Data Stream Controlling in Communication Channels with Noise

Communication throughput is one of the topical issues in computer networks, especially in the channels influenced by the noise from the outside. Existing methods to evaluate the performance of throughput of data link layer protocols are developed under the condition that the absence of the noise is assumed to be lost during the data transmission in the channels. This paper considers the way to manage the throughput parameters of communication protocol on the channels which are impacted by the noises. Throughput management parameters are made of the frame size, the sliding windows size, the nominal speed of data link layer protocol and the inter-frame intervals. Throughput model depends on an error-control method, including the Stop-and-Wait, Go-Back-N, and Selective Repeat, which is used in the ARQ (Automatic Repeat reQuest) protocol and tested in a different environment. An environment parameters include the noise level of the channel, the channel types (wired, wireless, optic), and the type of ARQ protocols for Go-Back-N ARQ protocol method.
