We analyzed the requirement of MAC protocol in coal mine, and proposed an improved 802.11 protocol which can adopt RTS/CTS mechanism or not adaptively. This protocol switch the status of RTS/CTS mechanism by comparing the optimal switch value of collision probability with real-time collision probability. The computing formula of switch threshold was given. Simulations show that the adaptive RTS adjustment...
