computer network using NS-2

have a computer network assignment i hope someone can help me with. I am willing to pay for assistance.
The main objectives of the laboratory course are to provide students with essential skills to successfully simulate analyse and verify various networked systems. The NS-2 is open source software that is widely used both in research community and academic institutions for the above purposes. The contents of the course are organized in a manner as follows: it first serves to familiarize the student with the software environment and exploration of its capabilities. Secondly, the elements learnt in the earlier period are used to simulate and analyse realistic network technologies. It is anticipated that, after this course students will be able to use the software tools to perform independent study of various advanced network technologies.
i have done the analysis of the coding and for each task i need some expert to help me and go through my report and check it if it does match the requirement or noe
make it better and stronger.
add screenshot for every and each task and discuss about the network
