<p>Currently, fast and efficient computing is driving the new disruptive technologies required by modern healthcare systems. A simulation model is presented that studies how virtualization affects the performance of task offloading in smart health-care environments. Virtualization technology is suitable for task-offloading processes. A simulation-based framework can be used to examine how virtualization overhead influences task offloading efficiency in smart healthcare environments. Therefore, the proposed model uses virtualization to manage resources more effectively and make the system more reliable. Important factors such as how long a task takes to finish, how much energy it uses, how much data it can handle, and how well it can grow when more tasks are added must be considered for smart healthcare. The results were compared with those of a system that did not use virtualization; thus, we can clearly observe how virtualization changes the overall performance. The findings show that better resource use, lower energy consumption, and improved fault recovery are possible, which makes the proposed system suitable for real healthcare applications. In the future, this work can be extended by adding predictive analytics, improving machine-learning–based scheduling, using multiple cloud platforms, and making virtualization even more energy-efficient.</p>
