Abstract
A system and method for a media access control (MAC) algorithm with separate operation modes for good channel and bad channel communication. Variables, including channel vector values transmitted in request-to-send/clear-to-send (RTS/CTS) messages (102-1 and 106), are varied depending on channel mode, resulting in optimized system throughput. In a first mode, the present invention provides a system and method to estimate a channel vector length (102-1), and communicate the length to a first node and any associated group s of nodes receiving the RTS/CTS sequence. In a second mode, a maximum channel vector length is used (106), as retransmissions are less probable in good channels.
