摘　　要：提出一种Ad hoc网络的MAC层协议策略,运用了跨层的设计方法以及无线资源管理接入控制策略中多用户分集的思想。在MAC层,通过对物理层信道质量的判断,节点选择信道质量最好的节点进行数据传输。这样,系统中数据包的冲突有所减少。In this paper, a new strategy for MAC layer of Ad hoc network is proposed. The strategy exploits the concept of cross layer design and multiuser diversity in radio resource management （RRM）. At the MAC layer, by judging the quality of the channel, a node chooses another node with the best channel quality to transfer data. Through the use of this strategy, the system can avoid some inside interference, and the number of packets that successfully transferred in the system is increased.
