摘　　要：在移动无线传感器网络中,MAC协议采用包分割的方法进行数据传输。当分割的数据包较大时,数据包传输出错的概率较大;当分割的数据包较小时,会增加控制开销和传输总时间,影响移动节点间的通信。通过构造基于数据包传输时间效率的最优化模型来说明数据传输时间与最优数据包长之间的关系。通过仿真验证了这种关系。In mobile wireless sensor networks,MAC protocol transmits data in the way of packet segmentation. When the packet length is segmented longer,the probability of packet transmission error will be bigger; when it is shorter,the control cost and transmission total time will increase and will influence the communication process between the mobile nodes. In this paper we illustrate the relationship between the data transmission time and the optimal packet length by constructing the optimised model which is based on the time efficiency of data packet transmission. The relationship is verified by simulation.
