What are the benefits and drawbacks of using NS2 or OPNET to simulate a mobile network?

Specifically, when considering the simulation of mobile networks, different tools such as OPNET and NS2 are highly proficient, but both have their specific advantages, shortcomings, and characteristics. Based on the particular requirements of your simulation, you can select the appropriate tool by interpreting these aspects in an explicit manner.

NS2 Advantages

1. Open Source and Free: NS2 can be easily and freely accessible by students and researchers because it is openly-available software. In terms of certain research requirements, this tool enables for adaptations and alterations.
2. Broader Community Support: The NS2 software has a wide range of user committees, including an extensive history in research as well as educational-based environments. For assistance purposes, it offers an enormous amount of reports, external materials, and conferences.
3. Wide Protocol Support: This software is more appropriate for the simulation of different kinds of networks like mobile and wireless networks, by means of providing a vast array of protocols.
4. Adaptable and Extensible: Note that NS2 can be widely expanded with novel characteristics and protocols that could be created by the user committee, because of the category of openly-accessible software.

NS2 Disadvantages

1. Steep Learning Curve: Dealing with NS2 can be very intricate for learners, due to the need for knowing its TCL scripting language and C++, especially to append novel modules.
2. Outdated User Interface: When compared to the most current simulation tools, the visualization abilities and interface of NS2 are examined as out-of-date.
3. Performance Challenges: NS2 can require more sources and be slow for the process of simulating extensive ones, because of its structure and software period.

OPNET (Riverbed Modeler) Advantages
