A compact multiband monopole antenna with four L-strips and microstrip feed is proposed for mobile phone, S-band, Wireless Local Area Networks, and X-band applications. The antenna is simulated on a Flame Retardant-4 (FR-4) epoxy substrate with a dielectric constant of (εr)= 4.4 and loss tangent of 0.01. The antenna is simulated using High-Frequency Structure Simulator (HFSS) software. The antenna consists of four L-shaped cuts in the patch, with the ground plane acting as the monopole radiator. The total miniaturized size of the antenna is 30 × 30 × 0.8 mm3, and the monopole ground plane size is 30 × 6 mm2. The proposed antenna has better performance in terms of total peak gain compared to other similar antennas. It is a compact and efficient antenna with good performance. It can be used for a variety of applications, such as mobile phones, wireless communication devices, and radar systems.
Wireless networks have become an integral part of modern life, offering seamless connectivity and supporting various applications. However, achieving accurate node localization remains a significant challenge, particularly in environments where signal propagation is affected by obstacles, reflections, and interference. To address these challenges, a dynamic triangular algorithm method is proposed for node localization. This novel model aims to enhance the throughput, data rate, and efficiency of wireless communication systems in both Line-of-Sight (LOS) and Non-Line-of-Sight (NLOS) scenarios.

The Next Generation Network (NGN) is a telecommunications system that converges all services and information into packets for transfer, accommodating technical advancements high-speed and diversified services through its multilayer architecture. The NGN enables users to consistently and efficiently obtain services, and 5G cellular communication is a viable technology to meet the demand for high data rates in the future, particularly with its mmwave capacity. However, one of the major problems that the new generation faces is non-line-of-sight status, which results from higher frequencies' extreme vulnerability to interference from obstructions and misalignment. This special property makes it more difficult for the widely used Transmission Control Protocol (TCP) to achieve good throughput and low latency across an equitable network. TCP must modify the congestion window size in accordance with the state of the network, but it is unable to effectively adapt to its congestion window, resulting in degradation of the protocol's throughput. This research presents an in-depth analysis of trustworthy communications in 5G networks, examining how TCP affects 5G mmWave networks, the mechanisms and parameters of TCP that portrays the behavior of 5G networks, and a study of the existing problems, and ideas to be fixed. It also suggests a viable study of different methods to enhance reliable communications in 5G networks.
The main purpose of Wireless Sensor Networks (WSNs) is to collect data from unsafe environments. Almost all WSN security protocols assume that an adversary may gain complete control of a sensor node through direct physical access. As sensor networks emerge as a key technology in the future, researchers have faced a number of challenges. A wireless sensor network is made up of many tiny sensor nodes that operate independently and, in some cases, have no access to renewable energy sources. Additionally, as security is essential to the acceptability and use of sensor networks for a variety of applications, there are a number of challenges with sensor networks. This research focuses on the issues in Wireless Sensor Networks.
