Limited power supply is the uppermost constraint factor to sensor network performance and lifetime.Based on processor task scheduling of sensor network node

this paper put forward voltage and sleep dual-effective scheduling algorithm in term of dynamic power management and dynamic voltage/frequency scaling

namely DV/FS-RM and DV/FS-EDF.On the premise of guarantee node real time performance

the policy can not only dynamically control idle task to enter sleep mode but also reduce processor frequency to achieve better power save effect through DV/FS-RM or DV/FS-EDF algorithm.Experiments show that the effect of the power aware task scheduling algorithm is remarkable which can extends the lifetime of sensor network node several times which mainly depend on batteries power supply.
