【摘要】：数据传输能耗是移动网络能耗的重要部分,提高数据传输能耗效率是优化移动网络能耗的重要课题。考虑数据具有传输延时的要求,研究了基于数据到达速率的数据传输平均能耗最小化问题。利用无线信道质量随机变化的特征,构建基于数据到达速率的平均能耗最小化问题,然后将其转化为最优停止问题,证明最优停止规则存在。最后通过求解最优近视停止规则来获得各侦测时刻的最优传输速率阈值,实现基于数据到达速率的数据传输能耗优化策略。对提出的策略与其他策略就平均能耗、平均传递率和平均调度周期进行了仿真对比,结果表明提出的策略具有较小的平均能耗和较高的平均传递率,取得了较好的能耗优化效果。
[Abstract]:Data transmission energy consumption is an important part of mobile network energy consumption. Improving the efficiency of data transmission energy consumption is an important issue in optimizing mobile network energy consumption. In this paper, the problem of minimizing the average energy consumption of data transmission based on data arrival rate is studied. Using the characteristic of random variation of wireless channel quality, the minimum problem of average energy consumption based on data arrival rate is constructed, and then it is transformed into an optimal stop problem. It is proved that the optimal stop rule exists. Finally, the optimal transmission rate threshold at each detection time is obtained by solving the optimal myopia stop rule. The optimization strategy of data transmission energy consumption based on data arrival rate is realized, and the simulation results are compared with other strategies, such as average energy consumption, average transfer rate and average scheduling period. The results show that the proposed strategy has a lower average energy consumption and a higher average transfer rate, and achieves a better energy consumption optimization effect.
