| 摘 要： | 为了降低WSN中弱硬实时系统的能量消耗，应用离散事件系统（DES）框架中的优化原理，建立数学模型，得到了能量消耗的目标函数，为了最小化目标函数，利用线性规划方法进行求解，得到一种可扩展的低复杂度算法来进行动态电压调节（DVS）。并对算法进行了模型实例计算，结果表明，优化的DVS算法能在满足弱硬实时系统时限要求的基础上更大程度节省节点能量。

| Abstract: | In order to reduce energy consumption of weakly hard real-time system in WSN,adopt the optimal theory of Discrete Event System(DES) framework,establish mathematical model and obtain an objective function of energy consumption.The problem is solved using nonlinear programming for minimize the objective function,then obtain a scalable algorithm of low complexity to determine the Dynamic Voltage Scaling(DVS) controls,and perform the demonstration calculation for the algorithm.The numerical results show that th... |
