A high accuracy reputation mechanism based on node state prediction has been proposed in this paper to solve the problem of selfish behavior in mobile Ad-hoc networks (MANETs). Firstly, we analyzed the condition of link existing between the dynamic nodes and the condition which packets transport across the link. Based on the above analysis we proposed the(More)
The characteristic of transient response is an important parameter for ultrasonic motors. The transient response measuring system is mostly composed of ARM and a photoelectric encoder and a digital oscilloscope. The design principle and structure of the measuring system and the realization of process are introduced. The validity of the test system is(More)
