Generation of information technology. IoT will be the next “significant productivity” to promote the world in rapid development. To truly establis h an effective IoT, there are two important factors: first, the scale; second, liquidity. But due to relatively high mobility and application environment is more complex, how to enhance controllability and the accuracy of information transmission is particularly important when design the transmission protocol. To solve the problems : safety of information transmission, the hidden terminal and exposed terminal, this paper introduces double clocks three-dimension probability random multi-channel access protocol with three-way handshake mechanism. Make the transfer of information more securable, solve the problem of the hidden terminal and exposed terminal, and improve the performance of the system by the introduction of three-way handshake mechanism. Improve the system controllability by the three -dimension probability mechanism. And use the averaging cycle period conduct analytical and simulation experiment with the control strategy mentioned above. Shorter the system idle time by the double clocks mechanism and improve the utilization of channel resources.
