homework ns2


In this homework, you are supposed to simulate a wireless network to illustrate the hidden node effect. Deploy the following topology of 5 nodes over a circle with radius R

https://www.linuxquestions.org/quest...7&d=1514144607

Deploy 4 different connections (you can deploy UDP or TCP with different type of traffics , but you must explain it in the results) from nodes 1, 2, 3, and 4 to node 0.

In the first simulation,you should choose R,such that the effect of hidden node terminals can be observed in this scenario. You should measure and draw the throughputs for all active connections and show how the hidden node effect degrades the throughputs. Then, activate the RTS and CTS packets to solve theproblem and show the results in different graphs.

Finally if nodes 3 and 4 move toward the center(as shown in the figure), find a position in which there is no hidden node problem.You should again draw the throughputs and show that there is no hidden node problem, even in the case where there is no RTS/CTS packet in the network.During all simulations, you should also generate a trace file and a NAM output files

newbe to what here, or programming? if programming, then why such a complex homework assignment?

if you are not new to programming then that assignment should show a lot more attempts at coding it other than, this is my home work, ( implied ) someone please do it for me. if that is not your intention, then it is just you showing us what your homework is, then I'd say, nice and good luck.

LQ Rules

Please take note of the following rule:
Quote:
  • Do not post homework assignments verbatim. We're happy to assist if you have specific questions or have hit a stumbling point, however. Let us know what you've already tried and what references you have used (including class notes, books, and searches) and we'll do our best to help. Keep in mind that your instructor might also be an LQ member.
If you will not put for any attempt to do your homework assignment and show some effort, members here cannot help you much. Persisting with asking for help in this manner may mean that you will not be able to participate in the LQ forum moving forwards.

If you are having trouble with homework ... "this is to be expected!"

(Speaking as an [adjunct-faculty ... community-college ...] instructor myself ...) "Please don't" just blindly turn to some web-site in search of an answer. Instead, sincerely attempt to do the homework yourself. And then, if you truly feel that you have hit-the-wall, "go to your instructor, and absolutely no one else," for further assistance!

Your instructor will give you additional guidance, and, in so doing, will also become aware of the fact that students in his/her class are having trouble in "this (whatever-it-is) particular aspect of the assignment." Now, they can know that maybe they need to address this issue, the next time the class meets. (Otherwise, they might have no idea.)

"Do not deny your instructor the opportunity to help you." Do not leave your instructor in the dark. The feedback that you give to your instructor(!) is, in fact, very essential to the overall objective of "teaching you (and your classmates)."

Always remember that the objective of "education" is not merely to enable you to "pass this course, today," but to empower you with the knowledge and the skills that you will need to successfully tackle similar problems in the future ... "on the job." The "educational" environment is a bit of a padded-cell that's designed to help you to learn these things, successfully and safely. Do not 'cheat' ... yourself!
