Devices using DENIAL-TO-SEND and delay CLEAR-TO-SEND in a wireless network of directional, methods and articles

摘要

For the directivity of the radio communication, in order in particular to avoid the hidden node problem of directivity of the network, to the RTS (Request-to-Send), at least one new response is created. Depending on the RTS received during the NAV period, DTS (Denial-to-Send) it is transmitted. DTS is a device that responds is, but not be able to communicate at the moment because the NAV is set, after the expiry of a defined period in the DTS indicating that it is ready to communicate.
