Nodes in a mobile ad-hoc/sensor networks (MANET) can move at any speed and direction independently. Thus, it's difficult to design a testbed system for network working under such circumstance. Different with traditional software simulation or vehicle-loaded methods, a remote network performance testbed system is proposed in this paper. The main idea of our proposed system is using the rotary motion to create such velocity-changing context. We designed and realized two high speed rotary turntable platforms. Nodes can be deployed on the rotary platform during test, thus it can movement at a speed upto 168 km/h in our testbed system. The operator can remotely monitor the test and receive the testing results simultaneously. Shown by the experiments, the approach is simple, efficient and reliable. In addition, the reason of network packet loss in our testbed is also analysed and tested in this research.
