Resumo: | TCP wireless networks have its throughput reduced due to channel errors. One of the proposed solutions in the literature for this reduction is Cross-Layer Design. In this work, several Cross-Layer proposals are gathered, categorized and summarized. In order to test the impact of the use of some Cross-Layer proposals, some TCP throughput prediction models were studied. One of the models is corrected and its validity is compared to other TCP model in this work. The comparison of the models shows which of them is capable of predicting the TCP throughput with higher precision when compared to simulated results. Once the best model is known, it is used to prove that there is throughput gain when a chosen Cross-Layer proposal is used. Finally, the impact of the use of another Cross-Layer proposal is analyzed through the creation of a model which is specific to predict the throughput in the considered IEEE 802.11 network and also through the implementation of a Monte Carlo simulator. The analysis of this proposal shows that there is not only a throughput gain, but also the TCP timeouts probability is reduced. |

Uma das solu??es propostas na literatura para diminuir essa degrada??o ? o projeto Cross-Layer. Neste trabalho, v?rias propostas Cross-Layer da literatura s?o reunidas, classificadas e comentadas. Para que o impacto da utiliza??o de algumas propostas Cross-Layer pudesse ser testado, foram estudados modelos de predi??o de vaz?o TCP. Um dos modelos ? corrigido e sua validade ? comparada a outro modelo TCP neste trabalho. A compara??o dos modelos mostra qual deles ? capaz de predizer a vaz?o TCP com maior precis?o em rela??o a resultados simulados. Uma vez conhecido o melhor modelo, ele ? utilizado para provar que h? ganho de vaz?o quando uma determinada proposta Cross-Layer ? usada. Por fim, o impacto do uso de outra proposta Cross-Layer na rede ? analisado atrav?s da cria??o de um modelo espec?fico para predi??o de vaz?o em uma rede IEEE 802.11 e da implementa??o de um simulador de Monte Carlo. A an?lise desta proposta mostra que al?m do ganho de vaz?o, a probabilidade de ocorr?ncia de timeouts TCP ? reduzida.Submitted by Tede Dspace (tede@inatel.br) on 2017-03-24T12:46:12Z No. of bitstreams: 2 license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5) Disserta??o Lucas Mendes.pdf: 991971 bytes, checksum: 5525b80abdd085c4476a33e93c4ecc91 (MD5)Made available in DSpace on 2017-03-24T12:46:12Z (GMT).
