A Review: OPNET Simulation for Wireless Networks Medical Data Transmission

In this review paper, we have critically reviewed several research studies that have used OPNET simulation tools to simulate, analyze, and optimize the performance of wireless networks for the transmission of medical data.There are growing dependencies on electronic health records (EHRs), telemedicine, and IoT enabled medical devices which have created a critical priority for healthcare system worldwide: the secure, reliable, and timely transmission of sensitive medical information.It also explores the latest trends, such as support for next-generation wireless standards (e.g., Wi-Fi 6/6E and 5G) and hybrid simulation approaches.By highlighting crosslayer optimization strategies and ways to converge experimental reading with simulation results in the real world, this review pinpoints important directions for future research.The paper summarizes these findings across multiple simulation studies and discusses using OPNET in health data communication, because its more secure, and efficient to accommodate the growing demands of the healthcare industry in the 21st century, where the results show that IPsec protocol achieves highest average throughput, reaching (100 Mbps, 85 Mbps, and 60 Mbps) for (Low, Medium, and high) traffic load respectively.
