摘要
分析了移动ad hoc网络相关衰落信道下的802.11 DCF的吞吐量以及帧长度对吞吐量的影响。研究表明移动速度越高,吞吐量越低;在一定的移动速度下存在最优的帧长使得系统吞吐量最大,并且该最优值与发送节点的数目无关。
The throughput of 802.11 DCF over MANET correlated fading channel and the impact of frame length on 802. 11 DCF performance are investigated in this paper. The study shows that the throughput decreases with the increase of mobile velocity and there exists an optimal frame length to maximize throughput under a certain velocity, moreover, the optimal length is independent of the number of nodes.
