Secure Virtual Reality Streaming Under Attack: Fine-Grained Modeling of the Latency Security Trade-Off Raghad Hazim Saeed, Qutaiba I. Ali, Farhad E. Mahmood International Journal of Safety and Security Engineering, 2026 Virtual Reality (VR) streaming systems require ultra-low latency and high throughput to maintain immersive user experiences, yet these requirements make them highly vulnerable to cyberattacks such as Distributed Denial-of-Service (DDoS) and Man-in-the-Middle (MitM).This creates a fundamental challenge in balancing strong security mechanisms with strict real-time performance constraints.This paper presents a latencyaware analytical framework and secured VR streaming architecture that quantitatively models the trade-off between cybersecurity and system performance under adversarial conditions.The proposed approach integrates transport layer security (TLS) 1.3/ Datagram TLS (DTLS), AES-256 encryption, and HMAC-based authentication within a VR streaming pipeline, and introduces a unified model that captures the effects of attack amplification and defense efficiency on end-to-end latency and application goodput.To validate the model, a controlled simulation of a 5-minute VR session over a Wi-Fi 6 environment is conducted, including a DDoS-style traffic flooding scenario.The evaluation compares four configurations: baseline, under attack, secured, and optimized secured.Results show that while attacks significantly increase latency and degrade throughput, the secured architecture maintains stable performance with only moderate overhead (30-32 ms latency), and the optimized configuration further reduces latency to approximately 25 ms while preserving security guarantees.Unlike existing VR security approaches that focus on isolated attack detection or privacy protection, the proposed framework provides a quantitative and system-level perspective on the securityperformance trade-off.The model can support the design and optimization of real-world VR streaming systems, enabling secure and responsive operation in emerging immersive applications.
Novel Four-Port Diplexer–Antenna System with Simultaneous Isolation Enhancement and Impedance Control Saad Wasmi Osman Luhaib, Farhad E. Mahmood, Shamil H. Hussein Journal of Communications Software and Systems, 2026 This paper presents the design and simulation-based performance evaluation of a novel four-port diplexer–antenna system that simultaneously achieves high transmit/receive isola tion and robust impedance control. Two compact parallel-coupled microstrip bandpass filters operating at 2.0 GHz (Rx) and 2.4 GHz (Tx) were synthesized using Chebyshev low-pass prototypes and umerically modeled on a Rogers substrate RO3006 (ϵr = 6.5, h =1.27 mm,tanδ =0.002). The filters were integrated into a four port diplexer topology employing a 180o phase-inversion path to exploit amplitude-and-phase cancellation, thereby reducing filter order and insertion loss while enhancing port-to-port isolation. Full-wave simulations and parametric analyses reveal that the proposed design yields an isolation of 50 dB at 2 GHz and 78.5 dB at 2.4 GHz, representing a substantial improvement over conventional single-filter configurations. Furthermore, the system’s isolation performance was evaluated under realistic an tenna impedance variations; results show the design retains high isolation despite shifts in both the real and imaginary components of the antenna impedance, with the Tx port demonstrating particularly strong resilience near the matched condition. These f indings verify that the co-optimized diplexer–antenna approach effectively mitigates impedance mismatch effects, offering a compact and low-loss solution for modern multi-band wireless front ends requiring stringent Tx/Rx isolation.
Breaking Barriers in-Vivo THz Communication Analysis for Nano Networks in Human Tissues Ban A. Asi, Farhad E. Mahmood, Nada I. Najim Periodica Polytechnica Electrical Engineering and Computer Science, 2025 Body Nano-Communication based on RF radio communication in the terahertz band supports health and fitness industry applications. Nano communications primary facilitate real-time monitoring of biological and chemical substances inside the human body, helping an early detection of stroke and heart attack risks. Monitoring small communication range inside the human body via electromagnetic propagation is not an easy task; thus, in this paper, we investigate the path loss of radio propagation in three human tissues: blood, skin, and fat using a Tera-Hertz frequency range in between 0.5 and 1.5 THz. The results support the idea that the path loss inside the human body depends on the dielectric loss of human tissues and the function of frequency and distance. It also shows that increasing the distance and the frequency of the signal inside the tissues, such as blood, fat, and skin, the path loss increases because the attenuation increases when the frequency increases. Furthermore, the study examines the effect of Doppler as a method of measuring the speed of blood flow to predict the early risks being considered.
Collaborative Intrusion Detection System to Identify Joint Attacks in Routing Protocol for Low-Power and Lossy Networks Routing Protocol on the Internet of Everything Omar A. Abdulkareem, Raja Kumar Kontham, Farhad E. Mahmood Mesopotamian Journal of Cybersecurity, 2024 The Routing Protocol for Low-Power and Lossy Networks (RPL) routing protocol is utilized in the Internet of Everything (IoE) is highly vulnerable to various collaborative routing attacks. This attack can highly degrade network performance through increased delay, energy consumption, and unreliable data exchange. This critical vulnerability necessitates a robust intrusion detection system. This study aims to enhance a Collaborative Intrusion Detection System (CIDS) for detecting and mitigating joint attacks in the RPL protocol, focusing on improving detection accuracy while minimizing network delay and energy usage. A series of algorithms and techniques are implemented, including Queue and Workload-Aware RPL (QWL-RPL) for congestion reduction, weighted random forward RPL with a genetic algorithm for load balancing, fuzzy logic for trust evaluation, and Light Gradient Boosting Machine (GBM) for attack detection. Additionally, Q-learning with a trickle-time algorithm is used to classify and manage joint attacks effectively. Numerical analysis indicates that the proposed approach performs better than existing methods in multiple metrics, including accuracy, energy consumption, throughput, control message overhead, precision, and computing time. By integrating these diverse techniques, the proposed CIDS offers a scalable and efficient solution to improve the security and performance of RPL-based networks in IoE environments, outperforming current approaches in detection accuracy and resource optimization.
Voltage and Reactive Power Control Approach to Address Over-Voltage Issues in High PV Penetration Networks Mohammed Kdair Abd, Rasool M. Imran, Layth F. Kamal, Farhad E. Mahmood, Firas M. F. Flaih International Journal of Electrical and Electronics Research, 2024 High energy penetration through photovoltaic (PV) panels poses a significant challenge due to over-voltage problems. This article presents a new approach for controlling the rise of voltage in low voltage Micro-grids (LVMg) with relatively high PV penetration (HPVP) named voltage/reactive power control (VRPC). The control is set via an inverter that uses the point of common coupling (PCC) voltage and returns it to its reference voltage via controlling of reactive power. Furthermore, the network in which the proposed method is considered have a high X/R ratio to emulate the LVMg. The proposed approach was implemented using MATLAB/Simulink environment and OpenDSS co-simulation. The simulations demonstrated that the VRPC/BESS technique has proven effective and robust in regulating voltage under HPVP operating conditions at various levels, where the rate of voltage rise was reduced by 5.6776% during 90% of HPVP. The proposed method can be considered fully robust and ready for widespread implementation.
Long-Term Solar Irradiance Forecasting Using Multilinear Predictors Abdulamjeed Sulaiman, , Farhad E. Mahmood, Sayf A. Majeed International Journal of Electrical and Electronic Engineering and Telecommunications, 2023 As the demand for crude oil is increasing every day, prices and pollution are both increasing in return, which has harmful effects on the environment. Thus, more attempts are being made to develop clean energy to rescue the planet and provide humanity with a cleaner energy source. As the renewable energy sector grows, new issues and challenges have emerged. Instability in electricity production from wind turbines, solar power plants, and dams creates challenges for energy transmission and storage systems. In order to achieve a more reliable and effective energy system, machine learning techniques have been used to forecast energy changes. Predicting the sun's Global Horizontal Irradiance (GHI) is one of the machine learning applications used in that sector. In this paper, many machine learning methods have been utilized, such as linear regression and long-short term memory (LSTM) methods to have long term GHI forecasting. Moreover, the significance of this paper is located in the way of prediction of the GHI irradiance prediction by using different levels of the linear regressors to find the best regressor level that provides the minimum error for the testing set based on cross-validation. Results showed that the regressor method provides a lower error compared with a single vanilla LSTM system for a shorter time computationally.
