Online transaction fraud detection has become a critical challenge with the rise of digital payment systems. This paper surveys various machine learning techniques employed in fraud detection, including Support Vector Machines (SVM-QUBO), Logistic Regression, K-Nearest Neighbors (KNN), Naive Bayes, Decision Trees, and Random Forest. The performance...

The number of Internet of Things (IoT) devices in smart homes is rising swiftly, producing enormous amounts of data that are mostly transmitted over wireless communication channels. IoT devices can be at risk from a variety of threats, such as hacker attacks, cyberattacks, erratic network connectivity, data leakage, etc. By evaluating vast amounts...

The army, navy, and many other scientific applications use oceanographic robots today, and they also make significant contributions to sustainable development. By keeping an eye on the water's physical and chemical characteristics, it hopes to protect underwater life and create a safe home for marine species. In this paper, an oceanic robot is buil...

Terahertz (THz) imaging is a non-invasive and high spatial-resolution technique that uses non-ionizing electromagnetic signals in a frequency range of 0.1–10 THz. Hence, this article focuses on diverse THz imaging techniques, THz antennas and designing methods, image reconstruction algorithms, and its applications. The antennas include planar patch...

This work presents a 12-element 360° azimuth plane scanning planar circular antenna array for compact THz wireless devices. Proposed array comprises of 12 bow-tie Yagi-Uda directional antennas, operating within 0.235–0.322 THz band where each antenna achieves a maximum radiation beam for an angle of around 30°, arranged in a circular fashion to cov...

This work presents a design of 10-element symmetric series fed non-uniform planar antenna array operating at 0.3 THz and exhibiting high directional radiation pattern along the upper hemisphere. An impedance bandwidth of range 0.294–0.313 THz and a peak gain (dBi) of 13.26 at 0.3 THz are noted. Gold material of thickness 5 µm and silicon dioxide (S...

A probe-fed circularly polarized stacked patch antenna is presented and simulated by using Commercial Ansoft High Frequency Structure Simulator. The design consists of two patches and two substrates. The bottom patch is square-shaped where as the top patch is of triangular-shaped. T-shaped slots parallel to the edges of the patches are inserted so...

A novel miniaturized design of a multiple slotted antenna is designed and simulation results are presented in this paper. The proposed antenna uses I-, U-and inverted L-shaped slots in the radiation patch. The resonance frequencies can be controlled by adjusting the dimensions of the slots. The proposed antenna can meet the demand of WLAN, HIPERLAN...

In wireless as well as networking communications technologies, VANETs have been developed as a result of the advances in the past few centuries. The traffic safety and efficiency can be improved by the usage of the VANET. A wireless communication device termed by means of an on board unit (OBU) is involved by each vehicle that functions using the I...

Our final aim is to implement a high energy economical information transmission protocol for Mobile adhoc network. We have got selected our analysis domain energy management system in MANET. Cooperative communication could be a hopeful technique for saving the energy consumption in MANETs. CC is not forever energy economical compared to transmissio...

A multi-band microstrip patch antenna is developed and presented in this paper. The radiating elements in this antenna are composed of rectangular and triangular slots. These slots are engraved in the rectangular and triangular patch, joined together in one structure, and by single probe feed. The rectangular and triangular slots make the antenna t...

This project explains about the energy efficiency (EE) maximization problem in multiple-input multiple-output (MIMO) two-way relay networks with continuous wireless information and power transfer (SWIPT). The network consists of a multiple-antenna amplify-and-forward relay node which provides bidirectional communications between two multiple antenn...

A novel miniaturized configuration of a different U-slotted micro-strip radio wire is outlined in view of focus recurrence about 4. 7 GHz with dielectric steady (εr) for 4. 4 also substrate thicknesses from claiming 2. 4mm. The suggested radio wire might meet the interest from claiming WiMax and wideband requisitions. The way parameters like return...

A probe-fed circularly polarized 3-layer stacked patch antenna is presented and simulated by using Commercial Ansoft High Frequency Structure Simulator. The design consists of three patches and three substrates. The lower and middle patches are of square-shaped where as the upper patch is of triangular-shaped. One slot is inserted in the lower laye...

Antenna arrays yield multiple, simultaneous available beams. These beams can be made to have high gain, low side lobes and controlled beam width. In conventional beam forming, the smallest beam width depends on the geometric dimensions of the receiving array. This problem may overcome by the Hyper beam invention. The linear array when implemented u...
