Low power consumption design method based on Android mobile Sink load prediction

A low power consumption design method based on Android mobile Sink load prediction belongs to a low power consumption design method for a mobile Sink node in a wireless sensor network, and particularly is a low power consumption design method for prediction through CPU load; the method comprises the steps that through a CPU driver of Android, the current load load-cur of a CPU is obtained, a historical load value in a history_load [3] array is updated, whether CPU historical load values history_load [1] equals history_load [2] of the first two time periods of current time period in history_load [3[ array is judged, respective current optimal weights Alpha best are calculated, then a CPU load value load_ next of next time period is obtained through calculation, finally a function _cpufreq_driver_target is called, and the working efficiency of the CPU is adjusted based on the predicated CPU load value load_ next. The low power consumption design method based on the Android mobile Sink load prediction can realiz
