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。
According to the actual application of Ad hoc network performance and the relationship between mobile scenarios for testing and analysis, the use of vehicles such as motor vehicles, trains, motor cars, subways and other transport, in tunnels, corners, flat, slope, underground and other high-speed moving conditions Under the use of related software for mobile network based on Ad hoc network WLAN transmission performance testing. Based on the comparison and analysis of the experimental data, the influence of the position and the electromagnetic environment of nodes in the Ad hoc network on the WLAN signal and the average transmission rate under high-speed mobile scenarios is proposed. At the same time, the movement endpoints are preliminarily verified to move at different trajectories and speeds When the signal fading situation is different.
