Through analyzing and researching the cross-layer model proposed in traditional literatures for the data transmission in wireless sensing networks and the improved version thereof, the problem of the inaccurate data slot selection is found in current cross-layer data transmission mechanism. Then, mini-slot is adopted to improve data frame structure and reduce data transmission conflict ratio, thus to reduce network throughput and energy consumption at the same time. Moreover, the slot function selection process and the mathematical derivation process are provided for the multi-hop network. However, due to the limited experimental conditions at present, the improvement for test site selection, experiment size, etc. can be achieved in future.
