Effects of the use of an IEEE 802.11 Snoop Agent on TCP timeouts

The development of wireless networks can damage networks Transport Layer operation. There has been much research effort to solve these problems. One of the approaches is known as Cross-Layer Design (CLD), where interactions between non-adjacent layers, forbidden by the layered model, become possible. However, CLD proposals must be carefully tested in order to discover if a gain in one parameter does not result in a loss in any other. Thus, we propose to test the influence of the use of a Cross-Layer Snoop Agent on TCP timeouts. In order to perform this test, we have created a Monte Carlo Simulator and we have presented, in this work, the algorithm followed in its implementation. Also, we have used our analysis to propose an equation to predict the TCP Throughput in the considered scenario, achieving results that agree with the simulated ones. Finally, we have concluded that the use of the Snoop Agent increases TCP Throughput, decreasing TCP timeout probability as well.
