Abstract:
1. A method for dynamically changing an RTS (Request To Send) threshold so as to enhance a MAC (Medium Access Control) throughput of a wireless LAN, the method comprising: (a) initializing a performance index represented by a ratio of a total time taken to successfully transmit a data frame to a total time taken to transmit a MAC frame; (b) waiting for a updating period of the RTS threshold, and setting a previous performance index as a first performance index, and a performance index previous to the first performance index as a second performance index; and (c) comparing the size of the first performance index with the size of the second performance index, and adding a difference between first and second preceding RTS thresholds temporally corresponding to the first and second performance indexes, respectively, to a current RTS threshold, so as to update a third RTS threshold.
