IEEE802.11DCF employs RTS/CTS (Request To Send/Clear To Send) mechanism for mitigating effect of hidden terminals. The RTS/CTS mechanism sets transmission deferral timer to neighbor terminals by exchanging RTS and CTS between transmitter and receiver

Hidden terminals can significantly lower the throughput of such competitive MAC protocols as CSMA. Therefore, a large number of MAC protocols that implement different hidden terminal strategies have been developed. In this paper we propose an algorit

This paper notes that the modulation scheme used in MIMO (multiple-input multiple-output) system has only discrete spectral efficiency, which in addition has an upper limit from the viewpoint of implementation. A capacity-controlled MIMO adaptive mod
