ABSTRACT:
In a wireless network having one or more base stations and one or more access points, the base station is switched automatically from a CSMA/CA exchange protocol to an RTS/CTS exchange protocol, in a case where the base station infers the presence of a hidden node. The presence of a hidden node is inferred by scanning frames of wireless network transmissions to and from other base stations and the access point. In a case where there is a discrepancy in the accrued frames, such that frames have been accrued from the access point to a second base station without also accruing frames from the second base station back to the access point, the presence of a hidden node is inferred, and the base station is switched automatically to RTS/CTS exchange mode.
