adhoc的csma/ca仿真代码，按802.11的标准执行退避机制，接入信道。(the the adhoc' s csma/ca simulation code, perform backoff mechanism in the 802.11 standard, access channel.)

Intuitive manipulation of a figure using key and mouse gestures(Especially useful for 3d renderings, this widget allows the user to intuitively rotate, pan and zoom any axes within a figure using key presses and mouse gestures. Additionally, press q to quit the widget, r (or double-click) to reset the current axes and escape to close the figure.)
