摘　　要：在移动Ad Hoc网络中,随着节点移动速度加快和发包强度的增加,造成网络中数据丢包严重,数据传输时延加剧.将整个网络中各节点MAC层的总平均估计时延和节点队列缓存的占用情况结合起来,启用多径路由进行数据传输.仿真实验表明,改进后的方案在节点移动速度比较快时,能够显著提高数据传输成功率,增加网络承受负载能力,提高OLSR的路由传输能力.Due to the increased node speed and increased intensity of sending packets in Ad Hoc, the rate of losing packets and time delay of data transmittal will be aggravated. In this paper, based on the combination of the total path average estimated delay with the buffer occupation ratio of MAC layer, multi-path method was used to transmit data. The findings of this simulated experiment show that the improved solution has a faster node moving speed and it can evidently enhance the success rate of data transmittal and improve the load capacity of network as well as the transmittal capacity of OLSR protocol.
