A method of efficiently transmitting/receiving data using a transport layer in a mobile ad hoc network, and a network device using the method. The method includes a first step of setting, by a sending host, a flag for requesting an ACK-response into a predetermined packet of packets contained in a window for data transmission; a second step of sending, by the sending host, the packet with the flag set thereinto and other packets without any flags contained in the window to a receiving host; and a third step of, by the receiving host, receiving the packets transmitted in the second step, and sending the ACK-response to the packet with the flag set thereinto among the received packets.

Method of efficiently transmitting/receiving data using transport layer in a mobile ad hoc network, and network device using the method

A method for adjusting a transmission rate in the transmission control protocol (TCP) under a mobile ad hoc network environment, including calculating a difference value (Diff) between the current transmission rate (cur_bw) and the previous transmission rate (base_bw), setting up upper and lower thresholds by calculating the standard variation (basebw_var) of the previous transmission rate, and updating the previous transmission rate to the current transmission rate depending upon a comparison result of Diff and the size of the upper and lower thresholds.
