摘　　要：利用多包接收的方法和跨层设计的思想,提出一种基于IEEE802. 11接入控制策略中的RTS/CTS机制,来实现无线AdHoc网络媒体接入的算法,并对新算法进行了理论分析和仿真。分析结果表明与传统的RTS/CTS机制相比,该算法有效地提高了无线AdHoc网络的吞吐量。Utilizing multi-packet reception method and cross-layer design idea, a media access control algorithm for Ad Hoc network was presented, based on the RTS/CTS multiple access protocol of IEEE 802.11 DCF MAC(Media Access Control).The performance of algorithm was analyzed. The results show that the network throughput is greatly improved, compared with the conventional RTS/CTS protocol.
