Software‐defined networking (SDN) has received considerable attention and adoption owing to its inherent advantages, such as enhanced scalability, increased adaptability, and the ability to exercise centralized control. However, the control plane of the system is vulnerable to denial‐of‐service (DoS) attacks, which are a primary focus for attackers...

The innovative computing idea of Internet‐of‐Things (IoT) architecture has gained tremendous popularity over the last decade, resulting in an exponential increase in the connected devices and the data processed in the IoT networks. Since IoT devices collect a massive amount of sensitive information exchanged over the traditional internet, security...

There are continued advances in the internet and communication fields regarding the deployment of 5G-based applications. It is expected that by 2030, 6G applications will emerge as a continued evolution of the mobile network. Blockchain technology is one of the leading supporting technologies predicted to provide a secure and unique network to 6G-e...

With increased interest in 6G (6th Generation) cellular networks that can support intelligently small-cell communication will result in effective device-to-device (D2D) communication. High throughput requirement in 5G/6G cellular technology requires each device to act as intelligent transmission relays. Inclusion of such intelligence relays and sup...

The internet is widening day by day followed by security issues related to it. There are many approaches to achieve a secure cyber environment but still, there always exists room for the optimal choice to attain security goals. Artificial intelligence (AI) has given a new vision to the technology by implementing its remarkable applications for comm...

The revolutionary idea of the internet of things (IoT) architecture has gained enormous popularity over the last decade, resulting in an exponential growth in the IoT networks, connected devices, and the data processed therein. Since IoT devices generate and exchange sensitive data over the traditional internet, security has become a prime concern...

The dynamics of computer networks have changed rapidly over the past few years due to a tremendous increase in the volume of the connected devices and the corresponding applications. This growth in the network’s size and our dependence on it for all aspects of our life have therefore resulted in the generation of many attacks on the network by mali...

Measurement of vital signs of the human body such as heart rate, blood pressure, body temperature and respiratory rate is an important part of diagnosing medical conditions and these are usually measured using medical equipment. In this paper, we propose to estimate an important vital sign – heart rate from speech signals using machine learning alg...

The rapid advances in the internet and communication fields have resulted in a huge increase in the network size and the corresponding data. As a result, many novel attacks are being generated and have posed challenges for network security to accurately detect intrusions. Furthermore, the presence of the intruders with the aim to launch various att...

Heart rate is an important vital sign used in the diagnosis of many medical conditions. Conventionally, heart rate is measured using a medical device such as pulse oxymeter. Physiological parameters such as heart rate bear a correlation to speech characteristics of an individual. Hence, there is a possibility to measure heart rate from speech signa...

Discovering oral cavity cancer (OCC) at an early stage is an effective way to increase patient survival rate. However, current initial screening process is done manually and is expensive for the average individual, especially in developing countries worldwide. This problem is further compounded due to the lack of specialists in such areas. Automat...

This article provides a dataset as well as the procedure used to create the dataset which could be used to facilitate research in developing techniques to estimate heart rate accurately by observing speech signal.

Speech signals of individuals contain information related to their physical, mental as well as emotional health. A first step in clinical diagnosis is to measure vital signs, which provide an indication of vital body functions. The four vital signs - heart rate, blood pressure, body temperature and respiratory rate are useful in assessing the healt...

Vehicular ad hoc 1 networks (VANETs) have emerged as a new breed of Self-Organized Networks (SONs). In addition to the Vehicle-to-Vehicle and Vehicle to-RoadSide Units, it assumes that vehicular nodes are connected to other smart objects equipped with a powerful multi-sensor platform, communication technologies, computation units, and IP-based conn...

A dominant design issue of D/A converters is the accuracy, which relies on the matching capabilities of active or passive elements. A circuit that is well suited for this purpose is a R-2R ladder structure using MOS transistors instead of resistors.This paper aims to design an 8-bit Multiplying Digital to analog converter (MDAC) implemented using 9...

The emergence of Internet-of-Things (IoT) has attracted a massive response from different stakeholders including industry, academia and research community due to the wide range of applications it provides. IoT enables devices with storage, computation and communication capabilities to connect to the Internet, thus providing various applications suc...

Vehicular Adhoc Networks (VANET) is the backbone technology behind Intelligent Transportation Systems (ITS) which offers a plethora of safety and comfort applications. With their powerful computation and storage capacities, vehicles themselves can play the role of services producers, thus, realizing the concept of Vehicular Clouds (VC) within the n...

According to a study in 2010, epilepsy is a major neurological disorder affecting more than fifty million persons throughout the world. The incidence of epilepsy is over 6.54 for every thousand individuals in the Kingdom of Saudi Arabia. Epileptic seizures are fatal and may even lead to death. Thus, effective methods for seizure detection play a pr...

sa . ABSTRACT— The purpose of this study is to design and analyze a Finite Impulse Response (FIR) filter to program a Pre-modulation filter for avionic application.
