In this paper, we simulate throughput of mobile ad hoc networks with IEEE 802.11 over fading channels with impulse noise, and consider two cases: 1) the system with ARF algorithm and 2) the system with fixed rate. The simulated results show that the system with ARF algorithm has the similar throughput of 11 Mbps when the channel is AWGN without impulse noise. However, the system with ARF algorithm has the like throughput of 1 Mbps when the channel is Rayleigh without or with impulse noise. In addition, we consider that velocity ranges of stations impact on throughputs. The simulation results show that the throughput is worse than others when the velocity range is larger.References

The journal is currently an open access journal.
The articles receive both rigorous peer-review and expedited online publication.
The journal encourages young researchers to submit their unpublished papers.
The authors retain their article’s copyright.
The authors retain publishing rights without restrictions.
Thus, authors may use their own articles for the following non-commercial purposes without asking our permission (and subject only to acknowledging first publication in Journal of Communications Technology, Electronics and Computer Science and giving a full reference or web link, as appropriate).
Authors cannot submit a manuscript for publication to other journals simultaneously. It is a waste of valuable resources because editors and referees spent a great deal of time processing submitted manuscripts. It is also unethical to republish similar research articles (text/figures/tables) again because journals have limited page space and it most likely violates copyrights which have already been transferred to the first journal. Therefore, all journals require a signed author's copyright transfer agreement stating the originality of the research work submitted through a manuscript. As stated above that authors should submit original, new and unpublished research work to the journal. The ethical issues such as plagiarism, fraudulent and duplicate publication, violation of copyrights, authorship and conflict of interest are serious issues concerning ethical integrity when submitting a manuscript to a journal for publication.
The contents of papers are the sole responsibility of the authors, and publication shall not imply the concurrence of the Editors or Publisher.
