In this paper, we present a new collision free MACprotocol - multi-channel Binary-countdown-carrier-sense /Request-to-send (RTS) / Object-to-send (OTS) / Agree-to-send(ATS) / Disagree-to-send (DTS) / Ensure-to-send (ETS)/ Neaten-to-send (NTS) (BROADEN) for ad hoc wirelessnetworks that can achieve 100% collision free performance.Furthermore, it can totally solve the "exposed terminal","hidden terminal", and "moving terminal" problems. It willalso decrease the bandwidth consumed per transmitted datapacket and thus improve the network's performance indecreasing the average delay of packet sending, droppingdiscard ratio, and increase the network's throughputsignificantly. Finally, the scheme can enable differentpackets with different priorities access the media accordingto their priority level and thus gain their desired QoS.
