摘要
由于物联网环境下的设备众多,各个设备之间存在十分复杂的关联性,能量损耗较大,采用传统的调度方法建模时,由于关联性需要加入大量约束条件完成调度过程,在复杂的调度过程中,无法用约束满足所有的线性调度关系,导致建模误差大的问题。提出采用多目标模糊算法的能量损耗优化调度建模方法。先以物联网环境下的设备调度耗能成本、设备调度时间为依据,构建物联网环境下的多目标设备调度优化方程,融合于模糊算法将能量损耗的多个目标问题转换为单目标问题,建立物联网环境下的设备调度能耗模型,并搜索设备的空闲时间,建立的设备调度能耗模型进行优化,进而降低物联网环境下的设备调度整体耗能。实验结果证明,基于多目标模糊算法,使考虑能量损耗的物联网环境下的设备调度建模方法建模精确度高,节能效果好。
An energy loss optimization scheduling modeling method is proposed based on the multi -objective fuzzy algorithm. According to energy consumption and equipment scheduling time under the Internet of Things envi- ronment, a multi - objective optimization equipment scheduling equation is built, and a multiple - objective optimiza- tion of energy loss is transformed to a single objective optimization by fusing the fuzzy algorithm. An equipment scheduling model of energy consumption is set up, and the equipment idle time is searched. The energy consumption equipment scheduling model is optimized, and the overall energy consumption of equipment scheduling under the In- ternet of Things environment is reduced. Simulation shows that the proposed method has high precision and good en- ergy saving effect.
