移动的自组织网络（Ad hoc Network，MANDO）是指在移动的节点之间建立无线连接，并能动态扩展无线局域网（Wireless Local Area Network，LAN）的覆盖范围。对于使用单个信道的移动自组网，由于帧被中继时节点之间的干扰，通信性能降低。本文提出了一种基于邻居节点行为的优先级控制方案。节点持续监视邻居节点，并使用监视结果自行确定传输优先级;当节点成功发送帧时，优先级降低，而当节点检测到来自邻居节点的发送帧时，优先级增加。我们评估了我们所提出的方案的有效性，使用模拟，结果表明，我们所提出的方案的吞吐量是至少约700 kb/s高于使用IEEE 802.11a的MANET。
Mobile Ad-hoc Networks (MANETs) involve the establishment of wireless connections between mobile nodes, and can dynamically extend the coverage area of wireless local area networks (LAN). For MANETs that use a single channel, the communication performance decreases due to interferences between nodes when frames are being relayed. In this paper, we propose a priority control scheme based on neighbor node behavior for MANETs. A node continuously monitors neighbor nodes and determines a transmission priority on its own using monitoring results; the priority decreases when the node transmits a frame successfully, and increases when the node detects a transmitted frame from neighbor nodes. We evaluated the effectiveness of our proposed scheme using simulations, and results show that the throughput of our proposed scheme is at least approximately 700 kb/s higher than that of a MANET that uses IEEE 802.11a.
