Method for dynamic control of RTS threshold to improve throughput of MAC in wireless LAN system, and computer-readable medium thereof

摘要

Disclosed is an algorithm for dynamically changing an RTS threshold, which is a threshold for RTS-CTS frame exchange, depending on the traffic load in the BSS so as to maximize the MAC throughput of an IEEE 802.11 wireless LAN system. The present invention defines a new performance index based on the total time taken to transmit a frame and the time taken to successfully transmit a data frame. The RTS threshold is dynamically increased/decreased in a predefined range depending on the change in the new performance index.
