Among them, anonymous communication is one of the important problems to be achieved in wireless. There were studies on anonymous communication, but they usually focused on the routing problem. But considering routing problem might make the solution complicated. So it is worthy to be considered that we take advantage of already-developed mix system for the Internet with slight change. So, in this paper, we will present the way how to use already-developed mix system in wireless ad hoc network.
