Abstract

To endorse 5th generation communication networks, which have promising parameters like higher spectrum efficiency, larger massive connectivity, higher capacity gain, low latency, fewer interferences, good power efficiency, etc., a qualitative and authoritative access scheme has been nominated, i.e., Non-Orthogonal Multiple Access (NOMA). This paper describes an all encompassing look at different categories of NOMA signal transmission schemes (like scrambling, interleaving, spreading based, and coding based NOMAS), as well as some intent points of interference (like inter-cell and intra-cell interferences, etc.). The performance of different multiple accessing schemes of NOMA is summarized and the manifestations of interferences in 5G communications are enumerated in detail. This chronology provides anticipated evidence that the 5G spectrum will play a significant role in future communication networks.

Abstract

The smart parking system is one system where one can easily find out the details of the existing parking slots. Design and development of an IoT-based prototype system has been done for smart parking using Android technology. In this paper, a novel approach is incorporated by generating a directed path to identify the empty slot that minimizes the discovery time and fuel consumption. An application user interface has been developed for cloud data and for accessing realtime communication. The proposed system dynamically displays the availability of slots even from a remote location with the help of a mobile application. It consists of a sensing unit, a processing unit, a transmission unit, and an accessing unit. The presented work is a combination of the Internet of Things and Android technology.

Abstract

Carpooling is the process of sharing car journeys so that multiple people can travel in the same vehicle. Carpooling reduces fuel costs, tolls, and the stress of driving. Carpooling can help solve a range of issues, such as energy requirements and traffic congestion, as well as pollution. Authorities frequently encourage carpooling, particularly during periods of high pollution and high fuel prices. This paper proposes an Android-based application that will inform individuals if vehicles are available for carpooling on their selected route and allow them to sign up for it. This will allow users of the program to split costs without having to worry about hiring a cab or developing new contacts. People who have this program on their phones with advanced features can effortlessly carpool with strangers without fear of security. It provides a better way to pool an automobile in a very efficient and user-friendly environment.

Abstract

A mobile ad-hoc network (MANET) is a remote system that exchanges data from a source to a destination. This technology is now widely used all over the world since it does not require any fixed-wired system to establish communication between the source and the objective. The major threats to the mobile ad-hoc network include dark gap assaults and wormhole attacks. One of the most common attacks against mobile ad hoc networks (MANETs) is the gray hole attack, in which a hostile node promises to participate in route construction but then refuses to send data. The sensitivity of two popular ad hoc routing systems, Ad hoc On-Demand Distance Vector Routing (AODV) and Dynamic Source Routing (DSR) are investigated in this work. The Ad hoc On-demand Distance Vector (AODV) protocol is a common reactive routing technology that is vulnerable to the well-known packet dropping attack, in which a hostile node drops some packets without forwarding them to their intended destination. In this paper, the authors investigate how to protect packet dropping attacks in MANET using security measures such as data routing information (DRI) and cross-checking operations.

Abstract

This paper, brings up the fact that mobile devices are used in education for pupils with learning disabilities. Learning disability encompasses a wide range of execution areas in which an individual has complexity in learning as a characteristic; it is usually derived for specific reasons. Whereas learning disability, learning disorder, and learning difficulty are often used interchangeably, and they differ in many ways. Learning disabilities refer to considerable problems in educational culture. A learning disorder is an authorized medical diagnosis whereby the personality meets certain conditions as dogged by a specialist (psychologist, pediatrician, etc.) Learning disabilities are used to describe a group of disorders distinguished by insufficient growth of specific academic, language, and speech skills. It focuses on three types of learning disabilities: reading disability (dyslexia), mathematics disability (dyscalculia), and writing disability (dysgraphia). Mobile devices are not only used for overwhelming information but also resourceful education. It is associated with e-learning and is mostly used to improve individual learning. Progression in mobile technology will allow us to shift our focus to an enlightening atmosphere. Pupils with learning disabilities have trouble performing specific types of skills or completing tasks. They have experience with visually impaired students and teachers who utilize mobile phones as their learning devices. In an educational situation, the teachers and teacher educators provide more time for the children with learning disabilities and are patient with them. Children with learning disabilities were able to take their own time for learning and it enhanced their learning ability.
