The ability to see through the walls via wireless signals has ushered in a new era. This technology has a wide range of applications, such as military, law enforcement, medicine, and games. Objective: This paper has concise Read More

Introduction: In this paper, a surface acoustic wave sensor (SAW) for dangerous gas sensing applications has been designed and validated. The glucose sensor applications have been simulated to show that the piezoelectric material has a high significance for use in detection. Background: Detection of gases is one of the major applications. SAW gas sensors extend their services into medical and even in power plants. A Surf Read More

Background: Agriculture sector is one of the prime and widely spread sectors. So to make it autonomous and increase its yield, we require a major technological improvement. The only solution to make advancement is with the use of wireless sensor networks. Internet of Things in this field is used to provide connectivity to all real-time sensors and to collect that data in computer-based systems without human involvement. Ob Read More

Background and Objective: Wireless sensor networks (WSN) consist of sensor nodes with a limited battery life and limited communication distance. The minimal energy expended by the sensor nodes and network can be achieved either by reducing the number of communications or by controlling the topology. Thus, energy consumption can be optimized by employing several techniques, such as clustering. Clustering all Read More

Background: Increasing demand for wireless devices leads to the efficient use of spectrum resources. Despite the limited availability of spectrum resources, all licensed users do not utilize their spectrum all the time. Objective: Cognitive Radio (CR) is used to detect free channels in the available spectrum resources and access them dynamically without interfering with licensed users. Various spectrum sensing (SS) techni Read More

Background: Trust and security are the biggest challenges facing the Cooperative Spectrum Sensing (CSS) process in Cognitive Radio Networks (CRNs). The Spectrum Sensing Data Falsification (SSDF) attack is considered the biggest threat menacing CSS. Methods: This paper investigates the performance of different soft data combining rules such as Maximal Ratio Combining (MRC), Square Law Selection (SLS), Square Law Co Read More

Background: Vehicular ad hoc networks (VANETs) are built on the principles of mobile ad-hoc networks, and there are numerous approaches to achieving vehicular communication, like vehicle to infrastructure or vehicle to vehicle, with the advantage of ad-hoc networks. In VANETs, both vehicle-to-vehicle and vehicle-to-roadside architecture coexist to provide safety, services, and navigation; therefore, they are an integra Read More

Background: Long-term evolution (LTE) is the fourth generation (4G) mobile communication technology developed by the 3rd Generation Partnership Project (3GPP). In comparison to previous generations of cellular systems, LTE incorporates several innovative technologies. These innovative technologies are used to increase spectrum efficiency and data speeds, as envisioned by designers. Methods: This study provi Read More
