摘　　要：分析了在移动自组网中IEEE 802.11 MAC协议的隐藏终端和暴露终端问题以及数据流调度的不公平性，并利用仿真方法研究了基于节点移动、通信干扰以及调度的非公平性等因素情况下，不同的传输范围对节点平均吞吐量、报文丢失率、端到端的报文延时的影响。The paper analyzes the defects of IEEE 802.11 MAC protocol about the hidden terminal, exposed terminal and the unfair scheduling of data flows in mobile Ad Hoc network. By the simulation it researches different transmission ranges which give the effects on the average throughput of nodes, dropped packet ratio, end-to-end packet delay based on the factors of node mobility, the interference of communication and the unfair scheduling.
