Problems solved by technology

[0025] Therefore, when the TCP congestion control algorithm common to the prior art is applied to a wired-wireless integrated network, even though the actual network is not congested, the TCP performance deteriorates due to the high packet loss rate of the wireless network

Embodiment Construction

[0055] figure 1 is a view of the packet loss process applying common TCP congestion control algorithms to wired-wireless integrated networks.

[0056] which is, figure 1 It is a view of the causes of performance degradation that occurs when the congestion control algorithm used in the TCP protocol is applied to a wired-wireless integrated network. First, data is sent from CN to MN. In response to data from the CN, the MN sends corresponding data. However, when a packet crash (Destroy 1) occurs in the wireless link, the CN does not receive the "Ack" packet during the timeout period. Then, CN mistakenly believes that the network is congested, and calls the congestion control algorithm, starts at a slow rate, and calls the congestion avoidance algorithm to reset the size of the congestion window to 1.

[0057] As mentioned above, the congestion window value is the maximum number of packets that can be sent without any response from the corresponding node in TCP. Therefore, w...

Abstract

A method of Transport Control Protocol (TCP) congestion control using multiple TCP AKCs in an integrated network including wireless links, the method including: receiving a packet retransmitted from a correspondent upon a mobile node having a packet loss in a received packet; calculating the number of acknowledgment messages to be transmitted by the mobile node; generating multiple acknowledgment messages according to the calculated number and transmitting the multiple acknowledgment messages to a transmitting node; and increasing a congestion window value corresponding to the multiple acknowledgment messages received by the transmitting node, and executing the TCP transmission.

Description

technical field [0001] The present invention relates to TCP congestion control using multiple Transmission Control Protocol (TCP) acknowledgments (Acks). More specifically, in a wired-wireless integrated network in which a mobile node performs communication with a wired network server via a TCP connection, the present invention relates to solving a problem that occurs with conventional TCP congestion control by using multiple TCP acknowledgments in order to avoid Performance degradation between TCP end nodes due to packet loss caused by node movement. Background technique [0002] In a wireless-wired integrated environment, a mobile node (MN) has Internet services such as web and e-mail services via a Transmission Control Protocol (TCP) connection with a wired counterpart node (CN) or server. The mobile IP protocol is used to avoid the interruption of the TCP connection flow due to the movement of the MN. [0003] As the popularity of the current MN increases, users' deman...
