摘　　要：传统传输效率评估方法未考虑数据传输最佳停止规则,不能确定最佳停止时间,导致数据传输能耗较大,评估结果与实际数值不相符。因此,提出一种资源数据传输效率优化评估数学模型,根据已有的传输延迟需求,分析数据速率的传输能耗问题。利用无线信道质量随机变化的特点,将数据平均能耗组建成最小化的框架结构,引入最小化预期成本,进而根据框架确定最佳停止规则,再根据该规则来算出最佳时间停止时间,以此计算不同侦测时间段的最佳传输速率阈值,实现资源数据传输效率的优化;通过网络节点瞬时行为建立数学模型,利用节点丢包率完成对效率优化的评估。根据仿真可知,所提效率优化方法具有较小的平均能耗和较高的传递率,资源数据传输效率得到提升,通过数学模型获得的评估结果与实际值曲线基本一致,证明所提模型具有高精准度。Traditionally,the evaluation method does not consider the optimal stop rule of data transmission,so that the optimal stop time can’t be determined,leading to high energy consumption of data transmission.Therefore,a mathematical evaluation model for optimizing the transmission efficiency of resource data was proposed.At first,the transmission energy consumption of data rate was analyzed according to the existing transmission delay requirements.Based on the random variation of wireless channel quality,the average energy consumption of data was constructed into a minimal frame structure,and then the expected cost was minimized.Furthermore,the best stop rule was determined by the framework,and the best time stop time was calculated by this rule.On this basis,the threshold values of optimal transmission rate in different detection periods were calculated to optimize the transmission efficiency of resource data.Finally,the mathematical model was built by the instantaneous behavior of network nodes,and the efficiency optimization was evaluated by the packet loss rate of nodes.According to simulation results,we can see that the proposed method has lower average energy consumption and higher transmission rate.Meanwhile,the transmission efficiency of resource data is improved.the evaluation result obtained by the mathematical model is consistent with the curve of actual values.Consequently,the model has higher accuracy.
