摘　　要：针对实际应用中的Ad hoc组网性能与移动场景的关系进行测试分析,利用机动车、火车、动车、地铁等交通工具,在隧道、弯道、平地、坡度、地下等不同场景的高速移动条件下,运用相关软件对基于Ad hoc组网的移动WLAN网络进行传输性能的测试。参照对实验数据的对比和分析,提出在高速移动场景下Ad hoc网络节点间位置和所处电磁环境对WLAN信号和平均传输速率的影响,同时,初步验证了移动端点以不同的轨迹和速度运动时,信号衰落情况的不同。Based on analysis of the relationship between network performance and mobile scenario of Ad hoc in practice, by using transportation tools of cars, trains, subways and so on under conditions of different highspeed mobile scenarios including tunnel, curve path, slope, underground, the test on Ad hoc-based mobile WLAN network transmission performance is done. In the light of comparation and analysis of the experiment data, this paper proposes the influence of network node location and EM environment on WLAN signal and average transmission rate under conditions of high-speed mobile scenarios. Meanwhile, the experiment priliminrily verifies the difference of signal decline when the mobile endpoint moves with different trajectories and speeds.
