Generally, NS3 wireless communication is expected to enhance with personal media employment and mobile devices. Though it has several technological improvements in real-world applications, it is still under the research of achieving effective radio spectrum utilization. Since it is not cost-effective and restricted in utilization. In future wireless network technologies, the combo of enhanced spectrum reusability and efficiency may solve these issues.

This page will deliver you the most important details about NS3 Wireless simulation along with innovative Research Ideas!!!

When we implement the unproved algorithms and protocols in a wide-range real environment, then it is not an effective approach in terms of cost and expected results. So, simulation is mandatory to evaluate the network performance in advance before the direct deployment. At the end of the simulation, if the simulated results reach a satisfactory level, then it is effective to launch in a real environment. And, one more method is validating and verifying the developed models in the physical tested through analytical modeling technique using NS3 Wireless Simulation. Below, we have given you few implications of a wireless link in real-world scenarios.
