This article discusses the TCP protocol, its shortcomings are examined, and in particular the TCP connections breaks. Existing modifications that allow to remove such shortcomings are considered. The nonoptimality of existing methods is revealed. The method of data transmission control is proposed in the TCP Freeze protocol, which allows to increase the data transmission time. This method is based on dynamic change, depending on the conditions, protocol parameters, which are statically assigned in its original version. Conclusions The efficiency of the data transfer control method used in the TCP Freeze protocol can be improved in a wireless heterogeneous environment by varying the parameters. It was found that if the parameters and their values are equal to the nearest 20, the TCP Freeze and TCP Reno bandwidths will be practically equal. At lower values of parameters TCP Reno shows better performance than TCP Freeze, and at high values of parameters the TCP Freeze bandwidth will exceed TCP Reno's. The use of the proposed method allows to reduce the time of data transmission in the network due to implementation of the algorithm for controlling the size of the floating window of the protocol, which smooths the fluctuations of the latter and leads to a smaller number of retransmissions of data packets, as well as handling the event handover.Downloads
