Abstract：CM-MAC protocol proposed is a Mobile Ad Hoc Networks MANETs) medium access control(MAC) protocol based on clustering structure.The protocol is mainly applicable to largescale multi-hop mobile ad hoc networks.It uses clustering technology to divide the entire largescale network into many clusters.These clusters do not interfere with each other because each cluster has a different operating frequency band.In a cluster,a dynamic TDMA protocol is used and network resources are dynamically occupied by nodes according to their traffic lows.Intercluster communication is realized through gateway nodes.In the end we use OPNET Modeler software to model and simulate the CM-MAC protocol.The results show that,in the large-scale network,the CM-MAC protocol increases throughput at about 2.2 times,improves slot reuse rate at about 4 times,and reduces the end-to-end delay at about 3 times than the standard USAP protocol.
