Ad hoc network is a multi-hop, no center, and self-organizing wireless network. The network has no fixed infrastructure, each node is mobile, and can be in any way to keep in touch with other nodes dynamically. Each node is a router at the same time; they can find and maintain complete routing functions to other nodes. Due to the use of wireless communication and therefore more vulnerable than wired network interference enemy, eavesdropping and attack. To confirm the information transmitted process, reduce system idle time, improve the system controllability, this paper proposed a dual clocks three-dimension probability random multi-channel access protocol with ACK mechanism. Its basic principle is that the channel is the continuous clock manner during channel is idle and the channel is the slot time manner during channel is busy. Use three-dimension probability to control the system throughput. With ACK mechanism, confirm the process of transmitting information.
