| Sumario: | The quality of inter-network communication is often detrimentally affected by the largedeployment of heterogeneous networks, including Long Fat Networks, as a result of wireless mediaintroduction. Legacy transport protocols assume an independent wired connection to the network.When a loss occurs, the protocol considers it as a congestion loss, decreasing its throughput in orderto reduce the network congestion without evaluating a possible channel failure. Distinct wirelesstransport protocols and their reference metrics are analyzed in order to design a mechanism that im-proves the Aggressive and Adaptative Transport Protocol (AATP) performance over HeterogeneousLong Fat Networks (HLFNs). In this paper, we present the Enhanced-AATP, which introduces thedesigned Loss Threshold Decision maker mechanism for the detection of different types of lossesin the AATP operation. The degree to which the protocol can maintain throughput levels duringchannel losses or decrease production while congestion losses occur depends on the evolution ofthe smooth Jitter Ratio metric value. Moreover, the defined Weighted Fairness index enables themodification of protocol behavior and hence the prioritized fair use of the node’s resources. Differentexperiments are simulated over a network simulator to demonstrate the operation and performanceimprovement of the Enhanced-AATP. To conclude, the Enhanced-AATP performance is comparedwith other modern protocols |
