To resolve hidden terminal and exposed terminal problems and improve the probability of simultaneous data packet transmissions for multihop mobile ad hoc networks (MANETs), we propose a novel dual channel reservation (DCR) medium access control (MAC) protocol. The protocol achieves simultaneous collision-free contention reservation access and data packet transmission and optimal load balance between the packet transmissions on reservation channel (RCH) and traffic channel (TCH) by appropriately adjusting the data rates of the RCH and TCH and guaranteeing the same interval of reservation slot on the RCH as that of data packet transmission slot on the TCH. Finally, simulation results show that in the presence of the same total data rate, the DCR protocol obviously outperforms the IEEE 802.11 distribution coordination function (DCF) protocol in terms of multiple access performance.
