand endorsements, and many other fields. This proposed system uses a Naïve Bayes classifier to determine the tweets based on sentiment. In the implemented system, tweets are collected, and sentiment analysis is performed on them. Based on the sentiment analysis results, a few suggestions can be provided to the user. The primary aim is to provide a method for analyzing sentiment scores based on grades. This paper reports on the design of sentiment analysis, extracting vast numbers of tweets. Results classify users' perceptions via tweets into positive and negative categories. Secondly, it discusses various techniques to carry out a sentiment analysis on Twitter data in detail.
