Traditional wireless Ad hoc networks have the problem of poor network performance under the circumstances of high traffic load.To solve this problem

a distributed full duplex MAC protocol

which combines TDMA and CCFD together

is proposed.In this protocol

all nodes need to do suppression inspecting according to link co-existing schemes before data transmission begins.Then

primary TDMA links start searching secondary links according to the scheduling priority

and send out corresponding requests.The four times hand-shaking process of scheduling process is accomplished within the head of the traffic slot.With no affect on the half-duplex transmissions of traditional TDMA networks

it can increase as many links coexisting with originla links in the same slot as possible.The simulation results show that this protocol actually improves throughput and time delay performances of the wireless Ad hoc networks.
